Conclusions and Relevance Cannabinoid drugs may prevent the onset of pain by producing small increases in pain thresholds but may not reduce the intensity of experimental pain already being experienced ; instead , cannabinoids may make experimental pain feel less unpleasant and more tolerable , suggesting an influence on affective processes .
Cannabis-induced improvements in pain-related negative affect may underlie the widely held belief that cannabis relieves pain
Importance Cannabinoid drugs are widely used as analgesics , but experimental pain studies have produced mixed findings .
The analgesic properties of cannabinoids remain unclear .
Objective To conduct a systematic review and meta- analysis of the association between cannabinoid drug administration and experimental pain outcomes in studies of healthy adults .
The Cochrane Collaboration’s tool for assessing risk of bias in randomised trials
Flaws in the design , conduct , analysis , and reporting of r and omised trials can cause the effect of an intervention to be underestimated or overestimated . The Cochrane Collaboration ’s tool for assessing risk of bias aims to make the process clearer and more
