Most trials showed improvement in symptoms associated with cannabinoids but these associations did not reach statistical significance in all trials .
There was an increased risk of short-term AEs with cannabinoids , including serious AEs .
Common AEs included dizziness , dry mouth , nausea , fatigue , somnolence , euphoria , vomiting , disorientation , drowsiness , confusion , loss of balance , and hallucination .
CONCLUSIONS AND RELEVANCE There was moderate- quality evidence to support the use of cannabinoids for the treatment of chronic pain and spasticity .
There was low- quality evidence suggesting that cannabinoids were associated with improvements in nausea and vomiting due to chemotherapy , weight gain in HIV infection , sleep disorders , and Tourette syndrome .
Cannabinoids were associated with an increased risk of short-term AEs
IMPORTANCE Cannabis and cannabinoid drugs are widely used to treat disease or alleviate symptoms , but their efficacy for specific indications is not clear .
OBJECTIVE To conduct a systematic review of the benefits and adverse events ( AEs ) of cannabinoids .
[Effect of the synthetic cannabinoid dronabinol on central pain in patients with multiple sclerosis--secondary publication].
Cannabinoids reduce allodynia/hyperalgesia in animal pain models , but few clinical studies evaluated the analgesic action in humans . We aim ed to evaluate the effect of delta-9-tetrahydrocannabinol ( dronabinol ) on central pain in MS patients . Twenty-four MS patients participated in a double-blind placebo-controlled crossover trial . Dronabinol reduced the spontaneous pain intensity significantly compared with placebo ( 4.0 ( 2.3 - 6.0 ) vs. 5.0 ( 4.0 - 6.4 ) , median ( 25th-75th percentiles ) , p = 0.02 ) . Though dronabinol 's analgesic effect is modest , its use should be evaluated considering the general difficulty in treating central pain
