Age differences in cannabis-related perceptions, knowledge, and sources of information among adults in the post-legalization era in Quebec, Canada.

Individuals access and perceive information about cannabis differently according to age groups. This study compared differences in beliefs and knowledge regarding cannabis, and exposure to information, advertisement, and prevention messages among emerging (18-24 years old), prime-age (25-44), middle-age (45-64), and old-age adults (65 and over). Participants (n=2,001) completed online questionnaires regarding their sociodemographic characteristics, mental health perception, cannabis use, sources of cannabis information, and exposure to advertisement and prevention messages.

Factors related to the low-risk perception of driving after cannabis use.

Introduction: Modifying risk perceptions related to driving after cannabis use (DACU) could deter individuals from enacting this behavior, as low-risk perception is associated with DACU engagement. This study identified sociodemographic characteristics, substance use, other driving behaviors, peer norms, and psychological characteristics that are associated with lower risk perception regarding DACU.

Methods: Canadian drivers aged 17-35 who have used cannabis in the past year (n = 1,467) completed an online questionnaire.

Typologies of Canadian young adults who drive after cannabis use: A two-step cluster analysis.

Young adults that drive after cannabis use (DACU) may not share all the same characteristics. This study aimed to identify typologies of Canadians who engage in DACU. About 910 cannabis users with a driver's license (17-35 years old) who have engaged in DACU completed an online questionnaire.
