Finally in 1964, Professor Raphael Mechoulam and his colleague, Yechiel Gaoni, at the Weizman Institute of Science in Israel, isolated, analyzed and synthesized the main psychoactive ingredient in the cannabis plant as tetrahydrocannabinol, or THC. Professor Mechoulam, now 84, stated in an interview that he has been urging producers over the years to grow cannabis with less THC and more CBD. (Nonmedical marijuana growers have little interest because CBD has NO psychoactive properties.) Taking Professor Mechoulam’s advice, a government approved medical marijuana farm, Tikkun Olam, began working on a high CBD and low to no THC strain of cannabis. After years of careful breeding, they developed, Avidekel, a strain rich in CBD but with little to no THC. This break through has allowed tens of thousands of Israelis to enjoy the health benefits of CBD.
