An effort to overhaul Montana’s medical marijuana law, introduced in the Senate this week, is vastly different than Montana’s current law. House bill 423 tries to limit the amount of medical marijuana available throughout the State, and who has access to the drug. It would put much tighter regulations on how patients can receive the drug, on who can grow it, and how it is sold and distributed. Senate Majority Leader Jeff Essman described the new proposal as having three phases. The first phase is a repeal of the current law. The second is to cleanse the state of the old industry, and the third phase would then tighten regulation of the new system.
