I do not possess the knowledge to claim that marijuana is a valid drug, but I am at least open to exploring the possibility. There is a significant association between substance use and violence. That alone is reason enough not to legalize drugs. The current movement to change the Marijuana laws focuses on the Medical use of the drug. A drug is placed and remains in a schedule based on administrative procedures.
Doctors have a great input into the classification of substances.
Marijuana has been the subject of numerous studies. The medical facts are that Marijuana has too many other compounds to make it safe. No legislature should be telling you what you can and cannot use to ease your pain if your doctor feels that it will assist you in living a pain free life. However, The American Medical Association, as well as, the several national associations such as multiple sclerosis, glaucoma, and ophthalmology has formally rejected it as treatment. See the Federal Register Volume 57, Number 59, dated March 26, 1992.
