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 [...]

Cannabis Withdrawal, Nicolas J. Schlienz and Ryan Vandrey, 2019

Cannabis Withdrawal Nicolas J. Schlienz and Ryan Vandrey I. D. Montoya, S. R. B. Weiss (eds.), Cannabis Use Disorders, https://doi.org/10.1007/978-3-319-90365-1_11   Introduction Drug withdrawal refers to a constellation of symptoms that occur following abrupt cessation of chronic drug use. Though drug withdrawal can occur from stopping use of medication, it is most often encountered within the context of illicit, non-medicinal, drug use. The withdrawal symptoms that emerge following extended and frequent use of abused drugs are a key feature of what define substance use disorders [4, 85]. Further, there is accumulating neurobiological evidence that withdrawal drives the maintenance of problematic substance misuse through a mechanism of [...]

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 [...]
