Assessing hookah use in one of the venues of its use (hookah bars) will aid the understanding of the toxins and exposure for the user. In Florida, smoking is prohibited in public places under the Florida Clean Indoor Act but permitted in establishments that have less than 10% gross revenue from food. PURPOSE: To assess the CO level of hookah cafe patrons, using traditional bar patrons as a comparison. METHODS: After IRB approval, a nighttime field study of patrons (aged >18 years) exiting hookah cafes and traditional bars in 2009 was conducted, using sidewalk locations immediately outside these establishments in a campus community. As hookah cafes and bars are typically entered and exited in groups, every other group of people exiting the establishment was approached. For comparison purposes, the sample collected was similar in number, 173 hookah cafe and 198 traditional bar participants. RESULTS: Results from analysis conducted in 2010 indicate that patrons of hookah cafes had significantly higher CO levels (mean=30.8 parts per million [ppm]) compared to patrons of traditional bars (mean=8.9 ppm). Respondents who indicate no cigarette use in the past month but had visited a hookah cafe still demonstrated significantly higher CO values (mean=28.5 ppm) compared to those exiting traditional bars (mean=8.0 ppm). Current cigarette smokers also produced significantly more CO if exiting a hookah cafe (mean=34.7 ppm) compared to a traditional bar (mean=13.3 ppm). CONCLUSIONS: CO levels are higher for patrons of hookah cafes, for both current and non-cigarette smokers. Although users report that they perceive hookah to be less harmful than cigarettes, the greater CO exposure for hookah users that was observed in this study is not consistent with that perception.

Alternative tobacco products, including hookah, pose a public health threat to tobacco prevention efforts, especially among adolescents. METHODS: Florida Youth Tobacco Survey data, representing all public high school students in the state, were analyzed to assess the prevalence of lifetime and current hookah use and were compared by demographic groups. Multiple years of data (2007-2012) were examined to assess changes over time. RESULTS: During the past 6 years, there was an increase in lifetime hookah use among Florida high school students. While males remained at a higher rate overall, female adolescents increased at a faster rate. Hispanic and non-Hispanic White respondents reported increased trends as well. Current use trends did not change over 4 years, remaining at about 8%. CONCLUSIONS: Hookah is a new tobacco product in the United States that appears attractive to youth, with dramatic increases among the state population. While cigarette use among youth is declining in Florida, the increasing uptake of alternative tobacco products may lessen the overall public health gains for tobacco use. There is a need for continued monitoring of hookah use among the adolescent population, for both prevention and cessation efforts as well as policy interventions to address this emerging trend.

The trends are critical as policy to prevent uptake among adolescents is considered. The purpose of this study is to describe the prevalence of e-cigarette use and potential correlates for use. Associations between e-cigarettes, cigarettes, and hookah are assessed. METHODS: This study used data from the 2013 Florida Youth Tobacco Survey. Prevalence estimates were calculated in 2014 and differences were determined based on CIs. Adjusted logistic regression models were used to identify correlates of e-cigarette use among participants based on demographic and other tobacco products used. RESULTS: There were no sex differences in middle school, whereas male high school students reported higher use than their female counterparts. Cigarette smoking and hookah use were significantly associated with ever and current e-cigarette use among both middle and high school students. CONCLUSIONS: Although e-cigarettes are being assessed as a potential replacement product for traditional tobacco, evidence from this study indicates the possibility of multiple product use among adolescents. E-cigarettes are not only associated with traditional cigarettes, but also with hookahs, a similar emerging product that offer tobacco flavors that may appeal to adolescents. Notably, many e-cigarette users also reported no cigarette or hookah use. Descriptors Links Book Title Database Publisher American Journal of Preventive Medicine.

The purpose of this study was to assess hookah use and identify associations with cigarette smoking and demographic factors. METHODS: An intercept sampling method was used at various locations on a large university campus in the southeastern United States, yielding a high participation rate (52%). A total of 1,203 participants completed a computer-aided survey that assessed the use of tobacco products. The sample characteristics were then weighted to match the University population of students enrolled during the same semester. Bivariate (chi-square and t-test) and multivariate (logistic regression) tests of association were conducted to assess differences between cigarette and hookah users. RESULTS: Hookah smoking exceeded cigarette smoking for both ever use (46.4% vs 42.1%) and past year use (28.4% vs 19.6%). Females and males used hookah at similar rates. Hispanic respondents had the highest prevalence of current use of hookah (18.9%) and cigarettes (16.4%). CONCLUSIONS: As hookah surpasses cigarette use, efforts need to be made to slow the increase in new tobacco products that are attractive to young adults and that pose many of the same health risks as those related to traditional tobacco products. Prevalence of all emerging tobacco products, including hookah, and the relationship with cigarette use needs to be monitored on an ongoing basis.

Unfortunately, clinical guidelines have focused on traditional cigarettes with limited attention regarding these emerging public health issues. Thus, it is critical to understand how healthcare professionals view this issue and are responding to it. This qualitative study explored knowledge, beliefs and clinic-based practices regarding traditional and alternative tobacco products (cigar-like products, smokeless tobacco, hookah, e-cigarettes) and marijuana among rural and urban Georgia primary healthcare providers. The sample comprised 20 healthcare providers in primary care settings located in the Atlanta Metropolitan area and rural southern Georgia who participated in semi-structured interviews. Results indicated a lack of knowledge about these products, with some believing that some products were less harmful than traditional cigarettes or that they may be effective in promoting cessation or harm reduction. Few reported explicitly assessing use of these various products in clinic. In addition, healthcare providers reported a need for empirical evidence to inform their clinical practice. Healthcare providers must systematically assess use of the range of tobacco products and marijuana. Evidence-based recommendations or information sources are needed to inform clinical practice and help providers navigate conversations with patients using or inquiring about these products.

METHODS: We conducted a cross-sectional survey assessing sociodemographics, tobacco use, interest in ENDS and smokeless tobacco among smokers, and knowledge about ENDS among 2,501 US adults recruited through an online consumer panel. We oversampled tobacco users (36.7% current cigarette smokers), ethnic minorities, and southeastern US state residents. RESULTS: On average, participants were more interested in ENDS than smokeless tobacco across all reasons provided. Additionally, they were less interested in either product because of their potential use in places prohibiting smoking or due to curiosity and more interested in reducing health risk or cigarette consumption or to aid in cessation. We documented high rates (27.9%) of misbeliefs about Food and Drug Administration approval of ENDS for cessation, particularly among current smokers (38.5%). Also, 27.2% of current smokers had talked with a health care provider about ENDS, with 18.0% reporting that their provider endorsed ENDS use for cessation. Furthermore, cluster analyses revealed 3 groups distinct in their interest in the products, sociodemographics, and smoking-related characteristics. CONCLUSIONS: This study highlights higher interest in ENDS versus smokeless tobacco and greater interest in both for harm reduction and cessation than due to novelty or smoking restrictions. Developing educational campaigns and informing practitioners about caveats around ENDS as cessation or harm reduction aids are critical. Descriptors Links Book Title Database Publisher .

We examined use patterns of various tobacco products, marijuana, and alcohol using data from the baseline survey of a multiwave longitudinal study of 3418 students aged 18-25 recruited from seven U.S. college campuses. We assessed sociodemographics, individual-level factors (depression; perceptions of harm and addictiveness,), and sociocontextual factors (parental/friend use). We conducted a latent class analysis and multivariable logistic regression to examine correlates of class membership (Abstainers were referent group). Results indicated five classes: Abstainers (26.1% per past 4-month use), Alcohol only users (38.9%), Heavy polytobacco users (7.3%), Light polytobacco users (17.3%), and little cigar and cigarillo (LCC)/hookah/marijuana co-users (10.4%). The most stable was LCC/hookah/marijuana co-users (77.3% classified as such in past 30-day and 4-month timeframes), followed by Heavy polytobacco users (53.2% classified consistently). Relative to Abstainers, Heavy polytobacco users were less likely to be Black and have no friends using alcohol and perceived harm of tobacco and marijuana use lower. Light polytobacco users were older, more likely to have parents using tobacco, and less likely to have friends using tobacco. LCC/hookah/marijuana co-users were older and more likely to have parents using tobacco. Alcohol only users perceived tobacco and marijuana use to be less socially acceptable, were more likely to have parents using alcohol and friends using marijuana, but less likely to have friends using tobacco. These findings may inform substance use prevention and recovery programs by better characterizing polysubstance use patterns.
