Abstract:
Background: β-caryophyllene (BCP) is a natural bicyclic sesquiterpene found in Cannabis
and other plants. BCP is currently used as a food additive, although pharmacological studies suggest
its potential therapeutic application for the treatment of certain brain disorders. The mechanisms of
action of BCP remain uncertain, possibly including full agonism at the cannabinoid CB2 receptor
(CB2R).
Objective: The study aims to investigate BCP’s potential as a new drug for the treatment of substance
use disorders by reviewing preclinical studies with animal models.
Results: BCP has been investigated in behavioral paradigms, including drug self-administration, conditioned
place preference, and intracranial self-stimulation; the drugs tested were cocaine, nicotine, alcohol,
and methamphetamine. Remarkably, BCP prevented or reversed behavioral changes resulting
from drug exposure. As expected, the mechanism of action entails CB2R activation, although this is
unlikely to constitute the only molecular target to explain such effects. Another potential target is the
peroxisome proliferator-activated receptor.
Conclusion: Preclinical studies have reported promising results with BCP in animal models of substance
use disorders. Further research, including studies in humans, are warranted to establish its therapeutic
potential and its mechanisms of action.
