An Arizona citizens’ initiative campaign to legalize marijuana announced today that it has reached 200,000 signatures — more than needed to make November’s ballot.

But the campaign is shooting for far more than it needs — at least 225,000 signatures — in case some are invalidated.

“Voters want to have their say on whether Arizona should end marijuana prohibition,” said J.P. Holyoak, chairman of the Campaign to Regulate Marijuana Like Alcohol. “It’s appearing more and more likely that they are going to have that opportunity. We’re finding that most Arizonans agree marijuana should be regulated and taxed similarly to alcohol.”

Under the initiative, adults 21 and older would be allowed to be possess up to an ounce of marijuana with no legal penalty, and between an ounce and 2.5 ounces would be a civil offense with a $300 fine. Marijuana would be sold through a system of retail stores governed by a new state agency, the Department of Marijuana Licensing and Control. Adults could also grow up to six plants in their homes, subject to consent of property owners and potential municipal restrictions on “nuisances.”  [Read more at Phoenix New Times]
