Marijuana

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.

With legal recreational cannabis use spreading across North America there is a debate over what the minimum age for consumption should be. A new study from Canadian researchers suggests 19 is the optimal age to set for recreational use of the drug.

Results from the world's first placebo-controlled clinical trial testing the efficacy of medicinal cannabis for chronic insomnia reveal statistically significant, and dose responsive, improvements to sleep quality using a novel CBD/THC formulation.

A study tracking the potency of cannabis products found most medical marijuana is stronger than it needs to be for pain relief. The research suggests high THC levels are unnecessary for medical uses and can increase the risk of negative side effects.

A team of researchers from King’s College London has, for the first time, imaged the brains of patients with psychosis under the influence of CBD. The study demonstrates the anti-psychotic potential of CBD, suggesting clinical trials are necessary.

A new study from a team of Brazilian scientists is reporting results from the first randomized, placebo-controlled clinical trial exploring the effect of cannabidiol (CBD) on anxiety, and anxiety-induced tremors, in Parkinson’s patients.

A new study has described the discovery of a previously unknown cannabinoid. Dubbed THCP, the molecule is significantly more potent that its well-known counterpart THC, however, it is unknown how present it is in common cannabis strains.

After months of concern, the CDC has revealed it's confident in claiming the “vast majority” of recent lung injury cases related to e-cigarette use can be linked to illicit THC vape liquids containing vitamin E acetate.

New research is presenting evidence that cannabis can significantly reduce the severity of headaches and migraines. But the question remains: why are scientists coming up with such discordant results on whether cannabis can reduce pain?

A new study has for the first time revealed one of the molecular mechanisms by which CBD directly blocks the negative psychiatric side effects generated by THC.
