8.1. Cannabis metabolites

Cannabis plants represent a rich source of biologically active compounds, including more than 100 plant-derived cannabinoids (phytocannabinoids) and more than 200 terpenoids (Russo, 2011). Thus far, research into the medicinal effects of Cannabis has largely focussed on phytocannabinoids. Among these, the most well-studied are the psychoactive THC, and the non-psychoactive CBD, though other phytocannabinoids such as CBG and CBC also show therapeutic potential (Russo, 2011) (see also chapter 3 for details on phytocannabinoid synthesis and genetics).
