HELENA - Medical marijuana supporters are planning to collect signatures for a voter initiative that would block the strict regulations that Gov. Brian Schweitzer says he will allow become law this summer.

Meanwhile, advocates for outlawing medical pot altogether say they won't push for their own referendum after the Legislature passed a repeal of the state law, only to see it vetoed by Schweitzer.

After that veto, the Legislature passed a bill that aims to rein in Montana's booming pot industry and avoid federal intervention. It would significantly limit who can access the drug by doing away with pot businesses, implementing strict growing rules and setting new standards for patients and the doctors who certify them.

Schweitzer has said that he will allow the overhaul bill to become law without his signature, even though he criticized it for its ban on letting providers sell marijuana to patients. Schweitzer said this bill is better than letting the marijuana trade continue to grow.

Medical marijuana, passed by voter initiative in 2004, has been a huge growth industry since the Obama administration said in 2009 it would not prosecute patients who abide by state law. There are currently nearly 30,000 registered users in the multimillion dollar trade.
