Expected Effect of Cannabis by Symptom. Physicians were asked about the extent to which they expected cannabis would improve or worsen the following Parkinson's disease‐related symptoms: “improve” included the responses “much improved” and “little improved”; “worsen” included the responses “much worse” and “a little worse”; and “no effect” represented the response “no effect.” The majority of physicians expected that cannabis would lead to improvement in appetite, pain, nausea, and anxiety. Some positive effects also were expected for tremor, rigidity, and dyskinesias. The majority of physicians expected that cannabis would worsen fatigue, motivation, sleepiness, balance, forgetfulness, and hallucinations.
