Marijuana contains more than three hundred compounds. At least seventy of these are cannabinoids, which are the basis for medical utilization of cannabis. Five important cannabinoids found in the cannabis are tetrahydrocannabinol, cannabidiol, cannabinol, cannabigerol and beta-caryophillene but two of these ones are mainly used in medicine;


The first one is the tetrahydrocannabinol (THC), which is the main compound responsible for the psychoactive effects of cannabis. This compound is an analgesic, and some researches have shown that it also had an antioxidant activity. THC is believed to interfere with parts of the brain normally controlled by the endogenous cannabinoid neurotransmitter called anandamide. Anandamide plays a role in pain sensation, memory and sleep.

The second one is the cannabidiol (CBD), which represents more than 40% of extracts of the medical cannabis plant. Cannabidiol is known to relieve inflammation, convulsion, anxiety, nausea, and inhibits cancer cell growth. CBD is also very effective in the treatment of multiple sclerosis, Tourette syndrome and schizophrenia because it acts as an anti psychotic.

Preliminary findings have shown that cannabis or cannabinoids were very useful in the treatment of nausea, insomnia, premenstrual syndrome, arthritis, cancer, depression, epilepsy and anorexia nervosa.


Other effects have been observed in the treatment of painful conditions like neurologic pain, movement disorders (ex: parkinson's disease), asthma, glaucoma, migraines, fibromyalgia (muscular pain) and inflammatory bowel disease (ex: stomach ulcer).
