Should Native American Indians have to abide by the entirety of US law?

I don't think taking their land was that much of a big deal because they weren't doing that much with it and if they wished, they could revert to a traditional Indian lifestyle if they wished.

However, giving them reservations and Indian casinos seems a weak effort at placating them. Really I think they should morally/ethically be exempt from some parts of US law.

I'm not talking about murder or stuff like that. I mean drugs and victimless crimes like that. Indians (if they wish) should be able to get as high as they want and not worry about the law. IMO. What say ye?
