“Complementary and alternative medicine (CAM) is frequently used by Parkinson’s disease (PD) patients. We sought to provide information on CAM use and efficacy in PD patients in the Denver metro area with particular attention to cannabis use given its recent change in legal status.

Self-reported improvement related to the use of CAM was highest for massage, art therapy, music therapy, and cannabis.

While only 4.3% of our survey responders reported use of cannabis, it ranked among the most effective CAM therapies.

Conclusions. Overall, our cross-sectional study was notable for a high rate of CAM utilization amongst PD patients and high rates of self-reported efficacy across most CAM modalities.

Cannabis was rarely used in our population but users reported high efficacy, mainly for nonmotor symptoms.”
