Sexual minority (SM) young adults have higher rates of substance use than heterosexuals, but little is known about daily use of multiple substances, which confer numerous health risk for this population. Using daily diary data from a smartphone-based study, we examined the associations between sexual identity (i.e., SM vs. heterosexual) and patterns of same-day multiple substance use (i.e., cigarettes and alcohol, cigarettes and cannabis, alcohol and cannabis, and all three substances). Young adult smokers (N=147, aged 18–26, 51.7% female, 41.5% SM, 40.8% White) reported consecutive daily assessments on substance use during 30 days. We used generalized estimating equations to examine associations between sexual identity and patterns of same-day multiple substance use, controlling for demographic factors and psychological distress. Of 2,891 daily assessments, 16.7% reported same-day use of cigarettes and alcohol, 18.1% cigarettes and cannabis, 1.5% alcohol and cannabis, and 15.0% use of all three substances. SM participants (vs. heterosexuals) had significantly greater odds of reporting days with use of cigarettes and cannabis [Adjusted Odds Ratio (AOR) = 2.05, 95% Confidence Interval (CI) = 1.04–4.01] and use of all three substances (AOR = 2.79, 95% CI = 1.51–5.14) than days with single substance use or no use. These findings warrant tailored interventions addressing multiple substance use among SM young adults and temporally accurate measures of multiple substance use patterns.

Introduction: Many cannabis dispensaries market and sell their products online through websites designed to attract and maintain customers; often, these websites incorporate a variety of product claims and other marketing tactics. This study evaluated website content, product pricing and discounts on dispensary websites in California and Nevada, states that legalized recreational cannabis in 2016. Methods: We content coded product availability, marketing claims and discounts on cannabis dispensary websites in the San Francisco Bay Area (N = 34) and Reno (N = 15) from March to June 2020 using a web crawler to scrape pricing information for four product types. We conducted bivariate analyses comparing both locations. Results: Prices were significantly lower for flower, edibles, and concentrates in Reno compared to the Bay Area, but not cartridges. In both areas, a range of marketing claims were made regarding the health effects of certain products. The most common were that cannabis products treated pain, nausea/vomiting, spasms, anxiety, insomnia, and depression. Products were also said to promote creativity and euphoria. Other marketing claims related to potency, pleasure enhancement, and improved social interactions. Discounts targeted to senior citizens and veterans were found on over half of all websites. Conclusions: Dispensary websites in the Bay Area and Reno frequently make health-related claims which should not be allowed in absence of scientific evidence. Non-health related claims are similar to those used for selling e-cigarettes and other tobacco products. Monitoring cannabis dispensary websites provides insight into local sales tactics and may help identify subpopulations for research on behavioral impacts of cannabis marketing activities.

In order to understand the impact of individual communities on global sustainability, we need a community sustainability assessment system (CSAS). While many sustainability assessment systems exist, they prove inadequate to the task. This article presents the results of a systematic review of the literature on existing sustainability assessment systems; offers a definition of a sustainable community; provides a multi-scale, systems approach to thinking about community; and makes recommendations from the field of performance measurement for the construction of a CSAS.
