Cannabinoids and the endocannabinoid system in reward processing and addiction: from mechanisms to interventions Rainer Spanagel, PhD Dialogues in Clinical Neuroscience, 2020, 22, (3), 241-250. doi : 10.31887/DCNS.2020.22.3/rspanagel The last decades have seen a major gain in understanding the action of cannabinoids and the endocannabinoid system in reward processing and the development of addictive behavior. 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 [...]

Or, les consommations de substances addictives dépendent de l’équilibre dynamique permanent qui existe entre un sujet et son environnement. Beaucoup se demandent donc quel sera l’impact du confinement sur les consommations d’alcool, de tabac, ou d’autres drogues, dans la population française en générale, mais aussi chez les sujets les plus vulnérables, qui ont, [...]

BARSUGLIA, MARLEY WINDHAM-HERMAN, MARTA LYNCH and MARTIN POLANCO Journal of Psychedelic Studies, 2017, 1, (2), pp. 65–73 DOI: 10.1556/2054.01.2017.009 Background and aims : Very few studies have reported the effectiveness of ibogaine as a treatment for chronic opioid use. Therefore, this study evaluated the acute subjective effects of ibogaine, outcomes on problematic opioid consumption, and the long-term associations with psychological functioning. Methods : Using online data collection, 88 patients who received ibogaine treatment in Mexico between 2012 and 2015 completed our survey. Results : [...]

The types of drugs discussed in this context focus on those assumed to be the most ‘addictive’ – heroin and cocaine – to those less well-known but potentially more hazardous to use without [...]
