Apparently the marijuana users did argue that there was no interstate commerce involved in the case discussed [here][4].1 They grew their own. Thus there was no commerce at all here. However, under an unnamed Supreme Court ruling 63 years ago (I really need to learn when the Warren court was, but if I did, I would just forget it, I am bad with dates), the commerce power extends beyond the true interstate commerce because "the cumulative effect of even minor and local economic activities can have interstate consequences."2 While I understand the logic here, I am not sure that I agree with its necessity, and I am fairly certain that I dislike its consequences. It certainly moves the current decision from being questionable to being certain. All told, I think Justice Thomas' words sum things up well: "If Congress can regulate this under the Commerce Clause, then it can regulate virtually anything" thus "the federal government is no longer one of limited and enumerated powers."3
