Cannabis sativa is the most common type of cannabis plant, although there are other forms of cannabis including Cannabis indica and Cannabis ruderalis. Of over 480 different compounds present in the plant, only around 66 are termed cannabinoids. The most well known among these compounds is the delta-9-tetrahydrocannabinol (Δ9-THC), which is the main psychoactive ingredient in cannabis. In Switzerland no strain can surpass 0% THC for cosmetics. Cannabidiol (CBD) is another important component, which makes up about 40% of the plant resin extract.
