e the hippocampus, relevant to altered levels of cognition, and the cortex and the cerebellum, relevant to interruption of normal motor function and coordination. (4) The Immune system is weakened according to a accumulating body of research data indicates that marijuana and some of its components influence the immune system and affect the body’s ability to resist microbes, including viruses, bacteria, fungi, and protozoa, and decreases the body’s antitumor activities. These effects are compounded because marijuana use has occurred concurrently with the increased spread of sexually transmitted diseases like type B viral hepatitis, genital herpes, and AIDS. Because these diseases also target the immune system, marijuana users who are already vulnerable to infection may be especially compromised in their body’s ability to fight infection. The Endocrine system includes organs and glands that produce hormones and is effected according to “several studies, animal and human, conclude that chronic and acute use of marijuana alters the secretion of hormones from the endocrine system, which may have an effect on the reproductive system and the individual’s ability to respond to different metabolic changes and stress”.

Although marijuana may work as an antiemetic or as a way to reduce ocular pressure in glaucoma, problems caused by THC on the immune system or the pulmonary system or other systems may outweigh any positive effects. For many of the other medical applications listed above, there are very few or weak scientific data about efficacy, or there are many other e...
