A small human pilot study, along with a number of animal studies, are revealing that cannabinoids, extracts of cannabis legally sold as medical marijuana, could reduce cravings and ease withdrawal symptoms in heroin users. In light of the U.S. opioid epidemic, this is a neglected area of research that quickly needs attention, argues neurobiologist Yasmin Hurd of the Icahn School of Medicine at Mount Sinai, who studies how both cannabinoids and opioids act on the brain. She discusses her position in a short review published February 2 in Trends in Neurosciences.
