30. Waterpipe use has been reported in 33 states. 200-300 waterpipe cafes have opened in the U.S. since 1999 (Smokeshop Magazine, 2004) “often near college campuses”. Waterpipe cafes now exist near many large universities including Virginia Commonwealth (Richmond), Arizona State (Tempe); Colorado State (Fort Collins); Iowa (Iowa City); Nebraska (Lincoln); Kent State (Kent, OH), Weber State (Ogden, UT), University of Memphis. Is the U.S. in an early stage of a waterpipe epidemic among college students?

37. Waterpipeuse more common on weekend. Majority purchased their waterpipe on the internet. Majority use flavored tobacco, fruit flavor most popular. Majority smoke intermittently. Majority are confident they could quit, most of whom have no intention of quitting. Majority believe that cigarettes are more harmful and addictive. Use patterns among US college youths Smith-Simone, Maziak, Ward, and Eissenberg. 2008
38. I enjoy the taste It’s a good way to socialize with friends It helps me to feel relaxed I enjoy the smell It helps me to feel less stressed It’s something to do when I feel bored Waterpipesmoke is less harsh than cigarette smoke I like trying things that are new, different, or “hip” It helps me not smoke cigarettes It helps me not use other tobacco products besides cigarettes (e.g., cigars or chew) Why youths smoke waterpipe Smith-Simone, Maziak, et al, 2008. Maziak et. at, 2004.
39. Social dimension of waterpipeuse Asfar T, Maziak W, et al. BMC Public Health 2005.

41. The internet & other transnational media (e.g. satellite TV) lead to commercializing & glamorizing waterpipe, particularly among youths.
44. All these factors have perhaps created conditions for a perfect storm that sparked the global waterpipe epidemic.Factors behind the current waterpipe pandemic

46. Syria, 45% of college students at Aleppo University report ever use (29.8% women; Maziak et al., 2004)
47. Jordan, 61% of university students reported ever use; 43% reported past 30-day use (random sample of 548 students across four universities; Azab et al., 2010).
48. Lebanon, 23-30% of Beirut university students report current use (Tamim et al, 2003; Chaaya et al., 2004).
49. Lebanon, 25.6% of 11-17 year olds in Beirut reported past 30-day use (Tamim et al., 2007).

53. Thread title: “Why is hookah not addictive?” “It is addictive. Period. End of story. Maybe not as easily habit forming as cigarettes because hookah is not a convenient as a pack of smokes. But rest assured, it is addictive. . .” (Lukasa) “I'd say I'm pretty hooked. I smoke anywhere from 1-3 times per day, virtually every day of the week. It's pretty rare that I'll miss a day. . .” (Yashman19) “. . . Lets not kid ourselves, when I smoked hookah lots I started to get hooked and craved tobacco, then I realized this and quit for a while and don't smoke as much anymore. The nicotine in the tobacco for hookahs and the nicotine in cigarettes is identical, so it is equally addictive.” (Joseph) Anecdotal evidence for waterpipe dependence.
59. 59% made an unsuccessful quit attempt in the past year (78% of daily smokers). From Maziak et al., 2004.
60. 100 Urge Restlessness 40 Craving 30 Score 20 10 0 Pre Post Time (relative to waterpipe smoking) Maziak et al., 2006 (61 Syrian waterpipe smokers, overnight abstinence; CO increased 31.5 ppm) Empirical evidence: abstinence-induced withdrawal?
61. Among Arab-American adolescents, odds of experimenting with cigarettes were 8 times greater among ever waterpipe smokers (Rice et al., 2006). In a population-based study of young military recruits (US), waterpipe users were more likely than non-users to plan to initiate cigarette smoking in the next year (Ward et al., 2006). Youth studies in the EMR show that first experimentation with tobacco through a waterpipe precedes that with cigarettes. Is waterpipe use a “gateway” to cigarettes?

68. Tobacco control Policy Framework Convention on Tobacco Control (FCTC) Not clear what the effect of FCTC policies will be on cigarette and in particular waterpipe use in the EMR Waterpipe use generally ignored or given little attention despite it being as important as cigarettes in EMR cigarette Cigarette
69. Addition of waterpipe in assessments of tobacco use may help counteract the perception that it is benign to use. Smokefree air laws seem to have had the opposite effect on hookah establishments, bolstering them as they are often unaddressed or exempted from many laws (ALA, 2007). More must be done to limit minors’ access to waterpipe products. Enforce clear warning labels on waterpipe tobacco, and ensure that common but misleading descriptors such as “0% tar” are removed from packaging. Enforce advertisement bans to include waterpipe. Waterpipe Policy
70. Smoker toxicant exposure: co, nicotine, carcinogens. Large-scale surveys in the U.S. and elsewhere to understand current prevalence and identify targets populations and key messages for prevention and treatment efforts. Epidemiological work to understand disease risk. Develop and test policy initiatives to curb the spread of waterpipe. . . . But we have the science to catch up quickly! We are well behind the curve. . .
