Study Details

Brief summary:

The goal of the study is to learn if Epidiolex (cannabidiol) works as a additional pain medication in patients who have had orthopedic shoulder surgery. It is also to learn about safe dosages and identify any side effects after surgery.

Researchers will compare Epidiolex to a placebo solution to see if Epidiolex lowers pain after shoulder surgery.

Participants will:

  • track their pain and what medications they use every day in a provided pain diary. A researchers will call every seven days to check on the participant and diary.
  • Complete two short surveys. Once before surgery and once after.
  • Have bloodwork tested after surgery
