Marijuana

A new study has identified a pattern of brain activity that seems to correlate with impairment from cannabis intoxication. The researchers suggest this novel brain-based biomarker could be a way to accurately measure THC impairment.

A study is outlining strategies that should be employed by cannabis growers to mitigate the plant’s ability to absorb heavy metals from soil. The study indicates it is possible cannabis contaminated with heavy metals could lead to chronic diseases.

A study has found epileptic children treated with whole plant cannabis products displayed reductions in seizure frequency. The researchers call for clinical trials to test whether whole plant products are better at treating epilepsy than CBD alone.

A new meta-study has concluded blood or saliva THC concentrations are not effective ways to measure cannabis-induced driving impairment. The findings indicate impairment tests should be developed instead of looking to develop a marijuana breathalyzer.

A study is offering one of the most comprehensive investigations ever conducted into the origins of cannabis' unique “skunk-like” smell, discovering an entirely new family of sulfur compounds that are chemically similar to compounds found in garlic.

New research systematically investigating the anticonvulsant effects of a number of rare compounds in cannabis is reporting cannabigerolic acid (CBGA), known as the “mother of all cannabinoids”, may be more effective at reducing seizures than CBD.

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.
