Regier, Albert Garcia-Romeu, Matthew W. Johnson, Peter S. Hendricks International Journal of Drug Policy, 2021, Doi : 10.1016/j.drugpo.2021.103380 a b s t r a c t Several pilot studies have provided evidence supporting the potential of classic psychedelics like psilocybin in the treatment of substance use disorders (SUDs). If larger trials confirm efficacy, classic psychedelic-assisted psychotherapy may eventually be integrated into existing addiction treatments such as cognitive behavioral therapy, contingency management, and medication-assisted therapies. Many individuals seeking treatment for SUDs also join twelve-step [...]

Cannabis-derived psychoactive compounds such as Δ9-tetrahydrocannabinol and synthetic cannabinoids directly interact with the reward system and thereby have addictive properties. Cannabinoids induce their reinforcing properties by an increase in tonic dopamine levels through a cannabinoid type 1 (CB1) receptor–dependent mechanism within the ventral tegmental area. Cues that are conditioned [...]

Doi : 10.3389/fphar.2021.626010 Drug treatments available for the management of substance use disorders (SUD) present multiple limitations in efficacy, lack of approved treatments or alarming relapse rates. These facts hamper the clinical outcome and the quality of life of the patients supporting the importance to develop new pharmacological agents. Lately, several reports suggest that cannabidiol (CBD) presents beneficial effects relevant for the management of neurological disorders such as epilepsy, multiple sclerosis, Parkinson’s, or [...]

García-Gutiérrez, Ani Gasparyan, Daniela Navarro and Jorge Manzanares Biomolecules, 2021, 11, 1556, 1-18. Doi : 10.3390/biom11111556 Abstract The pharmacological modulation of the cannabinoid receptor 2 (CB2r) has emerged as a promising potential therapeutic option in addiction. The purpose of this review was to determine the functional involvement of CB2r in the effects produced by drugs of abuse at the central nervous system (CNS) level by assessing evidence from preclinical and clinical studies. In rodents, several reports suggest the functional involvement of CB2r in the effects produced by drugs of abuse such [...]

Doi : 10.1016/j.tins.2006.01.008 Recent studies have shown that the endocannabinoid system is involved in the common neurobiological mechanism underlying drug addiction. This system participates in the primary rewarding effects of cannabinoids, nicotine, alcohol and opioids, through the release of endocannabinoids in the ventral tegmental area. Endocannabinoids are also involved in the motivation to seek drugs by a dopamine-independent mechanism, demonstrated for psychostimulants and opioids. The endocannabinoid system also participates in the common mechanisms underlying relapse to drugseeking behaviour by mediating the motivational effects [...]

Carai, Giancarlo Colombo, and Gian Luigi Gessa Cannabis and Cannabinoid Research, 2021, Doi : 10.1089/can.2020.0132 Abstract Introduction : Cannabidiol (CBD) is a major cannabinoid extracted from Cannabis sativa with no abuse potential. Data from recent rodent studies suggest that amelioration of alcohol-motivated behaviors may be one of the numerous pharmacological effects of CBD. This study was designed to contribute to this research, assessing the effect of CBD on operant oral alcohol self-administration in selectively bred Sardinian alcohol preferring (sP) rats, a validated animal model of excessive alcohol consumption.

Di : 10.1007/s00213-020-05477-0 Abstract Rationale : The regular consumption of very small doses of psychedelic drugs (known as microdosing) has been a source of growing media and community attention in recent years. However, there is currently limited clinical and social research evidence on the potential role of microdosing as therapies for mental and substance use disorders. Objectives : This paper examined subjective experiences of microdosing psychedelics to improve mental health or to cease [...]
