According to Dr. Mitch Earleywine, a University of Southern California psychologist who is the author of "Understanding Marijuana: A New Look at the Scientific Evidence" and the just published "Mind-Altering Drugs: The Science of Subjective Experience." The evidence is clear marijuana has no lethal dose, so you can't die from it. and so you can smoke all you want and not be knocked out like alcohol does. The impact on the brain structure for marijuana is nil, as compare to the very serious brain function changes from alcohol abuse. Also, more dramatic liver functions are impaired with alcohol. Malnutrition, B-vitamin deficiency, and Korsakoff's Disorder are all linked to alcohol, but not marijuana."
Its far safer to smoke a joint than to have a beer. It relieves the stress and tension after a hard days work or school. It mellows you out and helps you relax. It heightens the imagination and improves creativity. If you have a problem with anger, Pot is usually a good drug to reduce it. Marijuana has many medical benefits. It helps reduce problems with glaucoma. If you have cancer, it reduces nausea from chemotherapy. I had a friend who died of cancer. His doctor suggested Pot even though it wasn't legal. It allowed him to eat food again. This was three weeks before he died. I think the Pot gave him another week of quality life.
