CBD modulates contextual memories and responses to reward stimuli. Nonetheless, research on the impact of CBD on cocaine addiction-like behaviors is limited and requires further clarification. This study tested the hypothesis that CBD administration inhibits the acquisition and retrieval of cocaine-induced conditioned place preference (CPP) in adult male and female C57BL6\/J mice. We also ought to characterise a 5-day CPP protocol in these animals.<\/jats:p><\/jats:sec><jats:sec id=\"S0924270823000534_as2\"><jats:title>Methods:<\/jats:title><jats:p>Male and female C57BL\/6J mice were administered CBD (3, 10, and 30 mg\/kg) 30 minutes before cocaine (15 mg\/kg) acquisition of expression of CPP.<\/jats:p><\/jats:sec><jats:sec id=\"S0924270823000534_as3\"><jats:title>Results:<\/jats:title><jats:p>Cocaine induces a CPP in both female and male mice in the 5-day CPP protocol.
