AUGUSTA – More than a year after Maine voters legalized the limited medical use of marijuana, a new proposal would establish a pilot program to distribute marijuana to Mainers who need it for medical reasons.

The bill, which still is being drafted, would create a nonprofit center to grow and distribute marijuana within a test county. A registry system would ensure that marijuana is sold only to those who are legally entitled to it.

Under existing law, Mainers with problems stemming from cancer, chemotherapy, AIDS or other specified conditions may possess six marijuana plants and 11/4 ounces of dried marijuana.

Supporters of the new measure say it would help Mainers who are too sick or too poor to grow their own marijuana, and those who can’t or won’t buy it illegally.

“If it was done properly, everyone would benefit from it,” said Cliff Hall, who suffers from a spinal-cord injury and uses marijuana to relieve painful muscle spasms.

“It would take the stigma away from me having to go to the black market,” while ensuring that the quality is consistent from batch to batch, said Hall, who has a doctor’s written recommendation that he use marijuana.

Hall, who has grown his own marijuana, said state-sanctioned distribution is “a very necessary part of what the public approved in the referendum.”

In a report released last October, most of the 29 members of a task force exploring ways to improve the medical marijuana law endorsed state-sanctioned distribution. Many also supported creating a research program on the medical benefits of marijuana and allowing each legal user to grow enough for one other registered patient.

So far, at least, the only one of those ideas that has surfaced in the Legislature is the pilot distribution plan.

An early draft of the bill says the distribution center could grow marijuana and charge patients enough to cover costs. The center would have to work with the sheriff in the center’s home county to set up and maintain a registry of eligible patients.

The bill does not specify which county would get the center. Eventually, the center would have to submit a report to the Legislature, which then would decide whether to expand the idea to other counties.

“We really haven’t provided a way to [distribute marijuana] that is legal,” so the Legislature should tackle the problem with a test program in one county, said Sen. Anne Rand, D-Portland, a sponsor of the bill.

“The referendum was a good step,” said Elizabeth Beane of Mainers for Medical Rights, which promoted the referendum and supports the new law. “Growing your own seemed like the way to go” at the time, Beane said, but it has become clear since then that home growing is not practical for all patients who are entitled to the drug.

Opposition to state-approved distribution is sure to surface in the Legislature.

“Clearly, it presents tremendous issues,” said Roy McKinney, director of the Maine Drug Enforcement Agency and one of the dissenters on the task force.

The federal government still views marijuana as a narcotic that is easily abused and that has no medical benefits, McKinney said, so “the issue of conflict with federal law” would pose problems if the state sanctioned a distribution system.
