CBD is the second most prominent compound in cannabis. The cannabis plant contains many different cannabinoids, we have seen over 80 different and it seems there are many more.
Most people have heard of a cannabinoid called THC, which is the ingredient in cannabis that gets users high. Unlike THC, CBD(cannabidiol) is non psychoactive cannabinoid and does not cause a high. CBD has antipsychotic effects which means CBD works completely the opposite way of THC. Numerous studies suggest that CBD also acts to reduce the intoxicating effects of THC.
The most common naturally occurring forms of CBD and THC are their acid forms, CBDa and THCa. Raw THCa is not psychoactive. It must be heated to form THC in order to become psychoactive.
