Single Shot of Ketamine May Herald 'Last Call' for Problem Drinking Deborah Brauser Medscape, December 11, 2019 Medscape Medical News © 2019 https://www.medscape.com/viewarticle/922460?src=wnl_tp10n_200116_mscpedit&uac=292598PZ&impID=2238619&faf=1 An experimental treatment that includes a single infusion of ketamine may lead to long-term improvement in problem drinking, new research suggests. In an study of 90 heavy drinkers, those who received a single dose of intravenous (IV) ketamine plus cognitive behavioral therapy (CBT) that focused on reactivating drinking-related "maladaptive reward memories" (MRMs) significantly curbed the urge to drink and reduced alcohol intake compared with those who received the ketamine alone or a placebo infusion. In addition, the combination group reduced their average weekly alcohol consumption by [...]

Abstract The butyl homologues of Δ9-tetrahydrocannabinol, Δ9-tetrahydrocannabutol (Δ9-THCB), and cannabidiol, cannabidibutol (CBDB), were isolated from a medicinal Cannabis sativa variety (FM2) inflorescence. Appropriate spectroscopic and spectrometric characterization, including NMR, UV, IR, ECD, and HRMS, was carried out on both cannabinoids. The chemical structures and absolute configurations of the isolated cannabinoids were [...]

Doi : 10.1590/1516-4446-2019-4104 Depression is among the most important contributors to global disability and suicidal deaths. Available antidepressants are usually selective inhibitors of serotonin and norepinephrine uptake, which need weeks of daily intake before therapeutic effects appear, have limited efficacy for many patients, and induce significant adverse reactions after prolonged use. Therefore, recent research has focused on finding new antidepressant compounds that are fast-acting, more effective, and less toxic. The article recently published by da Silva et al. in the [...]

Doi : 10.1101/866814 Abstract Psychedelic agonists of serotonin receptors induce neural plasticity and synaptogenesis, but their potential to enhance learning remains uncharted. Here we show that a single dose of d-LSD, a potent serotonergic agonist, increased novel object preference in young and adult rats several days after treatment. d- LSD alone did not increase preference [...]

Previous use of recreational cannabis was not associated with such features, suggesting that any deleterious effects may not be permanent. "These are early data which included a relatively small group of regular cannabis users, and the changes we detected were subtle," lead author Mohammed Y.
