Waterpipe tobacco smoking prevalence is increasing around the globe despite current evidence that smoke emissions are toxic and contain carcinogenic compounds.
To evaluate current health warning labelling practices on waterpipe tobacco products and related accessories.
All waterpipe tobacco products, as well as waterpipe accessories, were purchased from Lebanon and a convenience sample was obtained from Dubai (United Arab Emirates), Palestine, Syria, Jordan, Bahrain, Canada, Germany and South Africa.
Of the total number of waterpipe tobacco products collected from Lebanon, the majority had textual health warning labels covering on average only 3.5% of total surface area of the package. Misleading descriptors were commonplace on waterpipe tobacco packages and related accessories.
There are no WHO FCTC compliant waterpipe-specific health warning labels on waterpipe tobacco products and related accessories. Introducing health warnings on waterpipe tobacco products and accessories will probably have worldwide public health benefits.
The prevalence of waterpipe tobacco smoking is increasing.1 Where once this mode of smoking was confined mostly to the Eastern Mediterranean Region (EMR), it is now becoming more common around the globe, particularly among young people.2–7 In Lebanon, 29.6% of school students were currently smoking waterpipes in 2004.8 In Latvia and Slovenia in 2007, 76.3% and 60.9% of school students, respectively, reported current waterpipe use (defined as less than once a week) with 3.0% and 6.3% reporting daily use.5 In Pittsburgh, USA, in 2007, 40.5% of university students reported ever smoking waterpipes.9
Waterpipe tobacco smoking has existed historically in different cultures with various names including hookah, huqqa, arghile, narghile, hubble bubble, goza and boori. The waterpipe apparatus consists of a head, body, water ball and hose (figure 1). The tobacco is placed on the head which in turn is connected through the body to a water ball. A piece of charcoal is placed on top of the tobacco to heat it. Various accessories are used when smoking waterpipes (table 1).1 Two types of waterpipe tobacco are found on the market, the fruit-flavoured tobacco, referred to here as moassel, is tobacco mixed with molasses as a primary ingredient. Moassel tobacco gives off the aroma of burned sugar when smoked. The other kind of tobacco is called ajami and is the more traditional form of unflavoured tobacco, and gives off a harsher smell of tobacco when smoked.10
Current evidence on waterpipe smoke chemistry is based on results from experiments with a standard waterpipe smoking machine.11 Although waterpipe tobacco smoking is often perceived to be safer than cigarette smoking,12 smoke machine experiments have shown that waterpipe smoke delivers in a single session as much tar as an entire pack of cigarettes.13 It also contains nicotine 10 13–15 and other toxic and carcinogenic compounds such as carbon monoxide, formaldehyde, polyaromatic hydrocarbons, arsenic and lead.13 16 17 In addition to toxicants issuing from the tobacco, waterpipe users are also exposed to carcinogens and carbon monoxide emitted from the charcoal.18 Although studies are still needed to assess long-term health effects of waterpipe smoking and potential difference between cigarettes and waterpipes, current evidence suggests that waterpipe smokers may be subject to similar health risks as those incurred by cigarette smoking, including cancer, heart and respiratory diseases.7 19 Other health risks include the transmission of infectious diseases, such as tuberculosis, owing to sharing of the waterpipe hose, a common practice in social gatherings.20
The World Health Organization Framework Convention on Tobacco Control (WHO FCTC) covers a range of tobacco control policies.21 The FCTC obliges parties to the treaty to comply with its provisions. Article 11 of the FCTC, which specifically addresses packaging and labelling of tobacco products, prescribes a rotating series of health warnings that should cover at least 50% (or must cover at least 30%) on average of the front and back of the package. The treaty also encourages the use of graphical rather than textual warnings. A key aspect of Article 11 is a ban on misleading descriptors; the article text states that ‘tobacco product packaging and labelling do not promote a tobacco product by any means that are false, misleading, deceptive or likely to create an erroneous impression about its characteristics, health effects, hazards or emissions, including any term, descriptor, trademark, figurative or any other sign that directly or indirectly creates the false impression that a particular tobacco product is less harmful than other tobacco products. These may include terms such as ‘low tar’, ‘light’, ‘ultra-light’, or ‘mild’.
Although the WHO FCTC covers all tobacco products, its articles are in general more tuned to cigarettes in comparison to other modes of tobacco smoking, such as the waterpipe. Recently guidelines for Article 11 were presented at the conference of the parties meeting in Durban, South Africa in November 2008. Although not legally binding, the guidelines stated the need to have ‘different health warnings and messages for different tobacco products, such as cigarettes, cigars, smokeless tobacco, pipe tobacco, bidis and water pipe tobacco, to better focus on the specific health effects related to each product.’22
This paper presents an evaluation of current health warning labelling practices of waterpipe tobacco products and accessories based on a representative sample purchased from retail outlets in Beirut, Lebanon, and a small convenience sample of products purchased from other countries. All countries in which samples were acquired have ratified the FCTC (except Bahrain which has indicated acceptance).
A list of all waterpipe tobacco brands available on the Lebanese market was obtained from the Lebanese Tobacco Monopoly, the Regie, assigned the sole responsibility for procurement, manufacturing and selling of cigarette and waterpipe tobacco in Lebanon.23 Using the list provided by the Regie as a reference, all tobacco products were purchased from major supermarkets and specialised stores in the Greater Beirut area. Waterpipe accessories, such as filter tips, mouthpieces, aluminium foil and charcoal, manufactured especially for waterpipe preparation were also purchased. Once no new tobacco products or accessories were located, field visits were discontinued.
In addition, to assess whether waterpipe products sold elsewhere differed from those sold in Lebanon, we obtained a convenience sample from Dubai (United Arab Emirates), Palestine, Syria, Jordan, Bahrain, Canada, Germany and South Africa.
All packs of collected products were analysed according to the following variables:
In total, 74 waterpipe tobacco products (of 25 different brand names) were collected and distributed as follows: 39 different packs from Lebanon (37 moassel and two ajami) and the rest of the products collected from other countries were all moassel as follows: eight from Dubai, three from Palestine, four from Syria, six from Jordan, 10 from Bahrain, two from South Africa, one from Canada and one from Germany.
The most common weight of waterpipe tobacco packs were 50 g and 250 g. The most common mode of packaging was cardboard boxes of various sizes, but other products were contained in jars and tin cans. The most common flavours of waterpipe tobacco were apple, grape, lemon, cherry, melon, mint, strawberry, mango, peach, banana, pineapple, mixed fruits, minted lemon, bubble gum, chocolate, licorice and Red Bull (the energy drink).
Of the 39 waterpipe tobacco products collected in Lebanon, 90% had health warning labels on the outer package only whereas two did not have any label at all. Of the 35 waterpipe tobacco products collected from other countries, 91% had health warning labels on the outer package only, and two products had no label at all.
The same textual warning as that found on cigarette packs was found on all the waterpipe tobacco products purchased from Lebanon. The health warning message labels varied on packages obtained from Palestine, Germany and South Africa. In Palestine, two of the health warning messages addressed cigarette smoking rather than waterpipe tobacco smoking (see box 1).
In Lebanon, 77% of the waterpipe tobacco products had their health warning labels in Arabic, the official language. In other countries, 6% of the waterpipe tobacco products had their health warning labels in Arabic only. The second language used was English.
All warnings were in the form of textual messages. For products obtained from Lebanon, 87% had warnings labels on the side of the pack with no special demarcation. The textual labels on packages covered on average 3.5% of total surface area of the package.
Of those packages obtained from other countries, 74% had the health warning labels on the side. Only those from Palestine and Germany had health warning labels covering up to 30% of front and back. Health warning labels on packages obtained from Dubai, Bahrain, Jordan and Syria were comparable in size to the ones found on the Lebanese market (on average making up to 3.5% of total surface area of the package) (table 2).
Seventy-seven per cent of packages collected from Lebanon stated the percentage of tar as 0.0%, 28% stated the percentage of nicotine as 0.5% and 36% stated the percentage of nicotine as 0.05%. Among products obtained from other countries, 77% of the products also stated the percentage of tar as 0.0%, 54% stated the percentage of nicotine as 0.5% and 26% stated the percentage of nicotine as 0.05% (figure 2). The above findings clearly indicate that ingredient disclosure is erroneous and should be regarded as misleading under Article 11.
Other qualitative descriptors (such as ‘Premium taste’, ‘For adults only’, ‘Ultra lights’, ‘Light Virginia Tobacco’), which were also misleading, were identified on 27% of the packs. On the packages collected from Lebanon and other countries, on average across all waterpipe tobacco packs, qualitative misleading descriptors occupied overall less than 1% of the total surface area.
In total, 35 waterpipe-related accessories (all different brands) were collected as follows: eight different types of filters were collected (five filter mouthpieces, one filter within the water and two filters designed to be placed between the hose and the head); four types of mouthpieces; seven types of aluminium foil; and 16 types of charcoal were collected from Lebanon, except for one charcoal brand from UAE.
None of the aluminium foils, mouthpieces and charcoal included any warning labels. Out of eight filters purchased, only three had a generic health warning label as the one found on the waterpipe tobacco in Lebanon. These were placed on the side or back of the pack, not on the unit packs.
On average across all packages measured, qualitative misleading descriptors occupied 17% of the total surface area of waterpipe-related accessory packages. On the filters, such descriptors covered on average up to 33% of the pack surface area. With regard to the rest of the waterpipe accessories, misleading qualitative descriptors covered on average 2%, 23% and 12%, of the surface area of aluminium foil, mouthpieces and charcoal packages, respectively (see box 2).
When at least one requirement of Article 11 was not met (excluding pictorials since they are considered optional as per the FCTC), a country was categorised as non-compliant (table 2). Although Lebanon ratified the WHO FCTC in 2005, all waterpipe tobacco products were non-compliant. Other countries from which waterpipe tobacco products were obtained, were also non-compliant. Furthermore, the research showed that waterpipe-related accessories and almost all waterpipe tobacco products (except for those obtained from Canada, Germany and Palestine) contained misleading qualitative descriptors that also need to be regulated as stipulated by guidelines of Article 11 of the WHO FCTC.22 Misleading descriptors provide erroneous information and give users a false impression of safety.10 13 24 Alarmingly, the majority were labelled as having 0% tar content.
Established evidence that health warning labels on cigarette packages increase awareness of health risks among smokers and non-smokers and decrease consumption25 outlines the need to include health warnings on waterpipe tobacco products and accessories. Requiring health warning labels on waterpipe tobacco products and accessories is potentially more challenging than on cigarette packages because packaging often comes in different shapes and sizes. Moreover, waterpipe tobacco smoking takes place at home (where the smoker prepares his/her own waterpipe) as well as in restaurants and cafés, where the consumers do not see the waterpipe tobacco packs, yet are exposed to the related accessories. Thus, development of waterpipe-specific guidelines needs to take into consideration issues such as placement (on package of tobacco, on apparatus, accessories and menus in cafés or restaurants), size, type of pictorial and health warning message.
Warning labels also need to address some of the misperceptions that people have about waterpipe tobacco smoking such as the water in the bowl filters the toxicants, or the sweet fruity smell of the moassel tobacco smoke as harmless.7 This may be exaggerated by our observation that some warnings on waterpipe tobacco referred to cigarette smoking rather than tobacco smoking being harmful. The authors have discussed a more recent phenomenon of marketing waterpipe-related accessories using environmental and health safety claims,26 a strategy that in turn would require tailoring appropriate messages countering such misconceptions. Thus in addition to warning labels addressing health consequences, others could address social, economic and environmental impact of waterpipe tobacco smoking.
Given emerging evidence on the increase in prevalence of waterpipe tobacco smoking among the population globally,1–6 27 the introduction of policies requiring health warnings on waterpipe tobacco products and accessories will probably have resounding public health implications worldwide. A more thorough evaluation of health warning labelling practices of waterpipe tobacco products and accessories in other FCTC ratifying countries is still needed as the study here mostly focused on Lebanon. Also more rigorous studies to test appropriateness of various images, impacts of health warning messages and their practical and logistic application in different settings are needed. The authors provide here a few examples that they developed of possible health warnings for waterpipe tobacco packages and related accessories based on preliminary research (figure 3).
