“The purpose of the study was to better understand why patients with history of head and neck cancer (HNC) treated with radiotherapy are using medical marijuana (MM).

RESULTS:

There was a 100 % response rate. Median time from treatment was 45 months (21-136 months). Most patients smoked marijuana (12 patients), while others reported ingestion (4 patients), vaporizing (3 patients), and use of homemade concentrated oil (1 patient). Six patients reported prior recreational marijuana use before diagnosis. MM provided benefit in altered sense, weight maintenance, depression, pain, appetite, dysphagia, xerostomia, muscle spasm, and sticky saliva.

CONCLUSIONS:

HNC patients report MM use to help with long-term side effects of radiotherapy.”
