The Major Cannabinoids and Their Effects
The aroma of your cannabis and its effects are linked. Until recently, the effects of cannabis were thought to be caused exclusively by its cannabinoid (THC, CBD, etc.) content. Beginning in 2000, experts working with cannabis noticed the effects of different varieties of cannabis could not be explained just by cannabinoid content. Cannabinoids were interacting with another class of chemicals produced by the cannabis plant, called terpenes.
Terpenes are found in all aromatic plants and are responsible for their distinctive smells, from mint to citrus to grassy to fruity and woody aromas. Cannabinoids such as THC have no smell at all; they are odorless.
Terpenes have their own medicinal effects and modify the effects of cannabinoids. Terpenes are delicate molecules and quickly evaporate. To protect terpene content, always store medical cannabis in a cool and dark place.
