There was an increased risk of non-serious AEs with cannabinoids compared with placebo .
Conclusions There was moderate evidence to support cannabinoids in treating chronic , non-cancer pain at 2 weeks .
Similar results were observed at later time points , but the confidence in effect is low .
There is little evidence that cannabinoids increase the risk of experiencing serious AEs , although non-serious AEs may be common in the short-term period following use
Background For patients with chronic , non-cancer pain , traditional pain-relieving medications include opioids , which have shown benefits but are associated with increased risks of addiction and adverse effects .
Medical cannabis has emerged as a treatment alternative for managing these patients and there has been a rise in the number of r and omized clinical trials in recent years ; therefore , a systematic review of the evidence was warranted .
Objective To analyze the evidence surrounding the benefits and harms of medical cannabinoids in the treatment of chronic , non-cancer-related pain .
Do cannabis-based medicinal extracts have general or specific effects on symptoms in multiple sclerosis? A double-blind, randomized, placebo-controlled study on 160 patients
The objective was to determine whether a cannabis-based medicinal extract ( CBME ) benefits a range of symptoms due to multiple sclerosis ( MS ) . A parallel group , double-blind , r and omized , placebo-controlled study was undertaken in three centres , recruiting 160 out patients with MS experiencing significant problems from at least one of the following : spasticity , spasms , bladder problems , tremor or pain . The interventions were oromucosal sprays of matched placebo , or whole plant CBME containing equal amounts of delta-9- tetrahydrocannabinol ( THC ) and cannabidiol ( CBD ) at a dose of 2.5- 120 mg of each daily , in divided doses . The primary outcome measure was a Visual Analogue Scale ( VAS ) score for each patient ’s most troublesome symptom . Additional measures included VAS scores of other symptoms , and measures of disability , cognition , mood , sleep and fatigue . Following CBME the primary symptom score reduced from mean ( SE ) 74.36 ( 11.1 ) to 48.89 ( 22.0 ) following CBME and from 74.31 ( 12.5 ) to 54.79 ( 26.3 ) following placebo [ ns ] . Spasticity VAS scores were significantly reduced by CBME ( Sativex ) in comparison with placebo ( P- 0.001 ) . There were no significant adverse effects on cognition or mood and intoxication was generally mild
