On Tuesday, Alaska became the first red state to legalize the smoking, growing, and owning of small amounts of marijuana, bringing the decriminalization movement to a conservative stronghold.

The frontier state narrowly approved the measure last fall, by 53 percent, joining Colorado and Washington states in legalizing recreational use.

Under the law,adults 21 and older may possess up to anounce of potandgrow as many as six plants. But smoking in public and buying and selling the drug remains illegal, which makes it difficult to (legally) acquire.

"You can still give people marijuana, but you can't buy it or even barter for it," Alaska Public Media's Alexandra Gutierrez reports. "So, it's a pretty legally awkward spot. That probably won't stop people from acquiring it, though."

Alaska is the third state to legalize recreational marijuana after Colorado and Washington. Oregon and Washington, DC, are expected to follow later this year. But Alaska is unique in that it is the first solidly red state to legalize the drug.

Why did a conservative state take a decidedly liberal position on marijuana?

Although it is a Republican stronghold, Alaskans are known for their rugged individualism and libertarianism.

"This is a conservative state, but it's a state with a heavy libertarian streak," Bickford said. "People here generally want to be left alone and really don't think the government is the solution to their problems," Taylor Bickford, a spokesperson for the Campaign to Regulate Marijuana Like Alcohol in Alaska, told Vox News.

And it turns out Alaska has always been on the forefront of pot legalization. It was one of the first states to decriminalize marijuana in 1975, and voters in 1998 legalized the drug for medicinal purposes, according to the site.

This time, an unlikely coalition of libertarians, individualists and small-government minded Republicans helped legalize recreational marijuana last fall.
