In some states, marijuana is illegal. In others, it's legal for medical purposes. And still in others, it is even legal for recreational use.
Recreational pot has been legal in Oregon now for a year, but it was a long time coming. Voters approved medicinal pot 20 years ago. Arizona is voting on it this fall – along with California, Nevada, Maine and Massachusetts. It was only six years ago that Arizona approved marijuana for medicinal use.
