Voters in Oregon, Alaska and Washington, D.C. voted to legalize the recreational use of marijuana on Tuesday.

The pro-pot legislation passed in the three states on Election Day. Once it goes into effect, adults over 21 years old in Oregon will be allowed to possess, manufacture and sell marijuana. Likewise, under Alaska's law, the sale and use of cannabis will be taxed and regulated.

However, D.C.'s proposal only permits a person over 21 years old to possess up to two ounces of marijuana for personal use and grow up to six cannabis plants within their home. Although people will be restricted from selling pot, they will be allowed to transfer up to one ounce of marijuana to another person.

Oregon and Alaska are expected to usher in a network of retail pot shops similar to those currently operating in Washington State and Colorado, which became the first two states to approve sweeping marijuana bills in 2012.

Florida voters, however, rejected the use of medical marijuana in the state.

"It's always an uphill battle to win a marijuana legalization initiative in a year like this, when young people are so much less likely to vote, which makes today's victory all the sweeter," said Ethan Nadelmann, the executive director of the Drug Policy Alliance, referring to the referendum in, according to CNN. "The pace of reform is accelerating, other states are sure to follow, and even Congress is poised to wake from its slumber."

However, there is a chance that the Republican controlled Congress may overrule the law in D.C.

Moving forward, marijuana advocates are looking to add ballot initiatives to legal marijuana in states like California, Massachusetts, Maine, Nevada and Arizona in 2016.

"In 2016 we're going to push the ball forward in several states until we end prohibition," Leland Berger, a Portland attorney who helped write the new law, told Reuters outside a packed Portland nightclub where advocates declared victory amid pot-centric revelry.
