Hookah use among college students: Prevalence, mental health and drug use

s / Drug and Alcohol Dependence 146 (2015) e118–e201 e131 be presented from a population-based survey in California on the relationship of health status with attitudes toward and use of MM. Methods: The California Quality of Life Survey (2012–13) is a telephone follow-back survey of a subset of individuals (n=2267) who had participated in a statewide probability survey. The followback survey obtained information on health conditions, attitudes, and behaviors. Analyses examined socio-demographic characteristics and health conditions associated with attitudes toward and use of MM in the past year. All estimates were weighted to account for survey design. Results:Overall, 27.4%of the sampledisapprovedofMMuseand was higher among females; Asians and Hispanics; and individuals thatweremarried/cohabitating, had lower education andSES,were foreign-born,heterosexual (vs. sexualminority), in fair/poorhealth, andhadno illicit druguse in past year (all p<0.05). Less disapproval ofMMusewas associatedwith having diabetes, chronic back problems, major depression, and alcohol or drug abuse/dependence (all p<0.05). An estimated 5.2% reported that they had obtainedMM in thepast year. Past-yearuseofMMwasassociatedwithyounger age, unmarried status, less than college degree, U.S. birth, and illicit use of drugs (all p<0.05). Although therewas nodifference in their selfreported overall health status, MM users had higher rates of drug abuse/dependence, alcohol dependence,major depression, chronic pain, HIV/AIDS, and gynecological problems (all p<0.05). Conclusions: Disapproval of MM was associated with poorer overall health status, but was less among individuals that had several health conditions commonly associated with MM use. Study findings may be used to inform policies related to MM use and interventions to reduce behavioral health problems among users.

Yet, it seems that hookah users may underestimate the deleterious effects of hookah use, potentially due to the lack of regulation of this substance in theUS. This studyexamines theprevalence, demographic characteristics, relation to other alcohol and substance use, and themental health and stress levels associatedwith hookah use among undergraduates at a small, Northeastern university. Methods: Data were drawn from the American Health Association-National College Health Assessment (Spring 2009; N=1799) at one large, northeastern university. Relationships between hookah use and other drug use, mental health problems, and stress levels were examined using logistic regression analyses. Results: 14.1% (253/1799) of undergraduates in this sample usedhookah in thepastmonth.Hookahusersweremore likely tobe male, older, and participants of Greek life than non-hookah users. Hookah users were more likely to use other substances, including cigarettes, cannabis, alcohol, cocaine, and amphetamines, compared with those who had not used hookah. Of all the substances measured, alcohol and cigarette use weremost strongly associated with hookah use. Hookah use was not significantly associated with increased mental health problem or higher stress levels. Conclusions: Hookah users are significantly more likely to use other substances, including alcohol, cigarettes, cannabis, cocaine, and amphetamines, compared with those who have not used hookah. This is similar to cigarette smoking, yet, unlike cigarette smoking, hookah use shows no link with mental health problems or stress. Policymakers should consider regulating hookah products and hookah lounges to demystify the perception that hookah smoking is safer and less addictive than cigarette smoking.

Lukas2,3 1 Imaging Center, McLean Hospital, Belmont, MA, United States 2 Department of Psychiatry, Harvard Medical School, Boston, MA, United States 3 Behavioral Psychopharmacology Research Lab, McLean Hospital, Belmont, MA, United States Aims:As legalizationofmedical and recreationalmarijuana (MJ) continues to spread, topping headlines and ballots across the country, conversations about MJ often highlight potential benefits. Not surprisingly, national trends show the perception of risk and harm related toMJ is at an all-time low. This viewpersists despite investigationswhich highlight significant cognitive and neural alterations inMJ smokers. Given the rise inMJ use, specifically among youth, it is critical todetermine if patternsofMJuse canpredict impairments in cognitive functioning and white matter alterations. Methods: Regression analyses of 44 chronic, heavy MJ smokers revealed that more smoking episodes and higher grams of MJ used per week predicted worse performance on cognitive tasks, particularly those of executive function, including the Stroop ColorWord Task and the Wisconsin Card Sorting Test (WCST). Results: Specifically, more smoking episodes and grams used per week predicted increased commission errors and lower percent accuracy on the Stroop, aswell as increased losses of set on the WCST. Higher urinary cannabinoid level predicted fewerWCST categories and increased perseverative errors. Patterns of MJ use also predicted whitematter alterations, with higher amounts andmore frequent use of MJ predicting increased fractional anisotropy (FA), a measure of white matter coherence. Interestingly, once divided into early (MJ use prior to age 16) and late (MJ use after age 16) onset groups, results indicated the relationship between FA andMJ use was entirely attributed to the early onset group, suggesting a differential impact of MJ based on initiation of use. Conclusions: Findings suggest that early exposure to MJ may result in a potential failure to prune unnecessary connections during neuromaturation. These data have implications for more efficient treatment options, as strategies may be individualized based on age of onset and current patterns of MJ use.
