Introduction: Health warnings on tobacco packages have been considered an essential pillar in filling the gap of knowledge and communicating the health risks of tobacco use to consumers. Our primary objective was to report the perception of smokers on the textual health warnings already appearing on tobacco packages in Lebanon versus shocking pictures about the health-related smoking consequences and to evaluate their impact on smoking behaviors and motivation.
Methods: A pilot cross-sectional study was undertaken between 2013 and 2015 in five hospitals in Lebanon. Participants answered a questionnaire inquiring about sociodemographic characteristics, chronic respiratory symptoms, smoking behavior and motivation to quit smoking. Only-text warning versus shocking pictures was shown to the smokers during the interview.
Results: Exactly 66% of the participants reported that they thought shocking pictorial warnings would hypothetically be more effective tools to reduce/quit tobacco consumption compared to only textual warnings. Also, 31.9% of the smokers who were motivated to stop smoking reported that they actually had stopped smoking for at least 1 month secondary to the textual warnings effects. A higher motivation to quit cigarette smoking was seen among the following groups of smokers: males (odds ratio [OR] =1.8, P=0.02), who had stopped smoking for at least 1 month during the last year due to textual warning (OR =2.79, P<0.001), who considered it very important to report health warning on cigarette packs (OR =1.92, P=0.01), who had chronic expectoration (OR =1.81, P=0.06) and who would change their favorite cigarette pack if they found shocking images on the pack (OR =1.95, P=0.004).
Conclusion:
Low-dependent smokers and highly motivated to quit smokers appeared to be more hypothetically susceptible to shocking pictorial warnings. Motivation to quit was associated with sensitivity to warnings, but not with the presence of all chronic respiratory symptoms.

Introduction

Tobacco use is a serious and growing health threat worldwide.1 It is the leading cause of preventable death, with around 6 million people dying from tobacco use each year. This number is expected to increase by 20% in 2020.2 Smoking is directly associated with causing about 71% of lung cancer, 42% of chronic respiratory disease and cardiovascular disease.2,3 Several strategies have been considered to reduce the population of smokers. The ban on smoking in public places and increasing the tax on tobacco are currently considered the standards of practice.4 However, additional approaches, such as advising and making people aware of the ill effects of smoking, have also been used.5 In fact, education about smoking-related illnesses has proven to be an effective strategy to raise awareness, encouraging individuals to stop smoking.6 Health warnings on tobacco packages have been considered an essential pillar in filling this gap of knowledge and communicating the health risks of tobacco use to consumers.6 Studies have estimated that smokers are potentially exposed to the warnings over 7,000 times per year. Accordingly, tobacco packages are an essential continuous vehicle to reach out to the target audience, even during the act of smoking.7 The value of warnings on tobacco packages extends to nonsmokers as well, since these portable advertisements become available when the product is used and are often left in public view between uses.8 The World Health Organization’s Framework Convention on Tobacco Control states that “warnings should cover 50% or more of a package’s principal surfaces, and ‘may’ include pictures”.9 Text-only warnings have traditionally been used as the only form of education on tobacco packs, including large text-based warnings. The latter are associated with better effect on decision making regarding tobacco use, compared to standard text-only warnings.10 Text-only warnings are, however, related to the literacy level of smokers, which is reported to be lower than the general public.11 Thus, text-only warnings have been rated by smokers as ineffective and unnoticeable.12,13 On the contrary, pictorial warnings have been proven to be instrumental in reducing the burden of tobacco use. They are self-reflective on health risks, not limited by literacy level, noticeable12,14,15 and are more likely to increase motivation to quit smoking.13,14,16,17

In fact, the use of images may be an effective educational strategy, since pictures improve learning, memory and impact post-message attitudes.1820 Pictorial warnings have not only shown reduced tobacco use and consumption,21 but also increased smokers’ cessation-related thoughts.16,22 Pictorial warning labels also constitute an important source of tobacco risks awareness to nonsmokers.23 This translates into a well-informed society that pressures smokers to quit.

As of 2012, 63 countries/jurisdictions have finalized graphic warning labels requirements as covering 50% or more of the package front and back. Yet, about 40% of countries still have not implemented any warning label policies or require only small warnings that cover <30% of the package.24

In Lebanon, text-based warnings are the only adopted mean on the tobacco packages. Moreover, research on the effect of health warning labels from low- and middle-income countries such as Lebanon is still limited. Our study was thus designed to report the perception of textual health warnings already implemented on tobacco packages in Lebanon versus shocking pictures about health-related smoking consequences and to evaluate their impact on smoking behaviors and motivation.

Methods

Study design

From March 2013 to April 2015, a cross-sectional, questionnaire-based study was conducted. Participants were interviewed in the waiting rooms of respiratory outpatients’ clinics and/or smoking cessation center in five hospitals in Lebanon distributed in the areas of Beirut (n=2), Mount Lebanon (n=1) and North Lebanon (n=2).

Study participants

Eligible participants were current exclusive adult cigarette smokers defined as “currently smoking ≥1 cigarette per day” and visiting the clinic for an ordinary check-up or for an acute respiratory disease including pneumonia, bronchitis or a chronic obstructive pulmonary disease. Patients seeking advice for a smoking cessation program were also eligible to participate. Participants were interviewed in Arabic by a health care provider who was trained to use standardized questionnaires. This study design has been previously described in the Italian population.25

Ethical consideration

We obtained ethical approval from the Institutional Review Board of the Lebanese University for this study. A written informed consent was not needed. Participants were informed about the purpose of the study and their voluntary participation. Their verbal consent was obtained before they were interviewed. Data were anonymous and reported in aggregate.

Study tool and variables

The final version of the standardized questionnaire of the American Thoracic Society was administered in Arabic, the native language of Lebanon; details about the translation process were presented in a study conducted by Waked et al.26 Sociodemographic characteristics including age categorized into <45 and ≥45 years25 and gender were collected. Chronic respiratory problems were assessed using the following definitions: “Chronic respiratory disease diagnosed by a doctor, reported chronic cough, reported chronic phlegm, chronic bronchitis defined as cough and phlegm for >3 months per year since 2 years,27 cough and phlegm for >3 weeks and chronic wheezing”.

Smoking behavior details included the number of cigarettes smoked per day and the number of years of smoking cigarette. For the number of cigarettes smoked per day, responses were categorized into 1–9, 10–25 and >25 cigarettes per day.25 The number of years of smoking for each participant was categorized into <6, 6–15, 16–25 and >25 years of smoking, with the intention to compare it to the Italian study.25

Smoking dependence was assessed using Fagerström scale with ≥5 translated into high dependency.25,28 Also, the Mondor scale was used to evaluate the motivation to quit smoking, with a score of >12 meaning high motivation to quit.29

We also investigated the actual effect of currently used textual warnings on quitting smoking for at least 1 month during the last year and the reduced amount of cigarette smoked daily due to these warnings, by asking two questions:

  1. “Have you ever stopped smoking for at least 1 month after reading the textual warnings on the cigarette package?”
  2. “Are you or have you been influenced by the health warnings in a way that lead you to (reduce the number of cigarettes you smoked daily)?”

Furthermore, we examined the importance of reporting health warnings on cigarette packages and the influence of these warnings on increasing the curiosity of people to seek the help of a specialist (doctor or pharmacist) to stop smoking, by asking two questions:

  1. “Do you consider it important to report the health warnings about tobacco consumption on cigarette packs?”25 A lot, enough, poor, no
  2. “Have the health warnings increased the curiosity or the desire to be better informed or to be helped to give up smoking?”25 A lot, enough, poor, no.

Finally, after showing the participants a group of shocking pictures about the negative smoking consequences on some body organs (black teeth, dirty lungs and so on),30 two items were used to evaluate quantitatively the packaging perception related to its hypothetical impact for smoking cessation or reduction:

  1. “If these shocking images were used on tobacco boxes, would they have greater effect than simple warning text currently used?” Yes/no
  2. “If your favorite cigarette brand decides to change its look by using these pictorial warnings on tobacco packaging, would you think of buying another cigarette brand?” Yes/no.

Sample calculation

This pilot trial aimed to recruit 369 smokers. Sample size calculation was done with a 95% confidence level and a precision of 5%. The mean percentage of Lebanese adults who have ever smoked cigarettes is around 60%; 31 approximately 62% of the smokers in Italy perceived that warnings with shocking pictures are more effective in reducing/quitting tobacco consumption than text-only warnings.25 Accordingly, we expected that around 60% of the population of cigarette smokers in Lebanon considered using shocking pictures to have greater effect than the simple warning currently used.

Statistical analysis

The statistical analysis was carried out using IBM-SPSS version 19 software for Windows Release (IBM Corp. released in 2010 IBM SPSS Statistics for Windows, Version 19.0; IBM Corporation, Armonk, NY, USA). Categorical data were shown as absolute frequencies and percentages. Continuous data were presented as median (interquartile range [IQR] = P25–P75). The dichotomous nicotine dependence and motivation to stop smoking variables were compared between groups using the chi-square test.

A multivariable logistic regression analysis was carried out in order to assess the impact of the pictorial warning by using as outcome the two questions concerning the impact of the pictorial warnings. The independent factors included in the models were the following: gender, age groups (<45 years), nicotine dependence (high/low), motivation to stop smoking (high/low) and chronic respiratory symptoms. In addition, another multivariable logistic regression was performed using the motivation to quit as a dependent variable, whereas gender, age groups, dependence scale, textual/pictorial perception and chronic respiratory symptoms were used as independent variables in the model. Furthermore, we performed a multivariable logistic regression using as outcome a reduction in the number of cigarettes smoked daily with the following independent variables: age, gender, Mondor scale (motivation to quit), scale of dependence, textual/pictorial perception and chronic respiratory symptoms. The odds ratios (ORs) adjusted for the covariates with their 95% confidence interval were indicated. The Hosmer and Lemeshow test was applied to estimate the goodness of fit for each model. The statistical significance was set at a P-value <0.05.

Results

Sample description

In total, data were collected from 382 cigarette smokers with the response rate of 92%, ranging from 88% to 96% in different collection centers. Study participants were mainly males (61%). Around 49.2% were <45 years. The mean age was 44.52 years (standard deviation [SD] =14.1; Table 1).

Table 1 Description of the sample of cigarette smokers (N=382)

Concerning the smoking habits of smokers, 52.4% of our participants indicated that they smoked around 10–25 cigarettes a day, compared to 38% who reported smoking >25 cigarettes per day and <10% reported smoking <10 cigarettes daily. The median duration of cigarette tobacco use was 20 years (IQR =10–31), and the median age of smoking first cigarette was 18 years (IQR =16–21).

In regard to the Fagerström scale, around 69% of our participants were classified as highly dependent on nicotine. Furthermore, 53.1% were unfavorably motivated to quit, based on Mondor scale.

Ninety one percent of respondents were aware of the health consequences of smoking. Most of them reported that the short-term concerns from tobacco consumption were breathlessness (71.7%), bad breath (63.4%), bad smelling cloths (60.5%) and yellow teeth (58.6%).

Warning labels recognized effects

Currently used textual warnings on smoking habits were reported to have actually triggered a smoking cessation trial for at least 1 month and a reduction in the number of cigarettes smoked a day in 21% and 19.1% of cigarette smokers, respectively. Around 12% of the participants reported that they stopped smoking when they woke up in the morning or after drinking coffee due to the textual warnings. Furthermore, 66% of the participants reported that they thought shocking pictorial warnings would hypothetically be more effective tools to reduce/quit tobacco consumption compared to only textual warnings and the graphics were the most preferred (54.7%) compared to only-text warning (4.7%) and the association of text/pictures (20.7%). Also, the findings indicate that 48.4% of the participants would change their cigarette brand if the smoking health damage warnings of that brand would change to shocking pictures (Table 1).

Warning labels, gender and age groups

Women seemed to be more affected by the physical effects of smoking, particularly the appearance of wrinkles and skin spots (47%, P=0.002 and 28.5%, P=0.01, respectively). More women reported that currently used health warnings increased their desire to be well informed and/or and to give up on smoking, compared to men (19.4% versus 16.7%). Women were more inclined to cease from buying their favorite cigarette pack in case there was pictorial smoking awareness on their cigarette package (59% of females versus 45% males, P=0.03; Table 2).

Table 2 Description and comparison of cigarette smokers by gender and age group

On the other hand, males reported being more worried about their physical fitness getting affected as a consequence of having smoking-related shortness of breath (80.6% versus 66%, P=0.002). They highlighted the importance of reporting health warning about tobacco consumption on cigarette packs (50% versus 39.6%, P=0.02).

Table 2 also shows the comparison by age groups. No significant differences between young and old smokers were found with respect to health warnings, except for yellow teeth (56.2% versus 66.3% for ≤45 years, P=0.04).

Warning labels, dependence and motivation to quit smoking

The analysis showed that smokers who were motivated to stop smoking reported to actually having stopped smoking for at least 1 month secondary to the textual warnings effects, compared to the group of smokers who were not motivated to stop smoking (31.9% versus 14.3%, P<0.001; Table 3). Furthermore, the motivated group reduced the daily consumption of cigarettes (25.8% versus 15.3%, P=0.01) and/or refrained from smoking after a cup of coffee (19% versus 6.9%, P<0.001) after seeing the textual warning. The same group considered the current textual health warnings reported on cigarette packages essential to increase the awareness and motivation to reduce/quit tobacco consumption (59.5% versus 35%).

Table 3 Description and comparison of cigarette smokers by motivation score and dependence score

Participants with high motivation reported more frequently that pictorial warnings would hypothetically be more effective communication tools to reduce/quit tobacco consumption, compared to currently used only-textual warnings (76.7% versus 62.6%, P=0.004). They would be most effective to fight smoking (60.1% versus 54.7%). Furthermore, highly motivated participants would not buy their favorite cigarette brand if there were printed images on the health effects of smoking (59.5% versus 43.3%, P=0.008; Table 3).

On the contrary, the group of smokers with high nicotine dependence reported that they were less influenced by the current health warnings on cigarette packs (daily number of cigarettes smoked: 17.1% versus 26.3%, P=0.04) and that they were more resistant to changing their smoking habits (9.9% versus 17.5%, P=0.04). Moreover, the highly dependent smokers reported that health warnings did not affect their desire to be well informed and to give up on smoking, compared to low-dependent smokers (63.5% versus 53.5%, P=0.03). The same group reported being less impressed by the hypothetical impact of shocking images (64.7% versus 78.1%, P=0.01) and did not consider the health labels as crucial elements to increase the awareness and/or the motivation to quit (43.7% versus 50.9%, P=0.008; Table 3).

Effects of chronic respiratory symptoms

The presence of chronic health symptoms was not statistically associated either with the motivation to quit smoking or with the hypothetical effect of shocking images/textual warnings on tobacco packs on quitting/reducing cigarettes and the switching of the favorite brand (Table 4).

Multivariable analysis

Multivariable logistic “regression 1” analysis showed that shocking pictorial warnings were significantly two times more hypothetically effective in reducing the smoking behavior in motivated and lower dependent smokers (OR =2, P=0.004 and OR =1.88, P=0.018, respectively). On the other hand, another multivariable analysis “regression 2” revealed significantly more females and more motivated smokers changing the favorite cigarette brand due to the inclusion of shocking images (OR =1.92, P=0.004 and OR =2.08, P=0.001, respectively; Table 5).

Indeed, Table 5 shows the multivariable logistic analysis of the motivation to quit “regression 3”. It indicates a significantly higher motivation to quit cigarette smoking among male smokers (OR =1.80 for males versus females, P=0.02), who had stopped smoking for at least 1 month during the last year due to the textual warning (OR =2.79, P<0.001), who considered it very important to report health warning on cigarette packs (OR =1.92, P=0.01), who had chronic expectoration (OR =1.81, P=0.06) and who would change their favorite cigarette pack if there were shocking images on the pack (OR =1.95, P=0.004).

Table 6 shows the multivariable analysis of the reduction in the number of cigarettes smoked daily due to the warnings; we found a higher reduction among males (OR=1.86, P=0.04), smokers aged ≥45 years (OR =2.2, P=0.007), smokers who were motivated to quit (OR =2.13, P=0.007) and low-dependent smokers (OR =1.88, P=0.03). Indeed, a higher reduction was seen among smokers who had cough and expectoration for >3 months/year since 2 years (OR =2.7, P=0.002), whereas it was inversely associated with chronic wheezing (OR =0.43, P=0.06).

Discussion

This study assessed the Lebanese adult cigarette users’ response to the textual health warnings, covering only 40% of the two primary surfaces of cigarette containers, and their perception of the future implementation of graphic warnings on packages. Similar to a study done on Canadian students,32 the majority of our study participants acknowledged that pictorial warnings would hypothetically be more effective than only-text warnings in reducing/the attempt to quit smoking. This is also supported by various other reports.25,3339

Findings from both experimental and population-based studies demonstrated that pictorial health warnings are more likely to be noticed and read by smokers than text-only warnings and that they are associated with greater motivation to quit smoking.18 Furthermore, most of the proposed labels by Cameron et al enhanced fear-related reactions about the health consequences of smoking and also enhanced the motivation to quit, relative to text-only labels.40 Experimental research on cigarette warnings has also found that picture-based warnings are more likely to be rated as more effective than text-only warnings on a range of outcomes, including being a deterrent for new smokers and a means to increase cessation among current smokers.41,42 In addition, the inclusion of pictures on one side of the cigarette pack increased smoking avoidance in France and the UK.43 Prominent health warnings that cover a significant proportion of the package, particularly pictorial warnings, have the potential to undermine a brand’s appeal and the impact of package displays at retail outlets.4449

Interestingly, our study also revealed that females were significantly more affected by the impact of smoking on the appearance of wrinkles, hair loss and skin spots. In fact, Mannocci et al highlighted this concept and showed that women were significantly more susceptible to the immediate consequences of smoking (appearance of wrinkles) and more prone to switch to light cigarettes.38 It is further proven that women judged the pictorial warnings as more aversive than men; consequently, the more aversive a warning, the more it is perceived as effective against smoking.50,51 Furthermore, Mannocci et al showed that females were more affected by the shocking images in reducing tobacco consumption.25 More than 50% of female smokers reported they would change their favorite cigarette brand if the manufacturing company implements pictorial shocking warnings on the cigarette pack, which is in line with another study.25

Concern over health risks is the most common motivation for quitting smoking.52,53 Health warnings on tobacco packages are among the most prominent interventions to convey the health risks of smoking. Previous studies have demonstrated that smokers with greater knowledge of the health risks of smoking were more likely to intend to quit and were more successful in their quit attempts.54,55 In our study, the health warning labels increased the curiosity of around 20% of females to be better informed or be helped to stop smoking. Similarly, in a study by Koval et al, female current smokers were more likely to think about quitting smoking.56 Furthermore, males were significantly more affected by the health warnings related to physical fitness ability, particularly shortness of breath. According to several studies,22,25,34,38,57,58 younger people are more sensitive to warnings; on the other hand, Hammond et al found that older smokers rated warnings as more effective.34

However, in our sample, there was no statistically significant difference between younger and older smokers in rating the efficacy of different types of warnings; meanwhile, both considered shocking pictorial warnings have greater effect than simple warning text currently used (68.6% versus 69.1% for >45 years and ≤45 years, respectively). Our results were similar to those reported by Hammond et al where the interaction between age group and graphic internal versus graphic external was not significant.34

A greater hypothetical effect of shocking images on cigarette boxes was significantly associated with lower nicotine dependency levels of smokers among the present study population. Furthermore, the lower dependence smokers considered it significantly important to report health warnings on packages. A statistically significant higher hypothetical effect of the shocking pictures was found among low-dependent smokers in our study, consistent with another research.25 Moreover, a statistically significant better impact on more motivated smokers was found, which was similar to the results of Mallikarjun et al where a higher sensitivity to pictorial warning labels was significantly associated with lower dependency scale.59 Loeber et al suggested the use of pictorial health warnings as an effective public health strategy to reduce the inclination toward cigarette packages of light smokers (<20 cigarettes/day).60 Moreover, levels of perceived effectiveness of health warnings have been found to be higher among low-dependent smokers and less-committed smokers.61 Finally, a higher decrease in the number of cigarettes smoked daily and a reduction of their smoking habits due to the textual warnings were found among lower dependence smokers. Consequently, this study highlighted that the exposure of smokers with low nicotine dependence to tobacco warning labels helps educating them about the health risks of tobacco smoking and subsequently guides them to quit smoking. Sequentially, in our opinion, later this could create a dilemma: “Is it the high nicotine dependence that induces insensitivity to pictorial and written warnings or the insensitivity to such warnings which is a phenotype that induces high addiction?” Subsequently, this could be explained by the reverse causality concept. Concerning the motivation to quit variable, our study showed that the group highly motivated to quit cigarette smoking considered that the warnings with shocking pictures would hypothetically have significantly greater effect than the textual warnings used alone on the reduction/quitting behavior. These findings are consistent with a report showing that vivid pictures that convey high threat are some ways in which the labels could be designed to enhance perceived susceptibility.62

Around 60% of the highly motivated participants considered health warnings on cigarette packages to be very important, compared to 35% of the unmotivated individuals. Indeed, around 32% stopped cigarette smoking for at least 1 month due to the currently used textual warning, compared to 14% of unmotivated smokers. This has been demonstrated in other studies where participants who had made a quit attempt were most motivated by the labels about their own risks of smoking.62 In Italy, reporting negative labels concerning the risk on the health was found to highly influence the subgroup of cigarette smokers who were highly motivated to quit.25

On the other hand, research has shown that motivation to quit is associated with making quit attempts.63,64 Usually, one approach to increase motivation in order to change behaviors such as quitting smoking is theorized by the extended parallel process model, which assumes that individuals are motivated to act through fear if they perceive a high level of risk from their engagement in an unhealthy behavior, specifically that they are susceptible to negative consequences such as chronic health symptoms.65 However, in our study, having chronic health symptoms was sometimes inversely correlated to the motivation to quit (OR <1); only chronic expectoration showed a positive association with motivation to quit. This might be due to the smokers being unaware of the danger of tobacco use on health. Therefore, tobacco control messaging that aims to increase smokers’ motivation to quit should contain both threat and efficacy messages to increase the risk perceptions and efficacy beliefs. Labels have largely relied on fear appeals to increase smokers’ risk perceptions using depictions of the negative effects of smoking.18 The threat portrayed in a message – characterized by susceptibility to health conditions – intrinsically motivates action through fear by increasing individuals’ perceptions of their risk65 and consequently promotes cessation-related attitudes and behaviors.18,34 Alarmingly, threat messages might not appear to be sufficient to motivate changing behavior in our country, in which smoking risk might be considered lower than other risks, such as the political situation and the actual situation of Lebanon in the Middle Eastern countries. Such messages must be accompanied by professional and social support, motivation sessions and information about the centers where they can seek help.

Concerning the influence of chronic bronchitis (cough and phlegm for >3 months/years since 2 years) on the motivation to quit with an OR =0.52, this result might be explained by the fact that people who have more episodes of cough and phlegm (chronic bronchitis) are the ones who consider that smoking does not affect the respiratory system; therefore, they continue to smoke and are not motivated to quit cigarette smoking.

Moreover, we noticed that the motivation to quit as well as a reduction in the number of cigarettes smoked daily were frequently observed among male smokers, which is similar to the results of Osler et al66 and Hymowitz et al67 indicating that male gender was a predictor of smoking cessation. On the contrary, McAllister et al showed that females considered seriously cutting down the number of cigarettes they smoked compared to males, but males were more likely to have intentionally quit smoking for at least 1 day within the past year.68 Indeed, cutting down the number of cigarettes smoked daily may reduce the harm caused by smoking and may also be a step toward stopping smoking completely.69

Limitations

There are some limitations that should be considered in interpreting the findings from this study. First, the sample may be described as a nonrandom sample because respondents were only randomly approached at hospital places, including a center for smoking cessation, rather than being randomly selected from a sampling frame. Therefore, the sample may be somewhat biased towards more sensitive categories with respiratory problems. Another important limitation is total reliance on self-report to assign subjects to the relevant smoking status. Due to social, demographic and environmental desirability potentials associated with smoking behavior, some smokers might have denied or underreported their actual smoking status. Furthermore, the perceptions and attitudes of the individuals in this study may not necessarily be generalizable to all individuals within Lebanon. Therefore, larger population-based studies should be conducted in the future to confirm our findings. Moreover, our cross-sectional study evaluated the noncausal association between warning health labels and smoking status; therefore, we are conducting a longitudinal prospective study to determine the impact of pictorial warnings on smoking intentions and behaviors, which is to be published in the near future.

Conclusion

The present study is, to our knowledge, the first study conducted in Lebanon that evaluates the perception of adult smokers on the effectiveness of textual versus pictorial warnings on cigarette tobacco packages. In our study, low-dependent smokers and highly motivated to quit smokers appeared to be more hypothetically susceptible to shocking pictorial warnings. Motivation to quit was associated with sensitivity to warnings, but not with the presence of all chronic respiratory symptoms. Finally, pictorial warning is a tiny part of the global awareness campaigns for decreasing tobacco smoke. It might be targeting a small part of smokers, whereas another phenotype needs a different message as an incentive to quit smoking.
