Marijuana actually only serves a few medical purposes; some of which would be the treatment of glaucoma patients to reduce pressure in the eye and also the treatment of cancer patients to either give them an appetite or help ease the vomiting that comes with chemotherapy. As for aches and pains it may not do much other than give users an outlet to escape reality. There have been countless tests, experiments, and observations on marijuana being a gateway drug and all point to an undeliable yes. Most drugs have been illegal for a long time and our society has functioned perfectly without them so why make it legal now? There are plenty of other ways to make money other than the legalization of a drug. Also, the reprocussions of lealizing a harmful drug could cost the government more money than what it makes. I don't think America should be focusing on legalzing a drug that can break down the foundation that our nation was built upon, but instead focus on the much bigger issues facing our country today.
