Marijuana Users May Be More Likely to Survive Acute Heart Failure Hospitalization , Steve Stiles, Medscape Medical News, September 16, 2019

Marijuana Users May Be More Likely to Survive Acute Heart Failure Hospitalization Steve Stiles Medscape Medical News © 2019 , September 16, 2019 PHILADELPHIA — There's sunny news, potentially, for patients with heart failure who are keen on cannabis. Hospitalized patients with a primary diagnosis of acute heart failure (HF) who say they are marijuana users are more likely to survive to discharge than nonusers, and they stay fewer days at less cost to the hospital, an observational study suggests. It may be only patients with heart failure and reduced ejection fraction (HFrEF) who benefit, not those with heart failure and preserved ejection fraction (HFpEF), [...]

Long-term Heavy Cannabis Use : implications for health education, Niall COGGANS et al., 2004

Long-term Heavy Cannabis Use : implications for health education Niall COGGANS, Phil DALGARNO, Lindsay JOHNSON & David SHEWAN Drugs : education, prevention and policy, 2004, Vol. 11, No. 4, 299–313   ABSTRACT There is growing evidence that cannabis can have negative effects on health. While the ongoing debate about the nature and duration of these effects recognizes mild cognitive impairment, the evidence for irreversibility of cognitive impairment and causal links with psychiatric illness is not conclusive. There is undoubtedly potential for impairment of respiratory functioning, but that will depend on lifetime load and in most cases is confounded with tobacco smoking. There is a [...]

The association between cannabis use and psychiatric comorbidity in people with personality disorders : A population-based longitudinal study, Nadav Shalita et al., 2019

The association between cannabis use and psychiatric comorbidity in people with personality disorders : A population-based longitudinal study Nadav Shalita, Jürgen Rehmb, Shaul Lev-Ran Psychiatry Research, 2019, 278, 70–77 https://doi.org/10.1016/j.psychres.2019.05.041 A B S T R A C T Both personality disorders (PD) and cannabis use are highly comorbid with various psychiatric disorders. While previous research indicates specific interactions between cannabis use and schizotypal PD associated with schizophrenia, research into cannabis use among individuals with other PDs and the development of several additional psychiatric disorders is scarce. We explored the prevalence and incidence of psychiatric disorders among individuals with PDs who use cannabis, and whether individuals [...]

Acute effects of delta 9-tetrahydrocannabinol (THC) on resting state brain function and their modulation by COMT genotype, Matthijs G. Bossong et al., 2019

Acute effects of delta-9-tetrahydrocannabinol (THC) on resting state brain function and their modulation by COMT genotype Matthijs G. Bossong, Hendrika H. van Hell, Chris D. Schubart, Wesley van Saane, Tabitha A. Iseger, Gerry Jager, Matthias J.P. van Osch, J. Martijn Jansma, René S. Kahn, Marco P. Boks, Nick F. Ramsey European Neuropsychopharmacology, 2019, 13, 56, 1–11 https://doi.org/10.1016/j.euroneuro.2019.03.010   Abstract Cannabis produces a broad range of acute, dose-dependent psychotropic effects. Only a limited number of neuroimaging studies have mapped these effects by examining the impact of cannabis on resting state brain neurophysiology. Moreover, how genetic variation influences the acute effects of cannabis on resting state brain function [...]

Nabiximols combined with motivational enhancement/cognitive behavioral therapy for the treatment of cannabis dependence : A pilot randomized clinical trial Jose M. Trigo, Alexandra Soliman, Lena C. Quilty, Benedikt Fischer, JuÈrgen Rehm, Peter Selby, Allan J. Barnes11¤a, Marilyn A. Huestis, Tony P. George, David L. Streiner, Gregory Staios, Bernard Le Foll PLoS ONE, 2018, 13, (1), e0190768. https://doi.org/10.1371/journal.pone.0190768   Abstract Background The current lack of pharmacological treatments for cannabis use disorder (CUD) warrants novel approaches and further investigation of promising pharmacotherapy. We previously showed that nabiximols (27 mg/ml Δ9-tetrahydrocannabinol (THC)/ 25 mg/ml cannabidiol (CBD), Sativex®) can decrease cannabis withdrawal symptoms. Here, we assessed in a pilot study the [...]
