BACKGROUND: The current study aims to evaluate the rates and associations of cannabis use among Canadian adults with cancer (2007-2016).
METHODS: Canadian Community Health Survey (CCHS) (2007-2016) was accessed and adult participants with who answered yes to the question "Do you have cancer?" and who have complete information about cannabis use were included. Multivariable logistic regression was used to clarify the factors associated with cannabis use. Another multivariable logistic regression analysis was used to evaluate the impact of cannabis use on suicidal ideation.
RESULTS: A total of 4667 participants who currently have cancer were included in the current analysis. The rate of cannabis use increased throughout the study (34.4% in 2015-2016 versus 27.7% in 2007-2008). In a multivariable analysis for factors associated with cannabis use among cancer patients, the following factors were associated with cannabis use: younger age (OR: 3.64; 95% CI: 2.27-5.86; P<0.01); male sex (OR: 2.11; 95% CI: 1.80-2.48; P<0.01); white race (OR: 2.02; 95% CI: 1.46-2.78; P<0.01); single status (OR for married versus single: 0.38; 95% CI: 0.29-0.50; P<0.01) and higher income (OR for income < 20,000 versus income ≥ 80,000: 00.74; 95% CI: 0.56-0.99; P=0.04). In another multivariable analysis for factors associated with suicidal ideation, the history of cannabis use was associated with an increased probability of suicidal ideation (OR: 2.03; 95% CI: 1.47-2.87; P<0.01).
CONCLUSIONS: Within this study cohort of Canadian adults with current cancer diagnosis, cannabis use is not uncommon. A history of cannabis use is associated with younger age, male sex, white race, non-married status, and higher income.
