Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The goal of this observational study is to learn how medical cannabis (MC) affects pain and the use of opioid pain medications. Participants who have chronic pain and use prescribed opioid pain medication will opt-in to using MC or not for the 3-month study. Participants who are certified in Pennsylvania will purchase specific medical cannabis products at a reduced cost from a partnering medical cannabis dispensary monthly. All participants will complete baseline, daily, and monthly assessments to observe changes across groups.
