DENVER - Rocky Mountain High took on a new meaning Tuesday night as Colorado voters approved legalizing marijuana.
Colorado's amendment allows adults to possess up to 1 ounce of the drug, or six plants. It also directs lawmakers to tax pot up to 15 percent, potentially generating millions for the state.
When state and federal laws conflict, federal law takes precedence. Federal authorities could sue in an attempt to block Amendment 64 from taking effect.
Legalization backers argued that marijuana is no more dangerous than alcohol and should be regulated and taxed. Opponents said legalizing pot would increase its use and make it easier for youths to obtain it.
A measure to legalize marijuana also passed in Washington State but a similar measure failed in Oregon.
The measures will set up a direct challenge to federal drug law.
