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 .
Cannabidiol enhances anandamide signaling and alleviates psychotic symptoms of schizophrenia
Cannabidiol is a component of marijuana that does not activate cannabinoid receptors , but moderately inhibits the degradation of the endocannabinoid an and amide . We previously reported that an elevation of an and amide levels in cerebrospinal fluid inversely correlated to psychotic symptoms . Furthermore , enhanced an and amide signaling let to a lower transition rate from initial prodromal states into frank psychosis as well as postponed transition . In our translational approach , we performed a double-blind , r and omized clinical trial of cannabidiol vs amisulpride , a potent antipsychotic , in acute schizophrenia to evaluate the clinical relevance of our initial findings . Either treatment was safe and led to significant clinical improvement , but cannabidiol displayed a markedly superior side-effect profile . Moreover , cannabidiol treatment was accompanied by a significant increase in serum an and amide levels , which was significantly associated with clinical improvement . The results suggest that inhibition of an and amide deactivation may contribute to the antipsychotic effects of cannabidiol potentially representing a completely new mechanism in the treatment of schizophrenia
