Dispensaries in Washington raked in over $1 billion in non-medical marijuana sales since the drug was legalized for recreational use back in 2012. The state allows people to carry up to one ounce of marijuana, but they must require the drug for medicinal purposes in order to be eligible for a grower's license.
Prior to the vote, it was legal to use recreational marijuana in only four states and in the District of Columbia. Colorado and Washington state voted to OK it in 2012. Alaska and Oregon voters approved it in 2014. For the states where recreational use is legal, it seems to have been a boost to the economy.
