Older Canadians' Perceptions of the Safety, Effectiveness and Accessibility of Cannabis for Medicinal Purposes: A Cross-Sectional Analysis.

ABSTRACT

BACKGROUND AND OBJECTIVE: Cannabis use is increasing among older adults, with use primarily for medicinal purposes. Much of the evidence on perceptions of cannabis is derived from younger populations and current users of cannabis. The purpose of this study was to describe community-dwelling older Canadians' perceptions of cannabis effectiveness, safety and accessibility for medicinal purposes and to identify factors influencing cannabis perceptions. METHODS: An online survey of older adults' perceptions, knowledge and experiences with cannabis was completed between February and September 2022. The survey was open to English-speaking and French-speaking Canadians aged 50 years and older regardless of their cannabis use history. RESULTS: A total of 1615 Canadians completed the survey. Respondents identified primarily as men (49.7%) or women (48.5%) of Caucasian decent. The majority of participants viewed cannabis as a reasonable alternative (65.8%) and an effective (70.5%) treatment modality for symptom management in older adults. Few respondents (16.4%) felt that older adults compared to younger adults were at a higher risk of side effects and 34.5% felt that cannabis is safe to use with most medicines. Cannabis perceptions were influenced by gender, cannabis use history (prior use vs current use) and reasons for cannabis use (recreational purposes vs medicinal purposes vs both purposes). CONCLUSIONS: Older Canadians have a positive view of the role of cannabis in symptom management. The perceptions of cannabis safety and effectiveness were influenced by gender, cannabis use history and reasons for cannabis use. Healthcare professionals should leverage these perceptions when discussing cannabis with their older patient populations.
