Marijuana

New research lends support to a controversial hypothesis dubbed the entourage effect, which claims the medical benefits of cannabis are not due to single cannabinoids such as THC or CBD, but rather the interactions between various compounds in the plant.

A new study presents results from one of the first placebo-controlled trials exploring the influence of CBD on sensations of acute pain. The mixed results suggest CBD may reduce feelings of unpleasantness, helping one tolerate pain more effectively.

How long is a person’s ability to safely drive impaired after consuming cannabis? A meta-analysis suggests intoxication spans anywhere from three to 10 hours, raising questions over some roadside tests detecting traces of THC days after consumption.

New research suggests cannabis use can be linked to higher rates of "rebound headaches" in migraine sufferers. The research is observational and retrospective, but it is yet another finding questioning how helpful cannabis is for chronic migraine patients.

Canadian researchers are reporting the results of a clinical trial testing the efficacy of CBD in helping cocaine addicts kick the habit. The results suggest CBD does not reduce cocaine cravings or help prevent relapse into addiction.

A team of scientists has demonstrated a novel microencapsulation method designed to improve the absorption and bioavailability of CBD. Animal tests suggest the new method increases peak concentrations of CBD in the brain by 300% compared to CBD oil.

A study into the effects of cannabis on driving in a real-world context has found CBD alone does not impair driving ability. The landmark finding promises to be invaluable in guiding road safety regulations as cannabis laws shift across the globe.

A progressive wave of drug reforms have been passed by US voters, including four states legalizing recreational marijuana, one state decriminalizing natural psychedelics, and Oregon decriminalizing all drugs and legalizing psilocybin psychotherapy.

Some people find their symptoms of OCD dramatically drop after smoking cannabis, according to a new study. The improvements may only be beneficial in the short-term however, and more research is needed to understand the long-term effect of cannabis use on OCD.

Positive results from the world’s first clinical trial testing the potential for cannabidiol (CBD) to treat cannabis addiction suggest daily use of medical-grade CBD is both safe and effective at reducing problematic cannabis consumption.

New research is offering the first clinical trial insights into microdosing THC to treat chronic pain. The results of the small trial suggest tiny doses of THC may confer clinically apparent reductions in pain without inducing psychoactive effects.

A study has found smoking high-THC marijuana or concentrates does not result in greater levels of intoxication. The research adds weight to a body of evidence suggesting proposed roadside THC tests may not correlate with driving impairment.
