- What is the clinical effectiveness of long-term nabilone use?
- What is the evidence for the safety and harms of long-term nabilone use?
Based upon one systematic review and four RCTs, nabilone was more effective than placebo in improving PTSD-associated nightmares and quality of life, neuropathic pain related to MS and diabetes, and spasticity due to spinal cord injury for four to nine weeks of treatment. Adverse events were generally not considered serious. However, the generalizability of these results is uncertain given the limited number of participants in each trial.
