Ballot measures to legalize casual marijuana use were leading in Washington state and Colorado on Tuesday night, but a similar measure lost in Oregon.
Washington's Initiative Measure No. 202 held a 55%-45% lead, according to the Washington secretary of state. That did not include mail-in ballots, which need not be postmarked until election day.
In Colorado, the secretary of state was still tallying votes, but the Denver Post projected that Amendment 64 would be successful.
Both measures call for marijuana to be legalized and regulated similar to alcohol.
Marijuana advocates claimed double victories.
“The significance of these events cannot be understated,” Erik Altieri, a spokesman for the marijuana advocacy group NORML, said in a statement. “Tonight, for the first time in history, two states have legalized and regulated the adult use and sale of cannabis. We now must focus on the important work of implementation and begin to encourage other states to adopt these rational reforms.”
