Involvement of the endocannabinoid system in drug addiction, Rafael Maldonado, Olga Valverde and Fernando Berrendero Trends in Neurosciences, 2006, 29, (4), 225-232. 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 [...]

Doi : 10.1089/can.2018.0022 Abstract Introduction : The opioid epidemic has become an immense problem in North America, and despite decades of research on the most effective means to treat opioid use disorder (OUD), overdose deaths are at an all-time high, and relapse remains pervasive. Discussion : Although there are a number of FDA-approved opioid replacement therapies and maintenance medications to help ease the severity of opioid withdrawal symptoms and aid in relapse prevention, these medications are not risk free nor are they successful [...]

McCall and Brian J. Piper International Journal of Environmental Research and Public Health, 2020, 17, 3251 doi : 10.3390/ijerph17093251 Abstract : There have been dynamic changes in prescription opioid use in the US but the state level policy factors contributing to these are incompletely understood. We examined the association between the legalization of recreational marijuana and prescription opioid distribution in Colorado. Utah and Maryland, two states that had not legalized recreational marijuana, were selected for comparison. Prescription data reported to [...]
Lire la suiteRationale for cannabis-based interventions in the opioid overdose crisis Philippe Lucas Harm Reduction Journal, 2017, 14, 58 Doi : 10.1186/s12954-017-0183-9 Abstract Background : North America is currently in the grips of a crisis rooted in the use of licit and illicit opioid-based analgesics. Drug overdose is the leading cause of accidental death in Canada and the US, and the growing toll of opioid-related morbidity and mortality requires a diversity of novel therapeutic and harm reduction-based interventions. Research suggests that increasing adult access to both medical and recreational cannabis has significant positive impacts on public health and safety as a result of substitution effect. Observational and [...]
Lire la suiteWhat does the ecological and epidemiological evidence indicate about the potential for cannabinoids to reduce opioid use and harms ? A comprehensive review Gabrielle Campbell, Wayne Hall and Suzanne Nielsen International Review of Psychiatry, 2018, 1-16. Doi : 10.1080/09540261.2018.1509842 ABSTRACT Pre-clinical research supports that cannabinoids reduce opioid dose requirements, but few studies have tested this in humans. This review evaluates ecological and epidemiological studies that have been cited as evidence that medical cannabis use may reduce opioid use and opioidrelated harms. Medline and Embase were searched for relevant articles. Data were extracted on study setting, analyses approach, covariates, and outcomes. Eleven ecological and 14 epidemiological [...]

Doi : 10.1016/j.pmn.2019.06.009 a b s t r a c t Background : Cannabis has been linked to reduced opioid use, although reasons for cannabis use among adults prescribed opioids are unclear. Aims : The purpose of this study was to determine whether motivations for cannabis use differ between adults prescribed opioids for persistent pain versus those receiving opioids as medication-assisted treatment for opioid use disorder. Design : A cross-sectional survey design was used. Participants : Adults prescribed opioids for persistent pain (n [...]

A B S T R A C T Background : Increasingly, states are legalizing cannabis for recreational use. Improved accessibility may allow adults with pain to use cannabis more liberally. Greater understanding is needed about how adults with pain perceive the effects of cannabis, particularly those who also use opioid analgesics. Purpose : To examine the perceived effects of cannabis among adults who have [...]
Lire la suiteOpioid mortality following implementation of medical marijuana programs (1999-2017) in the United States Daniel E. Kaufman, Asawer M. Nihal, Janan D. Leppo, Kelly M. Staples, Kenneth L. McCall, Brian J. Piper BioRxiv preprint, June 14, 2019. Doi : 10.1101/670059 Abstract The United States is in the midst of an opioid overdose epidemic. A prior report using the Center for Disease Control’s Wide-ranging Online Data for Epidemiologic Research (WONDER) database discovered that opioid overdoses decreased by 24.8% from 1999 to 2010 in states with medical cannabis (MC+) relative to those without (MC-). The present study evaluated any differences following MC legislation on WONDER reported opioid overdoses, [...]

Bigand, Oladunni Oluwoye,Celestina Barbosa-Leiker, MaryLee A. Roberts Addictive Behaviors, 2017, 30 p. doi : 10.1016/j.addbeh.2017.10.012 Abstract Introduction : Adults in Medication-Assisted Treatment (MAT) for opioid addiction are at risk for substance use relapse and opioid overdose. They often have high rates of cannabis use and comorbid symptoms of pain, depression, and anxiety. Low levels of self-efficacy (confidence that one can self-manage symptoms) are linked to higher symptom burdens and increased substance use. The effects of cannabis use on symptom management [...]

Il s’agit d’éviter autant que possible de charger encore plus l’activité des urgences, des services hospitaliers et d’une médecine et pharmacie de ville déjà en surchauffe, en réduisant la transmission virale chez des personnes présentant toutes des troubles chroniques et qui seront donc autant de situations sévères en cas de contamination. Nos actions convergent [...]
