Recruitment Challenges for Cannabis Clinical Trials – Emily Lindley, PhD & Rachael Rzasa Lynn, MD

August 20, 2025

Dr. Emily Lindley is Assistant Professor of Orthopedics and Director of the Colorado Cannabis Research Consortium. Her team’s research aims to identify non-opioid alternatives for the treatment of chronic musculoskeletal pain. One such alternative that has gained increased recognition in recent years is medical cannabis, and her lab is currently studying the health effects of cannabis and cannabinoids for chronic musculoskeletal pain.

Dr. Rachael Rzasa Lynn is a board certified in pain medicine physician and is an Associate Professor in the Department of Anesthesiology at the University of Colorado, where she is the Associate Program Director for the Pain Medicine Fellowship. Her research includes investigations in opioid pharmacology and the use of cannabis for chronic pain.

Emily and Rachael co-authored a poster presented at the most recent ICRS conference titled, Recruitment Challenges in Clinical Studies of Cannabis

During our conversation, we discussed:

  • How recruitment for cannabis clinical trials differs from traditional clinical trials
  • Why prior experience with cannabis is considered a negative for patient recruitment
  • How legal concerns and stigma can deter cannabis-naive patients from enrolling
  • Why the particiapnt drop out rate is higher in cannabis trials
  • How rescheduling may affect patient recruitment future trials
