Portland Marijuana Referendum Backers Unveil Ads 

PORTLAND, Maine (AP) — Supporters of a Portland referendum seeking to legalize recreational marijuana possession are launching a Maine ad campaign.

The Marijuana Policy Project is unveiling ads Wednesday that will appear on public transit buses and bus shelters. The campaign features six ads, each with a photo of an adult explaining why he or she prefers marijuana over alcohol and asking why they should punished for making the choice.

Portland residents will vote in November on whether if it should be legal for adults 21 and older to possess up to 2 1/2 ounces of pot. The law would prohibit using marijuana in public, and would not legalize its sale.

Referendum supporters turned in more than 2,500 valid signatures to Portland city officials in May to get the question on the ballot.
