Delta 9 THC – Delta-9 THC, or what is commonly referred to as THC, is the main psychoactive compound of the cannabis plant. Found in both male and female cannabis plants, the concentration is much higher in female plants. It is interesting to note that while THC is in its raw form (THCA), it has no mind-altering properties. This only happens as decarboxylation occurs and heat alters the original molecule into one that can bind with the cannabinoid receptors in our body, located in the endocannabinoid system, to produce that euphoric feeling known as a “high.”
