With more than 115 Americans dying every day from opioid overdoses, there’s no question that the current tools in place to help addicts aren’t working. Yasmin Hurd, PhD, and her team at Mount Sinai are changing that by investigating how using cannabinoids—chemicals extracted from marijuana that, unlike the better-known THC, do not get you high—can reduce cravings and ease withdrawal symptoms in heroin users. By studying molecular and neurochemical reactions in the brain, Dr. Hurd has found that cannabinoids have long-lasting therapeutic effects for heroin addicts.
