BackgroundK2 or "spice" has emerged as a popular legal alternative to marijuana among adolescents and young adults. However, no data has been published assessing prevalence of and associations with ever K2 use in any population. This study's aims were to examine prevalence of ever K2 use among a sample of college students, to determine characteristics of persons who use K2, and to access the association between K2 and other drug use.FindingsEver use of K2 was reported by 69 (8%) of the sample of 852 college students. Response rate was 36%. Bivariate and multivariate analyses assessed whether sociodemographic characteristics and other drug use were associated with ever use of K2. Ever use of K2 was reported by 69 (8%) of the sample. Among these 69 individuals, 61 (88%) had used a cigarette and 25 (36%) had used a hookah to smoke K2. In multivariate analyses, K2 use was more common in males (vs. females, adjusted Odds Ratio (aOR) = 2.0, 95% Confidence Interval (CI) = 1.2-3.5, p = 0.01) and 1st or 2nd year college students (vs. 3rd year or above, aOR = 2.4, 95% CI = 1.2-5.0, p = 0.02).ConclusionsEver use of K2 in this sample was higher than ever use of many other drugs of abuse that are commonly monitored in adolescents and young adults. Although DEA had banned five synthetic cannabinoids recently, clinicians and public health officials concerned with substance abuse in youth should be aware of and monitor the use of this drug in college students over time.

Legalization of cannabis in Colorado was associated with short-term reductions in opioid-related deaths. As additional data become available, research should replicate these analyses in other states with legal recreational cannabis.

BackgroundThe emergence of hookah is being noted on college campuses and in large U.S. cities and evidence points to an increasing trend for college students. The purpose of this study was to assess hookah use and identify associations with cigarette smoking and demographic factors.MethodsAn 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.ResultsHookah 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%).ConclusionsAs 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.

We examined the cost-effectiveness of a care coordination/home telehealth (CCHT) programme for veterans with diabetes. We conducted a retrospective, pre-post study which compared data for a cohort of veterans (n=370) before and after the introduction of the CCHT programme for two periods of 12 months. To assess the cost-effectiveness, we converted the patients' health-related quality of life data into Quality Adjusted Life Year (QALY) utility scores and used costs to construct incremental cost-effectiveness ratios (ICERs). The overall mean ICER for the programme at one-year was $60,941, a value within the commonly-cited range of cost-effectiveness of $50,000-100,000. The programme was cost-effective for one-third of the participants. Characteristics that contributed to cost-effectiveness were marital status, location and clinically relevant co-morbidities. By targeting the intervention differently in future work, it may become cost-effective for a greater proportion of patients.

Water pipe use appears to be widespread among middle and high school students. Further research is needed to assess the health risks associated with water pipe tobacco smoking as well as young people's attitudes toward this form of tobacco use.
