Abstract
A prospective online study, consisting of 203 participants ages 18 and older who smoked waterpipe (hookah) within the last 30 days, examined how brief messaging about harms of burning charcoal to heat waterpipe tobacco (shisha) influenced knowledge of toxicants released by using charcoal and perceived harms of using charcoal. Participants were randomized to either a control or to an educational arm that reviewed toxicants released by burning charcoal and the health consequences. Participants in the educational relative to the control arm perceived charcoal as more harmful, were more knowledgeable of toxicants released by burning charcoal, and expressed a stronger desire to quit. Effects were sustained a week later. Brief messages about the harms of burning charcoal were effective and may be used to educate the public about the harms of waterpipe tobacco smoking.

Abstract
This work provides insights on waterpipe tobacco and waterpipe charcoal as potential sources of environmental toxicants. Selected harmful and potentially harmful constituents (HPHCs) from ten U.S. commercial waterpipe tobacco filler products (before and after electric heating) and five waterpipe charcoal products (before and after burning) were investigated. The differences in quantities of HPHCs between the evaluated products appear to be affected by raw material properties and/or the manufacturing processes involved in product production. Trace metal quantities in waterpipe tobacco and charcoal products were observed after heating or burning conditions compared to unheated or unburned conditions, which could impact the environment through the generation of toxic tobacco product waste. This study demonstrates that waterpipe tobacco and waterpipe charcoal contain substantial quantities of benzo[a]pyrene (B[a]P) and trace metals (i.e., selenium, arsenic, cadmium, chromium, cobalt, lead, nickel) before use and that extensive and varied changes in trace metal quantities take place as a result of heating, and more studies are needed to estimate the magnitude of the environmental impact of waterpipe tobacco use.

Abstract
Background: The rates of tobacco use, including cigarette and waterpipe smoking, are surging in the Eastern Mediterranean region. The use of these products causes nicotine dependence that makes even short-term tobacco abstinence difficult due to aversive symptoms. During the daytime fasting of the month of “Ramadan”, people accept significant disruption in regular activities, including tobacco smoking. Thus, daytime during Ramadan (before sunset) is likely associated with abstinence symptoms emerging among tobacco smokers. We assessed this hypothesis by measuring tobacco/nicotine abstinence symptoms and craving among smokers of cigarettes or waterpipes during Ramadan. Methods: A cross-sectional survey-based study was conducted on a convenience sample of adults. Participants were assessed for general information about tobacco smoking, dependence, and nicotine desire or craving, and withdrawal symptoms using the Minnesota Nicotine Withdrawal Scale (MNWS) and the Tiffany-Drobes Questionnaire on Smoking Urges. Results: The study sample included 632 exclusive cigarette smokers and 161 exclusive waterpipe tobacco smokers. After fasting and abstaining from tobacco during the day, approximately 75% of cigarette smokers and 20% of waterpipe smokers reported smoking within the first 30 minutes. In addition, 10% of cigarette smokers and 30% of waterpipe smokers reported smoking within the first 60 minutes. Regarding smoking urge, no significant difference was found between cigarette and waterpipe smokers. For nicotine craving and withdrawal, significant differences between cigarette and waterpipe smokers were found when comparing mean scores for each of the following items: (i) urge to smoke, (ii) craving nicotine, (iii) hunger, (iv) desire for sweets, and (v) depression/feeling blue (P-values < 0.05). Conclusion: This study provided evidence from the month of Ramadan that waterpipe smoking is associated with abstinence-induced smoking urge and withdrawal symptoms that are comparable to cigarette smoking. More interdisciplinary research must be focused on developing interventions to reduce tobacco smoking, including waterpipe.

Abstract
Epidemiology studies link cigarillos and shisha tobacco (delivered through a hookah waterpipe) to increased risk for cardiopulmonary diseases. Here we performed a comparative chemical constituent analysis between 3 cigarettes, 3 cigarillos, and 8 shisha tobacco products. The potency for genotoxicity and oxidative stress of each product's generated total particulate matter (TPM) was also assessed using immortalized oral, lung, and cardiac cell lines to represent target tissues. Levels of the carcinogenic carbonyl formaldehyde were 32- to 95-fold greater, while acrolein was similar across the shisha aerosols generated by charcoal heating compared to cigarettes and cigarillos. Electric-mediated aerosol generation dramatically increased acrolein to levels exceeding those in cigarettes and cigarillos by up to 43-fold. Equivalent cytotoxic-mediated cell death and dose response for genotoxicity through induction of mutagenicity and DNA strand breaks was seen between cigarettes and cigarillos, while minimal to no effect was observed with shisha tobacco products. In contrast, increased potency of TPM from cigarillos compared to cigarettes for inducing oxidative stress via reactive oxygen radicals and lipid peroxidation across cell lines was evident, while positivity was seen for shisha tobacco products albeit at much lower levels. Together, these studies provide new insight into the potential harmful effects of cigarillos for causing tobacco-associated diseases. The high level of carbonyls in shisha products, that in turn is impacted by the heating mechanism, reside largely in the gas phase which will distribute throughout the respiratory tract and systemic circulation to likely increase genotoxic stress.

Abstract
Electronic cigarette usage has spiked in popularity over recent years. The enhanced prevalence has consequently resulted in new health concerns associated with the use of these devices. Degradation of the liquids used in vaping have been identified as a concern due to the presence of toxic compounds such as aldehydes in the aerosols. Typically, such thermochemical conversions are reported to occur between 300 and 400 °C. Herein, the low-temperature thermal degradation of propylene glycol and glycerol constituents of e-cigarette vapors are explored for the first time by natural abundance 13C NMR and 1H NMR, enabling in situ detection of intact molecules from decomposition. The results demonstrate that the degradation of electronic nicotine delivery system (ENDS) liquids is strongly reliant upon the oxygen availability, both in the presence and absence of a material surface. When oxygen is available, propylene glycol and glycerol readily decompose at temperatures between 133 and 175 °C over an extended time period. Among the generated chemical species, formic and acrylic acids are observed which can negatively affect the kidneys and lungs of those who inhale the toxin during ENDS vapor inhalation. Further, the formation of hemi- and formal acetals is noted from both glycerol and propylene glycol, signifying the generation of both formaldehyde and acetaldehyde, highly toxic compounds, which, as a biocide, can lead to numerous health ailments. The results also reveal a retardation in decomposition rate when material surfaces are prevalent with no directly observed unique surface spectator or intermediate species as well as potentially slower conversions in mixtures of the two components. The generation of toxic species in ENDS liquids at low temperatures highlights the dangers of low-temperature ENDS use.

Abstract
Waterpipe smoking is a form of tobacco use that causes nicotine/tobacco dependence and has become a global health problem. In the current study, the association of rs16969968 SNP in the CHRNA5 gene with waterpipe dependence was investigated. A total of 386 men and women who used a waterpipe to smoke tobacco were recruited and divided into less dependent and more dependent smokers based on their score on the Lebanon Waterpipe Dependence Scale (LWDS). Results showed a significant difference in the distribution of GG, GA, and AA genotypes by waterpipe dependence status (P<0.001). The more dependent group showed a higher frequency of the AA genotype than the less dependent smokers' group (38% versus 23% respectively). In addition, the more dependent smokers exhibited more A allele than less dependent smokers (53% versus 37% respectively, P<0.001). In conclusion, there is an association between the rs16969968 SNP and waterpipe dependence as assessed by the LWDS.

Abstract
INTRODUCTION The capability of a commercial waterpipe electric heater to simulate the waterpipe charcoal heating system using waterpipe tobacco consumption as a metric was evaluated, and a research-grade waterpipe electric heater to standardize waterpipe tobacco emission testing was designed. METHODS The experiment was conducted in two phases. In Phase 1, tobacco was heated using either charcoal or a commercial electric heater. The tobacco temperature was recorded during a 57-minute machine-smoking session and tobacco consumption was measured. In Phase 2, a similar procedure was followed using a novel research-grade electric heater. RESULTS In Phase 1, tobacco consumption using either charcoal or the commercial electric heater averaged 31.35% and 20.56%, respectively. In Phase 2, tobacco consumption using the research-grade electric heater, set at target temperatures of 470, 430, 400, 380, 370 and 350°C, averaged 55.74, 41.22, 40.18, 39.10, 31.57 and 26.14%, respectively. CONCLUSIONS The commercial electric heater did not reach consumption levels seen in the charcoal heating system, whereas the research-grade electric heater did and can be used as part of a standardize waterpipe tobacco emission testing regimen.

Abstract
INTRODUCTION Despite its known adverse effects on human health, waterpipe smoking is increasing in popularity worldwide. However, compared to cigarettes, regulation of waterpipe product smoking lags behind and presents unique challenges. In search for regulatory options, this systematic review analyzes 36 studies on the differential effects on human health of the waterpipe characteristics including smoking products, heating sources, device components, and packages. METHODS A systematic review was performed according to PRISMA guidelines, revealing 443 unique citations. After screening, 36 studies were included in the results. Research articles were selected to inform on differential effects caused by product characteristics on adverse health effects, attractiveness, addictiveness and prevalence of waterpipe use. RESULTS Flavors are the key aspect that defines attractiveness of waterpipe product smoking. All waterpipe products, with or without nicotine, produce toxicants in similar quantities as cigarettes. Heating sources for waterpipe tobacco include charcoals and electrical heating. Both heating sources increase toxicant emissions in different ways. Hoses and mouth tips are device components that are often shared in waterpipe smoking. Sharing influences attractiveness by enriching the social experience. At the same time, it influences the transfer of infectious diseases by bacteria and viruses from one smoker to another. Studies showed that more generic and less attractive packages with health warnings are effective in reducing the attractiveness of waterpipe smoking. CONCLUSIONS Based on our findings, we advise to include all waterpipe products, tobacco and non-tobacco, with or without nicotine, in tobacco product regulations and smoking bans in order to: ban waterpipe molasses with characterizing flavors or ban the use of flavorings at any level; mandate dissemination of information on all waterpipe tobacco elements to the national regulator; prescribe testing to regulate contents of waterpipe smoking products and heating sources. Moreover, we advise to stimulate research on emissions of waterpipes.

Abstract
Background. Waterpipe tobacco smoking is associated with many negative health outcomes due to toxicants produced by heating the tobacco using charcoal or electrical heaters. Little is known about how young adult waterpipe tobacco smokers perceive harms of these heating sources. Aims. To examine young adult waterpipe tobacco smokers' perceived harms of electrical heaters and charcoal to heat waterpipe tobacco. Method. This online cross-sectional study enrolled 18- to 32-year-olds who smoked waterpipe tobacco within the past 30 days. Participants completed measures assessing, for each heating source, amount and knowledge of toxicants released (e.g., carbon monoxide, cancer-causing chemicals), perceived safety, worry about inhaling toxicants, perceived health risk, desire to quit, and intention to smoke in the next month. Question order for knowledge of and perceived harms was counterbalanced for each heating source. Results. Analyses were based on responses from 199 participants. Perceived harms for both heating sources were average to low. Despite some question order effects, participants viewed charcoal as more harmful than electrical heaters. Participants knew more about chemicals released from charcoal than electrical heaters. Greater knowledge of chemicals released by both heating sources correlated positively with perceived harms. Perceived harms were associated with a stronger desire to quit, yet unrelated with likelihood of smoking waterpipe during the next month. Discussion. Many young adult waterpipe tobacco smokers view charcoal as more harmful than electrical heaters, although knowledge about harms for each heating source is poor. Conclusion. Interventions are needed to inform the public about harms of waterpipe heating sources in order to curb use.
