Which US state legalized recreational marijuana in 2015?

The US state that legalized recreational marijuana in 2015 is Oregon. In November 2014, Oregon voters approved Measure 91, which legalized recreational marijuana for adults aged 21 and over, and allowed people to possess up to eight ounces of marijuana in their homes and up to one ounce of marijuana outside their homes. Measure 91 also allowed individuals to grow up to four marijuana plants per household.

With the legalization of recreational marijuana, Oregon joined Colorado, Washington, and Alaska in allowing adults to use marijuana in a recreational context. However, Oregon's approach to legalization has been more permissive than the other states that have legalized recreational marijuana, with fewer restrictions on where the drug can be consumed and a lower tax rate.

It's important to note that while marijuana is legal for recreational use in some US states, it's still illegal under federal law. This has created a number of challenges for states that have legalized marijuana, including difficulties in accessing banking services and concerns about federal enforcement of drug laws.

No US state legalized recreational marijuana in 2015. The first two US states to legalize recreational marijuana were Colorado and Washington, in 2014. However, in 2015, the Flandreau Santee Sioux Tribe (South Dakota) voted to legalize recreational cannabis on its reservation. The Squaxin Island Tribe in the Puget Sound area also legalized and opened the United States' first tribal retail cannabis sales shop on their trust lands.
