This study will examine how medical cannabis use affects opioid analgesic use, with particular attention to THC/CBD (Tetrahydrocannibinol/Cannabidiol) content and adverse events. We will enroll adults with (a) severe or chronic neuropathic or joint pain, (b) prescribed opioid analgesic use, (c) active certification for medical cannabis, and (d) intends to have soft gel capsule products dispensed at Vireo (medical cannabis dispensary) (including a high THC:low CBD product, an equal THC:CBD (Tetrahydrocannibinol:Cannabidiol) product, and a low THC:high CBD product). Over the 14 weeks, data sources will include questionnaires; medical, pharmacy, and Prescription Monitoring Program (PMP) records; and urine samples. The primary independent variable will be type of soft gel capsule product, and the primary outcome will be cumulative opioid analgesic dose.
The study will examine how medical cannabis use affects opioid analgesic use. This landmark study will be among the first to examine the effect of medical cannabis with different THC/CBD (Tetrahydrocannibinol/Cannabidiol) content on opioid use as well as adverse events.
