THC, or tetrahydrocannabinol is the psychoactive cannabinoid in cannabis, which leads to that feeling of being “high” or “stoned”. In raw cannabis, THC comes in
its deactivated form of THC- A (tetrahydrocannabinol- acid); in order for it to become activated, it must be heated (or “lit”).
If you consume raw cannabis, you will not get “high” because the THC has not been activated. Health Canada warns that high THC content can increase the risk of psychosis and schizophrenia, with higher THC lowering the age of the onset of schizophrenia.
CBD, or cannabidiol is another cannabinoid found in cannabis. Unlike THC, CBD does not produce a high or feeling of intoxication. Preliminary research suggests that CBD can help block or lower some of the effects of THC. Research around the world is looking at evidence for the therapeutic uses of CBD.
