what states have been legalized for marijiuana?
Drewdad's answer is correct: technically, none. Federal law always trumps state statutes and there is a federal law against marijuana. California, Hawaii and any number of other states can all remove state laws against marijuana and approve it for medicinal or recreational use, and the DEA (Drug Enformcement Administration) can still come and arrest you. Now, the fact is that they don't do that. The DEA and other Federal agencies are not interested in busting small-time users; they have much bigger fish they wish to fry -- the dealers and suppliers. But, in fact, you're never totally safe in the use of a federally outlawed substance.
