Medical Cannabis Use Rising Among Older Adults, Pauline Anderson, Medscape Medical News, 2021

Medical Cannabis Use Rising Among Older Adults Pauline Anderson Medscape Medical News ©March 22, 2021   More individuals are using medical cannabis, but the increase appears to be more pronounced among seniors, new research suggests. Results of a large Canadian survey study show that the proportion of older users among total users increased from 17.6% before 2017 to 26.7% in 2018 and 31.2% in 2019. The proportion of older users was 22.7% in 2020, but there were fewer participants in this latest sample (8869 in 2019 and 5644 in 2020). The majority of older respondents reported that they use cannabis to relieve pain and prefer cannabidiol [...]

Positive expectations predict improved mental-health outcomes linked to psychedelic microdosing, L.S. Kaertner et al., 2021

Positive expectations predict improved mental-health outcomes linked to psychedelic microdosing, KAERTNER L.S., STEINBORN M.B., KETTNER H., SPRIGGS M.J., ROSEMAN L., BUCHBORN T., BALAET M., TIMMERMANN C., ERRITZOE D., CARHARDT-HARRIS R.L. : Nature, 2021, 11, 1941 Doi : 1038/s41598-021-81446-7   Abstract Psychedelic microdosing describes the ingestion of near-threshold perceptible doses of classic psychedelic substances. Anecdotal reports and observational studies suggest that microdosing may promote positive mood and well-being, but recent placebo-controlled studies failed to find compelling evidence for this. The present study collected web-based mental health and related data using a prospective (before, during and after) design. Individuals planning a weekly microdosing regimen completed surveys at strategic [...]

Repeated Ketamine Infusions Linked to Rapid Relief of PTSD, Deborah Brauser, Medscape.com, 2021

Repeated Ketamine Infusions Linked to Rapid Relief of PTSD Deborah Brauser Medscape. com, January 18, 2021 Medscape Medical News © 2021 www.medscape.com/viewarticle/944282_print   Repeated intravenous infusions of ketamine provide rapid relief for patients with posttraumatic stress disorder (PTSD), new research suggests. In what investigators are calling the first randomized controlled trial of repeated ketamine administration for chronic PTSD, 30 patients received six infusions of ketamine or midazolam (used as a psychoactive placebo) over 2 consecutive weeks. Between baseline and week 2, those receiving ketamine showed significantly greater improvement than those receiving midazolam. Total scores on the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) for the first group were almost 12 points [...]

The experimental effects of psilocybin on symptoms of anxiety and depression : A meta-analysis, Simon B. Goldberg et al, 2020

The experimental effects of psilocybin on symptoms of anxiety and depression : A meta-analysis Simon B. Goldberg, Brian T. Pace, Christopher R. Nicholas, Charles L. Raison, Paul R. Hutson Psychiatry Research, 2020, 284,  112749 Doi : 10.1016/j.psychres.2020.112749   A B S T R A C T The current meta-analysis examined the effects of psilocybin in combination with behavioral interventions on anxiety and depression in samples with elevated symptoms. Across four studies (one uncontrolled; three randomized, placebo-controlled; N = 117), within-group pre-post and pre-follow-up effects on anxiety and depression were large (Hedges’ gs=1.16 to 1.47) and statistically significant. Across three placebo-controlled studies, pre-post placebo-controlled effects were also [...]

Development of Ketamine Administration as a Treatment for Chronic PTSD, Abigail B. Collins et al., 2020

Development of Ketamine Administration as a Treatment for Chronic PTSD Abigail B. Collins, BS; Sarah B. Rutter, MA; and Adriana Feder, MD Psychiatric Annals, 2020, 50, (2), 68-76. doi : 10.3928/00485713-20200109-01   ABSTRACT Posttraumatic stress disorder (PTSD) is a highly prevalent, chronic, and dis-abling condition for which currently available pharmacotherapies are insuf-ficiently effective. Ketamine, which is a glutamate N-methyl-D-aspartate (NMDA) receptor antagonist, has emerged as a promising and rapid-act-ing novel treatment intervention for this disorder. Findings from a proof-of-concept, randomized, controlled cross-over study of single-dose intravenous ketamine administration (compared to single-dose midazolam) in patients with chronic PTSD suggest that ketamine is associated with rapid improvement in [...]
