A study analyzing self-reports from patients with fibromyalgia who were referred to a tertiary care pain center indicate that 13% used cannabinoids to manage their pain. Among these patients, 80% used marijuana, 24% used prescription cannabinoids, and 3% used both. Users tended to be unemployed and receiving disability payments. Marijuana use was associated with:
Unstable mental illness (36%).
Male gender (26%).
Opioid drug-seeking behavior (17%).
