That I'm not certain of. All I know is it's kind of a big issue here . . . with this being a red state, our officials, of course, assume making it legal will just result in everybody in the state turning into pot heads, so of course they're not going to go for that.
Which is ironic, because this is the same state that, a few years ago, made a big political issue out of . . . selling wine in grocery stores (which they did support, by the way).
