I am going to make this as simple as I can. So simple that even Reaganite red-state conservatives who follow Sean Hannity can get it.

The federal government classifies marijuana as a Schedule I controlled substance under the Controlled Substances Act (21 U.S.C. 801) with "a high potential for abuse," "no currently accepted medical use in treatment in the United States," and "a lack of accepted safety for use of the drug under medical supervision." Under federal law, possession of marijuana is punishable by a jail sentence not to exceed one year and a minimum fine of $1,000 for a first conviction, with increasing penalties for subsequent convictions. The Supreme Court has ruled that the federal government has the authority to prohibit marijuana possession and use for any and all purposes.

Most conservatives believe that this policy of the federal government is a good and necessary thing.

I have heard and read many conservative arguments over the years against the legalization of marijuana, for medical use or otherwise. Some of them are ridiculous. Some of them are just plain wrong. Some of them have an element of truth. Some of them contradict each other. Some of them might even be true.

I have listed these arguments here, or at least all that I could find or remember, all prefaced by "so what," which I will presently explain.
