Reasons for Use and Perceived Effects of Medical Cannabis: A Cross-Sectional Statewide Survey

Abstract

Introduction: Medical cannabis (MC) is available upon certification for one of several qualifying conditions in Florida, USA. Previous studies suggested that some people seek cannabis for medical conditions/symptoms beyond those legally permitted. Yet, data remains limited on patient motives for seeking MC and their experiences around its impact on their health. We aimed to compare reported qualifying conditions for MC certification with the most frequently self-reported reasons for using MC while assessing the alignment between the two and understand the perceived impacts of MC on self-reported conditions and symptoms. Methods: We conducted a cross-sectional study using survey data from the Medical Marijuana & Me (M3) Databank of individuals receiving MC in Florida, USA, in 2022. Participants were recruited via convenience sampling from nine MC clinics/clinic networks across Florida and were asked to fill out an online survey. The study measures included sociodemographic variables, self-reported health conditions, self-reported main reasons for using MC, self-reported qualifying conditions for MC certification, and self-reported perceived impact of MC on health conditions. We cross-tabulated reported qualifying conditions and reasons for MC use and reported the perceived impact per condition. Results: A total of 632 participants completed the survey, of whom 396 (62.66%) were female, and 471 (74.53%) were non-Hispanic White. The median (IQR) age was 45 (35, 58). The most frequently reported qualifying conditions were post-traumatic stress disorder (PTSD) (n=187, 29.59%), a condition not on the qualifying conditions list (n=175, 27.69%), medical conditions of the same kind/comparable to those listed (n=140, 22.15%), and chronic nonmalignant pain (n=62, 25.63%). The top ten most frequently reported reasons for using MC were anxiety (n=383, 60.60%), chronic pain (n=278, 43.99%), depression (n=252, 39.87%), PTSD (n=220, 34.81%), headaches/migraine (n=134, 21.20%), fibromyalgia (n=67, 10.60%), attention-deficit/hyperactivity disorder (ADHD) (n=59, 9.34%), bipolar disorder (n=53, 8.39%), high blood pressure (n=41, 6.49%), and cancer, (n=18,2.85%). Of respondents, 70-90% with each qualifying condition reported it as one of the main reasons for using MC. Most respondents reported improvement of anxiety (n=430/451, 95.34%), depression (n=381/392, 97.20%), chronic pain (n=305/310, 98.39%), insomnia/ sleeping problems (n=225/295, 86.44%), PTSD (n=247/270, 91.48%), headaches/ migraine (n=172/218, 78.90%), ADHD (n=82/123, 66.67%), bipolar disorder (n=79/89, 88.76%), and fibromyalgia (n=77/82, 93.90%). Most respondents were unsure/reported no change in blood pressure (n=93/162, 57.41%). A small percentage reported perceived worsening impacts on their conditions. Conclusion: Qualifying conditions and self-reported reasons for using MC aligned for most respondents. Yet, a notable proportion of respondents sought MC for broader treatment effects beyond those delineated by the officially recognized qualifying conditions in Florida, USA. Most patients perceived positive effects, including those with limited available evidence on efficacy.
