01 Aug 2019 --- Exposure to delta-9-tetrahydrocannabinol (THC), the principal psychoactive cannabinoid found in cannabis, can induce inflammation and oxidative stress, which are known to affect the inner linings of blood vessels and are associated with the development of heart disease, according to research by the American Heart Association. The study also found that in laboratory tests, a compound found in soybeans blocked damage to the lining of blood vessels in the heart and circulatory system. The researchers point to these findings as an avenue to prevent the cardiovascular side effects of recreational and medical marijuana use.
