<unk>  is used to treat nausea and vomiting in people under chemotherapy.<unk>  has shown modest effectiveness in relieving fibromyalgia. A 2011 systematic review of cannabinoids for chronic pain determined there was evidence of safety and modest efficacy for some conditions. The main settings that have seen published clinical trials of<unk>  include movement disorders such as parkinsonism, chronic pain, dystonia and spasticity neurological disorders, multiple sclerosis, and the nausea of cancer chemotherapy.<unk>  is also effective in the treatment of inflammatory bowel disease, especially ulcerative colitis. In one study of current daily users of cannabis, oral<unk>  at 4, 6, and 8 mg produced sustained and dose-dependent mood elevation and psychomotor slowing comparable to 10 or 20 mg oral dronabinol (THC).<unk>  had a slower onset of peak action and a greater dose-dependence of effects, which the investigators attributed to greater bioavailability. A study comparing<unk>  with metoclopramide, conducted before the development of modern 5-HT3 antagonist anti-emetics such as ondansetron, revealed that patients taking cisplatin chemotherapy preferred metoclopramide, while patients taking carboplatin preferred<unk>  to control nausea and vomiting.<unk>  is sometimes used for nightmares in post-traumatic stress disorder, but there have not been studies longer than nine weeks, so effects of longer-term use are not known.<unk>  has also been used for medication overuse headache.
