"CBD, which is nonhedonic, can reduce heroin-seeking behavior after, for example, cue-induced reinstatement. This was shown in an animal heroin self-administration study, where mice received 5 mg/kg CBD i.p. injections. The observed effect lasted for 2 weeks after CBD administration and could normalize the changes seen after stimulus cue-induced heroin seeking (expression of AMPA, GluR1, and CB1R). In addition, the described study was able to replicate previous findings showing no CBD side effects on locomotor behavior.23"
