What is inside Cannabis?

Cannabis is a plant of over 1,000 chemical constituents, varying by chemotype (chemical phenotype), batch and crop. Cannabinoids are the most active compounds. There are over 150 discovered cannabinoids in the plant, including THC, CBD, CBN, and others. Over 230 Terpenes and Terpenoids (more commonly known as essential oils, e.g. pinene, limonene) give smell and taste to Cannabis and to all other plants in nature. Like cannabinoids, they also provide numerous medicinal qualities.

THC and CBD – Main Phytocannabinoids and Their Ratios:

THC (Tetrahydrocannabinol) provides many of the medicinal properties of Cannabis (see table below). THC is responsible for most of the psychoactive and neurological effects of Cannabis, including euphoria, laughter, altered sense of space and time, transient changes in short-term memory and coordination, heightened sensory perception (five senses). Finding an individual dose of THC that produces therapeutic benefits without affecting activities of daily living is the goal for most patients.


CBD (Cannabidiol) produces a multitude of medicinal effects of Cannabis and is considered a “non-psychoactive”, not mind-altering cannabinoid. CBD helps to decrease the psychoactivity and other side effects of THC (e.g. heart racing, hunger, anxiety, sedation) while enhancing some of THC’s benefits. At the 1:1 ratio of CBD to THC, psychoactive effects of THC start to diminish. At the ratio of 3:1 or more with CBD predominance, they are minimal to none.
