Another marijuana post

I know people have been doing a lot legalization of marijuana rants but i want to look at it from a philosophical perspective. In a traditional natural law theorist's point of view, if you believe marijuana to be immoral than it should be illegal. However, natural law also says to do what makes your life better and more enjoyable to you. If you find nothing wrong with marijuana use, then it should be perfectly legal. In a positivist approach, if the law says its illegal, then in no way, shape, or form should be allowed. Both medical and recreational use should be made illegal. A realist approach, which i agree with, says the courts and judges should take a look at each case individually. State laws on medical use of marijuana are very strict. Dispensaries have to jump through many hoops to stay in business. How can a judge or jury look at an individual suffering from MS and sentence them to prison for taking medication that relieves their everyday pain? Now, if a nationwide drug dealer who is responsible for bringing in hundreds of pounds into residential neighbors is standing trial, then yes they should be sentenced accordingly. I'm not exactly sure how feminism fits into this scheme of things but as long as males and females are being treated the same by the law, i do not see them having a problem. Law and economics theorists would be all for the legalization of medical marijuana because, after the state applies very taxes to its sale, the governments will make a very large profit.
