Science Says Marijuana Helps Heal Broken Bones Mansa MusaJuly 22, 2015Live N LearnPositive Vibes Science Says Marijuana Helps Heal Broken Bones A new study takes a look at how marijuana may help heal broken bones. Researchers at Tel Aviv University and Hebrew University found that CBD, a non-psychotropic component of marijuana, strengthened fractured bones during their healing process. CBD, or cannabinoid cannabidiol, doesn’t make you feel high—it’s different from THC, the major psychoactive component in marijuana. Researchers found that when they gave a group of lab rats with leg fractures CBD, their bones were noticeably stronger after eight weeks. Researchers also tested what happened when they gave the rats a mixture of CBD and THC, but found that “CBD alone” was useful as therapy.
