Tobacco industry denormalisation as a tobacco control intervention: a review



To conduct a review of research examining the effects of tobacco industry denormalisation (TID) on smoking-related and attitude-related outcomes.


The authors searched Pubmed and Scopus databases for articles published through December 2010 (see figure 1). We included all peer-reviewed TID studies we could locate that measured smoking-related outcomes and attitudes toward the tobacco industry. Exclusion criteria included: non-English language, focus on tobacco use rather than TID, perceived ad efficacy as sole outcome, complex program interventions without a separately analysable TID component and non peer-reviewed literature. We analysed the literature qualitatively and summarised findings by outcome measured.

After excluding articles not meeting the search criteria, the authors reviewed 60 studies examining TID and 9 smoking-related outcomes, including smoking prevalence, smoking initiation, intention to smoke and intention to quit. The authors also reviewed studies of attitudes towards the tobacco industry and its regulation. The majority of studies suggest that TID is effective in reducing smoking prevalence and initiation and increasing intentions to quit. Evidence is mixed for some other outcomes, but some of the divergent findings may be explained by study designs.


A robust body of evidence suggests that TID is an effective tobacco control intervention at the population level that has a clear exposure–response effect. TID may also contribute to other tobacco control outcomes not explored in this review (including efforts to ‘directly erode industry power’), and thus may enhance public support and political will for structural reforms to end the tobacco epidemic.


Population level interventions have demonstrated over the past two decades that measures altering the social context of tobacco use can significantly reduce smoking prevalence.14 Tobacco industry denormalisation (TID), a focus of several successful tobacco control initiatives in the US and elsewhere, is increasingly regarded as essential to effectively addressing tobacco at the population level. Beginning with the ‘vector analysis’5 which first emphasised tobacco industry activities, rather than smokers’ individual behaviours, as critical for tobacco control, a focus on the supply side in advocacy, research, policy and programme planning has appeared.2, 68 This emphasis, represented in specific provisions in the World Health Organisation’s Framework Convention on Tobacco Control (FCTC),9 has not been universally embraced. In some countries, efforts still focus primarily on health education and prohibitions on youth tobacco sales. Some TID efforts have met with aggressive tobacco industry responses, occasionally including lawsuits aimed at curtailing them.10, 11

Mahood12 distinguishes between the denormalisation of tobacco use (which focuses on the addicted individual) and the denormalisation of the industry, arguing that only the latter offers the prospect of addressing the chief structural cause of the tobacco disease epidemic: industry activity. In this paper we use ‘tobacco industry denormalisation’ to mean themes, campaigns and perspectives aiming towards ‘the reversal of the process of industry normalisation promoted by cigarette manufacturers for decades’.12 The rationale for TID is captured by the first principle of the Guidelines for implementing Article 5.3 of the FCTC: ‘there is a fundamental and irreconcilable conflict between the tobacco industry’s interests and public health policy interests’.13

No previous reviews have specifically examined the effectiveness of TID as a tobacco control strategy. We review evidence on TID and smoking-related outcomes. We analyse why some findings appear to diverge from the bulk of published literature. The evidence suggests strongly that TID is an effective strategy that should be part of comprehensive tobacco control.



We searched the PubMed and Scopus databases for articles published through December 2010 using the following search terms: (‘Tobacco Industry’ (Mesh) OR ‘tobacco industry’) AND (delegitimization OR delegitimation OR denormalisation OR de-normalisation OR de-normalization OR anti-industry OR counter-industry OR vilification OR industry manipulation); ‘tobacco industry’ AND (deception* OR mistrust* OR lie* OR lying OR false allegation); (‘tobacco industry’ (Mesh) OR ‘tobacco industry’ OR tobacco) AND (countermarketing OR counteradvertising); (‘tobacco industry’ (Mesh) OR ‘tobacco industry’ OR tobacco OR smoking) AND ‘truth campaign’; (‘tobacco industry’ (Mesh) OR ‘tobacco industry’ OR tobacco OR smoking) AND (truth OR ‘truth campaign’); and (‘tobacco industry’ (Mesh) OR ‘tobacco industry’) AND (opinion* OR perception* OR belie* OR ‘support for action’ OR attitude*) (see figure 1). Peer-reviewed research was included if it measured effects of TID on tobacco-related behaviours, attitudes towards industry and support for tobacco control policy (see figure 1). Studies were included from any country, involving any population that measured smoking or tobacco-industry related outcomes. Exclusion criteria included: non-English language, focus on tobacco use rather than TID, perceived ad efficacy as sole outcome, complex programme interventions without a separately analysable TID component and non-peer-reviewed literature.

The searches yielded 891 articles (figure 1). RM and QG independently identified 54 articles meeting inclusion criteria. LB reviewed discrepancies; final selection was achieved by consensus. Six additional articles were identified from reference lists. QG read the 60 articles and abstracted information using a data collection form.


Studies were grouped for descriptive analysis by type of outcome measured. Six studies used structural equation modelling to theorise links between TID and smoking-related outcomes and were summarised separately.


Study characteristics

The 60 articles represented 56 unique studies (table 1). Most were conducted in the US (n = 46; 82%). Several regions and counter-industry campaigns were represented: the national ‘truth’ campaign (n = 15), the Florida ‘truth’ campaign (n = 9), the Minnesota Initiative, Target Market (n = 3), the Wisconsin Campaign (n = 2), the Mississippi campaign (n = 1) and a media literacy programme in Washington (n = 1).

Table 1
Characteristics of included studies

Nine smoking-related outcomes were measured (see table 1). All were measured using self-report. Three studies employed qualitative methodologies. Cross-sectional designs dominated (n = 37; 66%); 23 of these used repeated measurements. Four studies were longitudinal. There were several quasi-experimental designs: controlled comparison (n = 1), controlled before and after (n = 3), historically controlled (n = 3) and controlled experiment (n = 1). Four studies were randomised controlled trials (RCTs).

In all, 38 studies employed random sampling (60%). The most commonly used sampling frame was a vendor-generated telephone list (n = 34; 54%). Middle and high schools were the next most common (n = 10; 16%). Several studies used the same data sets: the Legacy Media Tracking Surveys (LMTS), sponsored by the American Legacy Foundation (ALF) (n = 14); the Florida Youth Tobacco Survey (FYTS), sponsored by the Florida state Department of Health (n = 2), and the Florida Anti-tobacco Media Evaluation (FAME), through Florida State University (n = 5). These data sets were representative of their population; LMTS oversampled racial and ethnic minorities.

Youth aged 12–17 were the focus of most studies (n = 37; 59%). Three used an extended definition of youth: ages 12–25 years. Five examined young adults, defined as either 18–25 years (n = 4) or 18–29 years (n = 1). A total of 15 studies included adults, 2 requiring adults to have children aged 12–17. Three studies employed mixed youth/adult samples.

A conflict of interest exists when campaigns are evaluated by implementing agencies. In Florida, the Department of Health contracted for an independent evaluation.14 Twelve studies evaluating the national ‘truth’ campaign were funded by the ALF, 2 by other sources; 3 did not disclose funding. These studies’ principal researchers are housed at ALF, RTI International, Centers for Disease Control, American Institute for Research, RAND Corporation and other academic research centres. It appeared that none of the researchers were responsible for data collection through FAME, FYTS or LMTS surveys and many acknowledged external survey management companies.

Smoking prevalence

TID’s relation to smoking prevalence was examined in 13 studies. Measured by self-report, studies most commonly employed 30 day and 100-cigarettes-in-lifetime referents, placing respondents on a 3–5 classification continuum (table 1). This measure is widely used and appropriate for youth and young adults, capturing the construct of smoking initiation and progression to smoking dependence.

Smoking prevalence: youth

The first youth campaign to be highly funded and thoroughly evaluated was the ‘truth’ campaign piloted by the state of Florida, launched in April 1998, featuring a strong TID component. Surveys following Florida ‘truth’s’ implementation showed large decreases in smoking prevalence among youth ages 12–171416 and similar decreases for prevalence in all categories along the smoking behaviour continuum.15 Prevalence of never users and those defined as committed non-smokers rose significantly.15 Less than a year after campaign launch, non-smoking youth who remained non-smokers were 2.3 times more likely than those who started smoking to say they were influenced ‘a lot’ by the ‘truth’ campaign’s primary, industry manipulation message.14

At 2 years into the Florida campaign, national ‘truth’ was launched, permitting comparisons between Florida and national youth. Florida youth were significantly less likely than national youth to have smoked in the past month, or to have ever tried smoking.17, 18 Florida youth also held less favourable beliefs about the tobacco industry.17 Predictive of smoking behaviour in the past 30 days were two beliefs central to the campaign: ‘cigarette companies lie’ and ‘cigarette companies try to get young people to start smoking’.17 However, 4 years after campaign termination a reversal was seen: although most youth were still able to confirm ‘truth’ campaign awareness, smoking rates for youth had increased 6.8%.16

Three studies examined counter-industry media campaign effects on smoking prevalence among a national youth sample. One compared youth smoking among states with long-term funded, recently funded, or no counter-industry campaigns.19 The rate of decrease in youth smoking rates in states with established or new campaigns versus those without was nearly double; similarly, odds of current smoking were reduced significantly faster in states with counter-industry campaigns than in those without.19 Over time, negative beliefs and attitudes about the tobacco industry showed significantly stronger relationships with smoking status in campaign versus non-campaign states.19

In a large, random, national sample of youth ages 12–17, higher sensation seeking and weaker counter-industry attitudes were independent predictors of current smoking.20 The relationship between counter-industry attitudes and smoking behaviour was consistent across risk groups, suggesting that counter-industry messages may be equally effective for high and low risk youth.20 In Canada, a school-based survey of high school students showed that decreases in occasional and regular smoking behaviour were significantly related to TID beliefs.21

A historically controlled experiment examined the effects of increased exposure to the national ‘truth’ campaign.22 Researchers found a significant inverse relationship between ‘truth’ exposure and youth smoking prevalence; however, this effect diminished at higher exposure levels.22 Researchers concluded that roughly 22% of the 36% decline in youth smoking prevalence from 1997 to 2002 was attributable to the national ‘truth’ campaign.22

ALF and the Washington State Department of Health partnered to implement and evaluate a tobacco media literacy curriculum about deceptive industry advertising tactics.23 Although the programme had significant effects on other measures of tobacco attitudes, beliefs and behaviours, it had null effects on smoking prevalence.23

Smoking prevalence: young adults

Three cross-sectional studies measured smoking prevalence in young adults. Counter-industry attitudes and beliefs, including support for action against the industry, were strongly, negatively associated with current smoking in all three.2426 Among US Air Force recruits prior to a mandated cessation programme, the strongest predictor of smoking status was attitude towards the tobacco industry.26 Along the smoking status continuum, former smokers relative to never smokers, experimental smokers relative to never smokers and current smokers relative to former smokers were less likely to agree with the statement ‘tobacco companies lied/misled the public’.26

Smoking initiation

Five studies measured smoking initiation. Smoking initiation is generally only applicable in measuring youth smoking behaviours: four of the studies surveyed samples aged 12–20. However, one examined enforced cessation during Basic Military Training as an intervention, which allowed for measurement of relapse/initiation.26 Relapse was less likely among baseline smokers who agreed with statements about the industry’s deceptive practices.26 However, attitude towards the industry was not a significant predictor of smoking initiation between baseline ‘never’ or ‘experimental’ smokers.26

The relationship between smoking initiation and the national ‘truth’ campaign was examined in two longitudinal surveys. More frequent ‘truth’ recall was associated with both decreased likelihood of smoking initiation and tobacco dependence.27 Increased cumulative campaign exposure was associated with a 20% decrease in initiation risk of over a period of 7 years.28

Two repeated cross-sectional surveys examined progression of non-smokers to smokers in association with Florida’s ‘truth’ campaign, finding evidence of an inverse relationship between increased exposure to truth and smoking initiation over a period of 22 months.29 Rates of smoking initiation for baseline non-smokers varied inversely with the number of ‘truth’ ads recalled, the reported influence of the counter-industry theme and the strength of industry manipulation attitudes.29 In another study, compared with those unaffected by the campaign, youth reporting low or high anti-industry ad effects were 1.3 and 1.7 times more likely to remain non-smokers by the second survey.30

Intention to smoke

In all, 17 studies measured intention to smoke.

Intention to smoke: youth

Florida’s ‘truth’ campaign was associated with increases in the proportion of youth ages 12–17 who identified as ‘closed to smoking’ and experimenters who stated they would not smoke again.15, 31 Florida teens were also less likely than their national counterparts to be open to future smoking.17 However, after the state cut funding for the programme in 1999, trends in non-smoking intentions were significantly reduced.31

Two components of the Minnesota counter-industry campaign Target Market (TM) were studied: TM/org (youth organising) and TM/ads (mass media). No significant relationship was found between exposure to TM/org and intention to smoke.32 However, youth with greater intentions to smoke scored significantly lower on certain attitudinal items such as ‘teens have been influenced by the tobacco industry’.32 Termination of the TM/ads component had negative impacts on prevalence of respondents scoring highly on industry manipulation attitudes/beliefs, and prevalence of participants not intending to smoke in the next year.33

A study of Wisconsin’s counter-industry themed campaign found that positive attitudes towards the campaign and number of ads seen were significantly, negatively associated with smoking intentions.34

In a repeated cross-sectional study during the first 3 years of the national ‘truth’ campaign, campaign recall was associated with greater odds of youth ages 12–17 ruling out future smoking.35 Higher sensation-seeking traits and weaker counter-industry attitudes independently predicted intention to smoke.20 Another repeated cross-sectional study of this same population found no statistically significant increase in the percentage of non-smokers saying they probably/definitely would not smoke in the next year; however, six of nine counter-industry and empowerment attitudes were strongly associated with reduced smoking intentions.36 Analysis of racial/ethnic data found a significant association between ‘truth’ exposure and belief and attitude indices, but the impact, though similar for white and African–American youth, was lower for Hispanic youth.37 Though most youth across racial/ethnic subgroups do not intend to smoke at baseline (94%), exposure to ‘truth’ was associated with 2.0 greater odds of not intending to smoke among never smokers and 5.7 greater odds among ever smokers, across all racial/ethnic subgroups.37

A longitudinal study of youth at low and high risk for smoking showed that those exposed to the national ‘truth’ campaign were more likely to hold anti-smoking beliefs at follow-up, and more frequent ‘truth’ recall was significantly associated with decreased likelihood of developing openness to smoking, intentions to smoke soon and in 5 years, but not for intentions to smoke within 1 year.27

Three studies used RCTs to investigate the effectiveness of different message themes on adolescents’ intentions to smoke.3840 These concluded that industry manipulation-themed ads were ineffective in decreasing intentions to smoke. One study randomised 7th and 10th grade students (44% Hispanic) to eight different ad conditions (two of which could be considered TID-themed) and a control group.38 Two TID-themed ads enhanced health risk severity perceptions. One TID theme positively influenced 10th graders’ perceived vulnerability to social disapproval risks.38

Ninth grade California students were randomised to nine ad conditions, three of which were ‘counter-industry’ type.39 Among all participants, no ad type lowered intentions to smoke versus the control.

A third study randomised 16 groups of Virginia high school students to 1 of 3 message theme conditions (where 1 was industry manipulation), or a control.40 Those viewing ads portraying negative life circumstances of smokers had lower intentions to smoke than either control or industry manipulation ad groups.40

Intention to smoke: adults

Evidence for TID’s effects on intention to smoke among adults is less consistent, perhaps because most campaigns targeted youth. No significant association between campaign awareness and intention to not smoke was found for young adults aged 18–24 in relation to the national ‘truth’ campaign.41 However, several specific attitudes/beliefs promoted by ‘truth’ were associated with intention to not smoke such as, ‘I would like to see cigarette companies go out of business’.41 Another study surveying general counter-industry attitudes among adults found support for counter-industry action was negatively associated with intention to smoke within the year.25

Two controlled before and after studies examined TID and intention to smoke in the context of movies. Surveyed Australian adults viewed The Insider (a film about tobacco industry duplicity) or the control Erin Brokovich (plot analogous but not about tobacco). The The Insider group showed a decline in intentions to smoke at the post-film survey and a divergent trend from the control group for current, former and non-smokers.42 However, when late responders were included, these effects were non-significant, suggesting the film’s impact may have been transitory.42 A historically controlled experiment with cinemagoers seeing an industry manipulation-themed advert prior to viewing their film found a greater proportion of non-smoking participants in the intervention group agreed that smoking in movies was ‘not OK’, but a significantly higher percentage of smokers in the intervention group said they would still be smoking in 12 months.43

Intention to quit

Eight studies8, 24, 25, 34, 41, 4449 examined TID’s effects on intentions to quit smoking. All used a single-item measure with adults. Several cross-sectional studies found that beliefs about industry deceptiveness were positively related to consideration of quitting,34, 44, 45 as was support for counter-industry action.24, 25 Another study found that supporting action against the industry was positively associated with quit intentions, but not with a serious quit attempt.25 In a longitudinal study in four Western nations, smokers reporting medium and high TID beliefs were more likely to intend to quit, and although TID beliefs at time 1 did not predict abstinence at time 2, smokers with stronger beliefs at time 2 were more likely to be abstinent than those who beliefs did not increase.8

Although exposure to the national ‘truth’ campaign was not associated with intention to quit smoking among young adults, seven of nine counter-industry belief/attitude items targeted by the ‘truth’ campaign were associated with intention to quit among young adult smokers.41 Awareness of Florida’s ‘truth’ campaign reached approximately 50% of adults, and the only variable significantly associated with quit intentions was awareness of the industry manipulation theme, independent of parental status.44, 45 However, in an evaluation of Wisconsin’s campaign, beliefs about industry deceptiveness were not significantly related to quitting considerations.49

One study examined effectiveness of ad themes on college students’ tobacco use, including intention to quit. College students assigned to TID-themed ads were twice as likely to intend to quit as those who viewed social norms ads.47

Other outcomes

Youth generally overestimate perceptions of peer smoking prevalence (PPSP); it may be a precursor to future smoking.50 Two studies suggested that TID is associated with lower PPSP.23, 50 Evidence from two studies of smoking resistance self-efficacy (SRSE), which is predictive of youth smoking, was mixed: TID-themed ads were associated with lower SRSE scores than ads emphasising the effects of smoking.51 However, industry manipulation ads were associated with greater SRSE when they used less, versus more appealing actors.51 Explicit industry manipulation messages (vs implicit) were associated with stronger SRSE.52 One RCT found that no tested message themes affected SRSE or marketing resistance self-efficacy.38 TID-related activities were associated with higher empowerment (the degree to which youth feel they would like to get involved in organising against the tobacco industry and feel youth can make a difference) scores.32, 53 However, youth with higher intentions to smoke were less likely to believe that youth could be effective.32

Attitudes towards industry and its regulation

Views of industry

Across diverse samples, tobacco companies were regarded as dishonest, unethical and less trustworthy than other companies.42, 5457 Negative views of industry appeared to be increasingly negative over time.55, 57 Australian smokers had stronger counter-industry beliefs than either Canadian or UK smokers; UK smokers reported weaker counter-industry beliefs than US or Canadian smokers.8 A minority of Russian adults felt tobacco companies behaved unethically, despite three-quarters agreeing that tobacco companies definitely or maybe bribed politicians.58 Rather than being a TID marker, this behaviour was considered typical for a Russian corporation.

There is some evidence that support for the process of TID is weaker among smokers;42, 5456 however,59 in one study smokers were polarised on these beliefs.55 Smokers from four countries reported relatively strong counter-industry beliefs, especially among the older and more educated.8 Women smokers were less likely to report counter-industry beliefs than men.8

In a Canadian study, youth appeared less distrustful of tobacco companies than adults, a consistent finding across smoking categories and school grade.57 African American youth focus group participants, however, expressed anger at tobacco industry targeting, considering it a form of racism.60 A Florida survey found non-smoking youth more likely than smoking youth to espouse counter-industry attitudes.59

One cross-sectional study surveyed adult African–Americans’ views about black organisations accepting tobacco industry philanthropy.61 Despite most agreeing that philanthropy makes the industry money and encourages smoking, one-third said it also helps the community.61 Those with college educations and men were less likely to find this philanthropy acceptable; younger adults were less likely to agree that this philanthropy aimed to help communities.61

Views of regulation

There were varied opinions ranging from neutral to strong beliefs about industry responsibility for smokings’ harms and its regulation. Descriptive research has assessed attitudes towards tobacco industry regulation in diverse samples including: adults in Ontario;54 Mississippi parents before and after a youth-targeted, counter-industry state media campaign;62 Korean immigrant, male smokers;63 school nurses64 and New Zealand politicians.65 In a sample of smokers in four countries, thinking about the conduct of tobacco companies and belief that the industry should take more responsibility for tobacco’s harms were independently predictive of support for industry regulation,46 and counter-industry beliefs were associated with noticing anti-smoking information, tobacco ads and secondhand smoke restrictions.8

Experimental studies: attitudes about industry

Two experimental studies examined how an intervention could shape perceptions of the industry. Public perceptions of the tobacco industry were assessed using a controlled before-and-after design, with the movie The Insider as the intervention.42 Post test, subjects viewing The Insider rated tobacco industry executives lower on ethics and honesty and higher on power, held more negative views of industry conduct and showed less acceptance of the industry than controls.42 An RCT investigated effects of perceptions of Philip Morris (PM) as a tobacco company on evaluations of the company’s advertising among undergraduates.66 There was no association between students’ opinion of PM and awareness that it is a tobacco company; however, PM corporate advertisements were rated more favourably by students unaware of this fact.66

Theorising TID

Six studies employed structural equation modelling to theorise TID’s effects. One model suggested knowledge of industry deception leads to mistrust of the industry, which in turn is associated with support for action against the industry and reduced receptivity to advertising.24 Models derived from counter-industry campaign data show that TID exposure leads to negative beliefs about the industry’s conduct, predicting negative attitudes towards the industry; these are associated with lesser progression towards smoking and reduced receptivity to pro-tobacco influences.67, 68 Mistrust of the industry appears to strongly influence negative attitudes towards the industry, which in turn explains significant variability in smoking behaviour, suggesting these campaigns succeed because they resonate with trust-related values.69 Social imagery, perceived tobacco independence and brand equity have also been shown to mediate the relationship between current smoking and exposure to the national ‘truth’ campaign.7072


A robust body of evidence supports TID as an effective population-level tobacco control strategy that contributes to reduced smoking prevalence among youth and young adults, reduced smoking initiation among youth, increased intentions to quit and reduced perceived peer smoking prevalence. Evidence is mixed on TID’s impact on intentions to smoke, youth empowerment and views of the industry and its regulation, but evidence from California suggests TID’s importance as part of a comprehensive social norm change programme.2


Because TID is not yet an established indexing term, we may have missed relevant studies. We reluctantly excluded literature on California’s landmark programme, the first to feature a strong TID component, because published reports merged TID and other social norm change components into a single construct; these could not be separately analysed. However, California programme evaluations suggest that TID has been an important element in increasing quitting, reducing smoking prevalence and increasing support for tobacco control.2, 3, 7376 Heterogeneity in TID interventions and outcome measures did not allow quantitative analyses. Most evidence is from cross-sectional studies, limiting the ability to draw causal conclusions. Most were US studies; national/cultural differences in attitudes towards industry and regulation could limit generalisability.

Interpreting contradictory trials findings

The RCTs’ failure to find an association between TID and intent to smoke may be because the intensity and duration of the interventions were less than in observational studies. Processing of TID-related ads may require additional exposures.40 Experimental studies may not capture TID’s true effectiveness. In Sutfin’s study,40 the only ad type associated with decreased intention to smoke was also the only type that participants reported having previously seen, suggesting that repeated exposures might increase intervention effectiveness.

In addition, trials did not consistently control for understanding of the intervention. In one study, only 34% of participants correctly identified TID ads.40 However, this was not included as a covariate for the outcome of intention to smoke. In larger studies,38, 39 most students recalling ads correctly identified themes.

None of these studies reported absolute numbers of participants expressing intention to smoke. Although Pechmann38, 39 reported that only one of nine ad types tested had a significant effect on smoking intent compared to control, differences between ad types appeared small, making it difficult to determine if there were meaningful differences in proportions of participants expressing intentions to smoke. It may also be that TID interventions are simply less effectively delivered at the individual level.

Research gaps

Many important questions remain unanswered by existing TID-related research. For example, the cost effectiveness of TID programmes relative to other tobacco control interventions remains largely unstudied. A cost-utility analysis of the national ‘truth’ campaign estimated that the campaign recovered the costs of development, delivery, evaluation and litigation, and averted nearly US$1.9 billion in smoking-related medical costs.77 However, the cost effectiveness of such mass media TID interventions compared with other tobacco control interventions is unknown. Similarly, comparative studies are needed to analyse potentially synergistic effects of TID and other tobacco control interventions; whether TID interventions are a necessary component of comprehensive tobacco control; and whether they have an additional effect once other components are in place.

Three existing comparative studies tested the national ‘truth’ campaign against the Philip Morris-sponsored youth smoking prevention programme, ‘Think Don’t Smoke’.27, 35, 36, 50 Whereas the ‘truth’ campaign was associated with an increase in anti-tobacco beliefs and attitudes,27, 35, 36 ‘Think Don’t Smoke’ was associated with an increase in favourable attitudes towards the tobacco industry.35, 36 Similarly, the ‘truth’ campaign was associated with decreased perceived smoking prevalence,50 decreased intentions to smoke and lower rates of smoking initiation,27 while ‘Think Don’t Smoke’ was associated with increased intentions to smoke soon.27 Arguably, an industry-sponsored programme does not offer a fair comparison, so studies aimed at teasing out certain effects of TID as compared with other programme components may be useful. However, TID is also likely to have broader, indirect effects on the policy climate, which constitutes another important area for research.

Most reviewed studies involved mass media interventions; however, TID does not only consist of or work through such relatively expensive interventions, but through wider tobacco control advocacy efforts, such as through earned or unpaid media.7881 It is difficult, if not impossible, to fully and explicitly account for such efforts, which change the public discourse about tobacco use by reframing it away from individual behaviour change towards industry regulation.


Unpacking why TID is an effective tobacco control intervention is complex methodologically and theoretically.82 TID’s effectiveness is likely due to synergies between myriad political and cultural influences that cannot be isolated.83 The evidence suggests that TID is most effectively delivered at the population level and that increased exposure is generally associated with increased effects. Regardless of how TID works, the industry’s aggressive responses suggest that TID passes the ‘scream test’, constituting a threat to the industry’s legitimacy and its continued success in normalising its business, its marketing, and its products.1, 11, 8488 TID may contribute to efforts to ‘directly erode industry power’, making tobacco companies less able to thwart effective tobacco control.89 TID could also enhance public support and political will to counter industry ‘makeover’ efforts and tackle fundamental structural reforms to end the tobacco epidemic.7, 9093

What this paper adds

  • Tobacco industry denormalisation (TID), a focus of successful tobacco control initiatives in the United States and elsewhere, is increasingly regarded as essential to effectively addressing tobacco at the population level. However, TID is not an established indexing term and its effects are challenging to measure. No previous reviews have examined the existing literature on the effectiveness of TID as a tobacco control strategy.
  • This review analyzes the evidence on TID’s effects on smoking prevalence, smoking initiation, intention to smoke, intention to quit, attitudes toward the tobacco industry and its regulation and other outcomes.
  • Robust evidence, summarised here for the first time, shows that TID is an effective tobacco control intervention at the population level.
