Me being a libertarian I'm against every federal legislation thet doesn't have something to do with national defense or foreign policy. So for me all these laws are clearly unconstitional at the federal level. But that doesn't mean the states couldn't take control of these matters. My personal belief is that any citizen of the US should be able to do what ever they want as long as it doesn't harm anyone else. Brewing your own booze and growing MJ clearly fall under this category. Nobody's goddamn business.
