They ruled the same thing about wheat: http://en.wikipedia.org/wiki/Wickard_v._Filburn http://en.wikipedia.org/wiki/Wickard_v._Filburn It seems obvious to me that the authors of the interstate commerce clause didn't intend it to grant the authority to regulate anything and everything just because an interstate market for it exists, but the courts are generally quite hesitant to invalidate Federal laws. Practically speaking, most drug enforcement happens at the state level. This means that individual users and small sellers in states that legalized marijuana probably won't have many issues, but you won't see ABC Liquor and Cannabis opening its doors any time soon.
