Cannabis sativa is a plant commonly known as marijuana. It has been considered a stimulant drug since it causes some drug effects when inhaled or ingested. Marijuana has also been widely used in medical research and development of medicine.

The term medical marijuana is used to describe unprocessed marijuana plants and extracts used in the treatment of symptoms and diseases. Cannabinoids are extracts from marijuana that have been used in scientific studies and manufactured into approved medications.

Legal vs. Illegal

The fight for the legalization of marijuana in many countries has been widely supported by research and studies that show that marijuana contains extracts that can treat and manage various symptoms and conditions.

Marijuana has been legalized for medical use in many states and countries. However, it is still a controlled substance and there are some areas where one may be charged for possessing certain amounts of the plant illegally

Why is marijuana itself not an approved medicine

In order for any product to be approved as medicine, it needs a lot of studies and clinical trials on human subjects in order to come up with clear benefits and risks of using the product.

However, the use of marijuana is experimental among most subjects and the results can be considered speculative since only some cases have been known to benefit from using the plant. Large-scale clinical trials have not been conducted to show the specific benefits and risks of using the plant.


Although there are more than 100 other cannabinoids in the marijuana plant, THC Cannabinoids are the main component in the plant that has mind-altering effects. Extremely powerful cannabinoids illegally manufactured by some scientists have led to serious health problems with continued abuse.

Cannabinoids produced by the body help in regulation of blood pressure, concentration, body movements, pain, appetite, senses and thinking and this is why the controlled used of medical marijuana has some benefits to patients.
