    30. 30. Waterpipe use has been reported in 33 states. <br />200-300 waterpipe cafes have opened in the U.S. since 1999 (Smokeshop Magazine, 2004) “often near college campuses”. <br />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.<br />Is the U.S. in an early stage of a waterpipe epidemic among college students?<br />

    37. 37. Waterpipeuse more common on weekend.<br />Majority purchased their waterpipe on the internet.<br />Majority use flavored tobacco, fruit flavor most popular.<br />Majority smoke intermittently.<br />Majority are confident they could quit, most of whom have no intention of quitting.<br />Majority believe that cigarettes are more harmful and addictive.<br />Use patterns among US college youths<br />Smith-Simone, Maziak, Ward, and Eissenberg. 2008<br />

    39. 39. Social dimension of waterpipeuse<br />Asfar T, Maziak W, et al. BMC Public Health 2005.<br />
    40. 40. <ul><li>Maassel’s aromatic mild smoke, wide variety and availability, simplification of the waterpipe preparation process were perhaps critical for the renewed appeal of the waterpipe
    41. 41. The internet & other transnational media (e.g. satellite TV) lead to commercializing & glamorizing waterpipe, particularly among youths.
    42. 42. The reduced-harm perception, based on the water filtering myth.
    43. 43. The thriving café culture.
    44. 44. All these factors have perhaps created conditions for a perfect storm that sparked the global waterpipe epidemic.</li></ul>Factors behind the current waterpipe pandemic<br />
    45. 45. What about waterpipe tobacco/nicotine dependence?<br /><ul><li>Particularly popular among young adults and teens in SW Asia:
    46. 46. Syria, 45% of college students at Aleppo University report ever use (29.8% women; Maziak et al., 2004)
    47. 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. 48. Lebanon, 23-30% of Beirut university students report current use (Tamim et al, 2003; Chaaya et al., 2004).
    49. 49. Lebanon, 25.6% of 11-17 year olds in Beirut reported past 30-day use (Tamim et al., 2007).
    50. 50. Global spread suggested by published data from: Brazil, Canada, Germany, Korea, Ukraine, U.S.</li></li></ul><li>Waterpipe users are exposed to nicotine (N = 37).<br />Data from Blank et al., Drug Alcohol Dep, 2011.<br />

    53. 53. Thread title: “Why is hookah not addictive?”<br />“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)<br />“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)<br />“. . . 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) <br />Anecdotal evidence for waterpipe dependence.<br />
    54. 54. Empirical evidence: drug-seeking and diff. quitting?<br /><ul><li>Random sample of 268 Syrian waterpipe smokers.
    55. 55. 43% reported more frequent use than when they started
    56. 56. 55% reported being “somehow” or “very” hooked on waterpipe (83% of daily smokers).
    57. 57. 63% choose café/restaurant based on waterpipe availability (77% of daily smokers)
    58. 58. 42% carry waterpipe with them (69% of daily smokers).
    59. 59. 59% made an unsuccessful quit attempt in the past year (78% of daily smokers). </li></ul>From Maziak et al., 2004.<br />

    61. 61. Among Arab-American adolescents, odds of experimenting with cigarettes were 8 times greater among ever waterpipe smokers (Rice et al., 2006).<br />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).<br />Youth studies in the EMR show that first experimentation with tobacco through a waterpipe precedes that with cigarettes.<br /> Is waterpipe use a “gateway” to cigarettes?<br />

    69. 69. Addition of waterpipe in assessments of tobacco use may help counteract the perception that it is benign to use.<br />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).<br />More must be done to limit minors’ access to waterpipe products.<br />Enforce clear warning labels on waterpipe tobacco, and ensure that common but misleading descriptors such as “0% tar” are removed from packaging.<br />Enforce advertisement bans to include waterpipe.<br />Waterpipe Policy<br />
