Today, there are thousands of varieties of cannabis with different cannabinoid profiles, including THC (tetrahydrocannabinol). These varieties are known as cannabis genetics or strains. The exact number of THC genetics available on the market is difficult to determine, as there is constant cross-breeding and creation of new strains. However, some popular and widely recognised THC genetics can be identified.

These are just some of the most popular THC genetics, but the diversity of cannabis allows for a wide range of variations in cannabinoid profiles and effects. Each genetic has unique characteristics that can offer different experiences and therapeutic benefits. It is important to note that availability and strains may vary depending on the location and legal regulations of each country or state.
