Voters approved a referendum making Maine the fifth state to allow retail pot dispensaries, but medical marijuana advocates say it won't become like California, where hundreds of marijuana shops have popped up and come under critical scrutiny.

California, Colorado, New Mexico and Rhode Island allow for places where medical marijuana patients can legally buy pot. Maine voters gave their approval Tuesday, 59 percent to 41 percent.

Referendum opponents pointed at Los Angeles as proof that cannabis outlets are a bad idea. There, the district attorney has vowed to crack down on places that are selling the drug to people who don't qualify.

But Ethan Nadelmann of the New York-based Drug Policy Alliance said there's no chance Maine would become like Los Angeles, which he called the "wild west West" of medical marijuana, because of stricter provisions.

Maine law requires that dispensaries be licensed by the state, while California law does not, he said. Maine law also narrowly defines medical conditions for which patients can be prescribed pot, while California allows doctors to recommend it for virtually any ailment.

"You aren't going to see hundreds of dispensaries popping up all over Maine," Nadelmann said. "You're going to see a more regulated system."

Nonetheless, the director of the Maine Drug Enforcement Agency said the language of the Maine referendum lacks proper oversight and control. The potential exists for a dispensary to become "nothing more than a storefront for the criminal activity of drug dealing, which is the experience in California," said Roy McKinney.

"If there isn't sufficient oversight, inspection, audits, etc., the potential is there for criminal activity to flourish," he said.

Fourteen states have laws allowing some use of marijuana for medical purposes. Maine's medical marijuana law, first approved in 1999, allows the use of pot for debilitating conditions such as cancer, AIDS and multiple sclerosis.

The original law allows patients to possess up to 2 1/2 ounces of pot and up to six marijuana plants, but many of those patients don't have a legal way to obtain it. The new law will give them places where they can buy it. Continued...
