Use of cannabinoid drugs to combat osteoporosis and other bone-related diseases may come into play in the near future. A component in marijuana can significantly help heal bone fractures, according to a new study.
According to the research at Tel Aviv University and Hebrew University, the administration of the non-psychotropic component cannabinoid cannabidiol (CBD) helps heal bone fractures.
AdvertisementThe study was conducted on rats with mid-femoral fractures. It was found that CBD - even when isolated from tetrahydrocannabinol (THC), the major psychoactive component of cannabis - markedly enhanced the healing process of the femora after just eight weeks.
"The clinical potential of cannabinoid-related compounds is simply undeniable at this point," said Dr Yankel Gabet of the Bone Research Laboratory at the Department of Anatomy at Tel Aviv University.
The same team, in earlier research, discovered that cannabinoid receptors within our bodies stimulated bone formation and inhibited bone loss. "While there is still a lot of work to be done to develop appropriate therapies, it is clear that it is possible to detach a clinical therapy objective from the psycho activity of cannabis. CBD, the principal agent in our study, is primarily anti-inflammatory and has no psycho activity," said Gabet.
According to Gabet, our bodies are equipped with a cannabinoid system, which regulates both vital and non-vital systems. "We only respond to cannabis because we are built with intrinsic compounds and receptors that can also be activated by compounds in the cannabis plant," he said.
Researchers found that the skeleton itself is regulated by cannabinoids. Even the addition of a non-psychogenic compound acting outside of the brain can affect the skeleton.
"We found that CBD alone makes bones stronger during healing, enhancing the maturation of the collagenous matrix, which provides the basis for new mineralisation of bone tissue," said Gabet.
The researchers injected one group of rats with CBD alone and another with a combination of CBD and THC. After evaluating the administration of THC and CBD together in the rats, they found CBD alone provided the necessary therapeutic stimulus.
"We found CBD alone to be sufficiently effective in enhancing fracture healing," said Gabet. "Other studies have also shown CBD to be a safe agent, which leads us to believe we should continue this line of study in clinical trials to assess its usefulness in improving human fracture healing," Gabet added.
