Rationale 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 [...]

Doi : 10.1371/journal.pone.0231583 Abstract Infections caused by antibiotic-resistant strains of Staphylococcus aureus have reached epidemic proportions globally. Our previous study showed antimicrobial effects of anandamide (AEA) and arachidonoyl serine (AraS) against methicillin (MET)-resistant S. aureus (MRSA) strains, proposing the therapeutic potential of these endocannabinoid/endocannabinoid-like (EC/EC-like) agents for the treatment of MRSA. Here, we investigated the potential synergism of combinations of AEA and AraS with different types of antibiotics against MRSA grown under planktonic growth or biofilm formation. The most effective [...]

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, [...]

Sottile, Ryan Vandrey, Adrienne J. Heinz, and Marcel O. Bonn-Miller Addictive Behaviors, 2017, 72, 14-20. Doi : 10.1016/j.addbeh.2017.03.006 Abstract Introduction : Medical cannabis is increasingly being used for a variety of health conditions as more states implement legislation permitting medical use of cannabis. Little is known about medical cannabis use patterns and motives among adults across the lifespan. Methods : The present study examined data collected at a medical cannabis dispensary in San Francisco, California. Participants included 217 medical cannabis patients who [...]

A Systematic Review and Meta-analysis Anees Bahji, MD; Callum Stephenson; Richard Tyo, BSocSc, RP; Emily R. Hawken, MSc, PhD; Dallas P. Seitz, MD, PhD JAMA Network Open, 2020, 3, (4), e202370. doi : 10.1001/jamanetworkopen.2020.2370 Abstract IMPORTANCE : Cannabis withdrawal syndrome (CWS)—a diagnostic indicator of cannabis use disorder—commonly occurs on cessation of heavy and prolonged cannabis use. To date, the prevalence of CWS syndrome has not been well described, nor have the factors potentially associated with CWS. OBJECTIVES : To estimate the prevalence of CWS among individuals with regular or dependent use of [...]

Whybrow Nikos K. Logothetis, and Gustavo Deco PNAS, 2020, 1-11 doi : 10.1073/pnas.1921475117 Remarkable progress has come from whole-brain models linking anatomy and function. Paradoxically, it is not clear how a neuronal dynamical system running in the fixed human anatomical connectome can give rise to the rich changes in the functional repertoire associated with human brain function, which is impossible to explain through long-term plasticity. Neuromodulation evolved to allow for such flexibility by dynamically updating the effectivity of the fixed anatomical connectivity. [...]

Cannabis use in pregnancy poses major health concerns for pregnant mothers and their developing children. Although studies on the short- and long-term consequences of prenatal cannabis exposure are increasing, findings have been inconsistent or difficult to interpret [...]

Due to this fact, MS produces a wide array of symptoms. Symptomatic therapy of one MS symptom can cause or worsen other unwanted symptoms (anticholinergics used for bladder dysfunction produce impairment of cognition, many MS drugs produce erectile dysfunction, etc.). Appropriate symptomatic [...]
