When talking about the chemical compounds found in cannabis, perhaps no cannabinoid looms quite as large as tetrahydrocannabinol, or THC. THC is by far the most abundant cannabinoid found in most modern cannabis strains, whether they’re classified as indica, sativa or as a hybrid of the two. As female cannabis plants grow and bloom, their flowers produce structures known as trichomes (see picture below). Trichomes are the site where cannabis plants produce most of their cannabinoid content, as well as their terpenes.

Unlike the second-most abundant cannabinoid in cannabis, cannabidiol, or CBD, THC does not hold the same benevolent reputation in much of the public mind for medical benefit potential. In fact, for many, THC is perhaps most associated strictly with its psychoactive effects, producing the “high” so often associated with the recreational use of cannabis. Nevertheless, the international scientific community is in fact carrying out research into the potential therapeutic effects of THC. Listed below are links to ongoing, peer-reviewed scientific research into THC.
