Doug Fir

Prūf No. 42

Every cannabis strain possesses a unique ratio of THC to CBD. THC (tetrahydrocannabinol) is the psychoactive component of cannabis. CBD (cannabidiol) is a therapeutic compound showing promise at relieving pain and anxiety. A Type 1 plant, with high THC and low CBD, is more intoxicating than a plant than a mixed ratio Type 2, or a Type 3 high CBD/low THC plant.
