Help-seeking behaviours among cannabis consumers in Canada and the United States: Findings from the international cannabis policy study.

Background: Little literature exists on what sources of help individuals utilize for cannabis-related problems. The current study examined the percentage of consumers who sought help to manage cannabis-related problems, such as perceived cannabis use disorder, the most common sources of help sought, and factors associated with help-seeking.

Methods: Past 12-month cannabis consumers ( = 13,209) completed an online survey from the International Cannabis Policy Study.

Association of fully branded, standardized packaging and limited flavor and brand descriptors of e-liquids with interest in trying products among youths in Great Britain.

Background And Aims: Many vaping products feature bright colors and novel brand names and flavor descriptors, which may appeal to youth. We measured the strength of the associations between e-liquid packaging design (branded, white standardized or white standardized limiting brand and flavor descriptors) and perceived peer interest in trying the e-liquids among youth.

Design: A between-subjects online experiment.

Changes in Cannabis Use Patterns in Psychiatric Populations Pre- and Post-Legalization of Recreational Cannabis Use in Canada: A Repeated Cross-Sectional Survey.

Objective: Since the federal Canadian government legalized cannabis in 2018, cannabis use in the general population has slightly increased. However, little is known about the impact of cannabis legalization on pattens of cannabis use in psychiatric populations.

Method: We studied changes in daily/almost daily and average 30-day cannabis use amongst individuals currently using cannabis who reported past 12-month experiences of specific mental health disorders and among those without past 12-month experiences of any mental health disorder before and after Canadian legalization of recreational cannabis use ( = 13,527).

Differences in smoking cessation behaviors and vaping status among adult daily smokers with and without depression, anxiety, and alcohol use: Findings from the 2018 and 2020 International Tobacco Control Four Country Smoking and Vaping (ITC 4CV) Surveys.

This study examined differences in quit attempts, 1-month quit success, and vaping status at follow-up among a cohort of 3709 daily smokers with and without depression, anxiety, and regular alcohol use who participated in both the 2018 and 2020 International Tobacco Control Four Country Smoking and Vaping (ITC 4CV) Surveys. At baseline, a survey with validated screening tools was used to classify respondents as having no, or one or more of the following: 1) depression, 2) anxiety, and 3) regular alcohol use. Multivariable adjusted regression analyses were used to examine whether baseline (2018) self-report conditions were associated with quit attempts; quit success; and vaping status by follow-up (2020).
