Scientists have found a way to separate the medical benefits of cannabis from its negative effects. A new marijuana study has identified the pathway used by cannabis’ main psychoactive ingredient, tetrahydrocannabinol (THC).
The study published in the PLOS Biology journal Thursday stated how the cognitive effects of THC such as memory loss and anxiety are caused by a pathway, which is different from its beneficial effects such as pain relief. The findings showed that the pathway involved cannabinoid and serotonin receptors.
Researchers at the University of East Anglia, Norwich, England, along with the Pompeu Fabra University in Barcelona, Spain, conducted the study on mice. When they blocked the pathway in mice, the THC still showed medical benefits like pain relief and reduced nausea, the researchers said in a statement. The study team noted that it also decreased the chances of memory impairment, which is a common side effect of cannabis.
