Recreational marijuana sales began Saturday in Nevada, the fifth state to legalize recreational pot use despite continuing federal prohibition, with some dispensaries opening at midnight Saturday morning. The legalization was approved by ballot initiative in November with 55 percent public support.

Pot purchases are regulated much like alcohol, allowing buyers over 21 to purchase up to one ounce of marijuana at a time. However, it is still illegal to use recreational marijuana anywhere outside private residences, and it is also illegal to bring marijuana purchased in another state where it is legal, like Washington or Colorado, into Nevada.

Legalization is expected to be a major tourist draw for Las Vegas as well as a significant new source of state revenue.
