“Drug addiction is a chronically relapsing disorder characterized by the compulsive desire to use drugs and a loss of control over consumption.
Cannabidiol (CBD), the second most abundant component of cannabis, is thought to modulate various neuronal circuits involved in drug addiction.
The goal of this systematic review is to summarize the available preclinical and clinical data on the impact of CBD on addictive behaviors.
MEDLINE and PubMed were searched for English and French language articles published before 2015. In all, 14 studies were found, 9 of which were conducted on animals and the remaining 5 on humans.
A limited number of preclinical studies suggest that CBD may have therapeutic properties on opioid, cocaine, and psychostimulant addiction, and some preliminary data suggest that it may be beneficial in cannabis and tobacco addiction in humans.
Further studies are clearly necessary to fully evaluate the potential of CBD as an intervention for addictive disorders.”

“CBD is an exogenous cannabinoid that acts on several neurotransmission systems involved in addiction. Animal studies have shown the possible effects of CBD on opioid and psychostimulant addiction, while human studies presented some preliminary evidence of a beneficial impact of CBD on cannabis and tobacco dependence. CBD has several therapeutic properties on its own that could indirectly be useful in the treatment of addiction disorders, such as its protective effect on stress vulnerability and neurotoxicity… The dreadful burden of substance-use disorder worldwide, combined with the clear need for new medication in the addiction field, justifies the requirement of further studies to evaluate the potential of CBD as a new intervention for addictive behaviors.” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4444130/
