Canadian Veterans’ Medical Cannabis Use Linked to Key Health Factors

AI Insight

This cross-sectional study of 1,289 Canadian veterans found that 18.4% were authorized for cannabis for medical purposes (CMP) reimbursement through Veterans Affairs Canada. Key factors associated with authorization included younger age, unemployment due to inability to work, post-traumatic stress disorder (PTSD), anxiety disorders, and severe pain. The study revealed different patterns of CMP authorization depending on whether veterans had PTSD, with unemployment and severe pain being consistent factors across both groups.


The findings highlight that Canadian veterans using medical cannabis tend to have complex health profiles involving mental health conditions, chronic pain, and functional impairment. Understanding these patterns can inform clinical decision-making and policy development regarding medical cannabis programs for veterans, though longitudinal research is needed to assess actual effectiveness and safety.

Background Evidence on factors associated with cannabis for medical purposes (CMP) authorizations among Veterans Affairs Canada (VAC) clients remains limited and inconsistent, particularly concerning mental health and posttraumatic stress disorder (PTSD), a leading indication for use. We investigated demographic, clinical and service characteristics associated with VAC authorizations for CMP reimbursement. Method We linked VAC administrative CMP program data with responses from the 2019 Life After Services Studies cross-sectional survey of Regular Force veterans released between 1998 and 2018. Multivariable logistic regressions examined associations between CMP reimbursement (yes/no) and demographic, clinical and well-being factors, with analyses stratified by PTSD status. Results Among 1,289 respondents (weighted n=33,131), 18.4% were authorized for CMP reimbursement. Younger age (<40 vs. [≥]60 years: OR 4.78, 95% CI: 2.24-10.21), unemployment with inability to work vs. employed (OR 3.10, 95% CI: 1.78-5.40), land service vs. air (OR 2.07, 95% CI: 1.22-3.50), PTSD (OR 2.81, 95% CI: 1.69-4.66), anxiety (OR 2.32, 95% CI: 1.45-3.70), and severe pain vs. no pain (OR 3.61, 95% CI: 1.97-6.60) were independently associated with authorization. Unemployment and severe pain were consistent correlates across PTSD strata. Among those without PTSD, younger age, multiple physical conditions, and frequent mental health visits were significant; among those with PTSD, shorter service, witnessing destruction, and suicidal ideation were additional factors. Conclusions CMP authorization patterns among Canadian veterans reflect the intersection of mental health, pain, and functional impairment, with variation by PTSD status. These findings underscore the need for longitudinal research on CMP mechanisms, effectiveness and safety.
