Communities could ban medical marijuana shops outright, and the ones that survive would have to reincarnate as nonprofit corporations subject to strict licensing and regulations under a bill unveiled by state lawmakers Wednesday, The Colorado Statesman reports. The long-anticipated bill by Rep. Tom Massey, R-Poncha Springs, and Sen. Chris Romer, D-Denver, would establish an 18-month moratorium on new marijuana businesses while allowing existing operations to transition over the same period into nonprofit “health centers” subject to rules modeled on the state’s liquor code. The bill was set to be introduced on Thursday and heard in the House Judiciary Committee on Monday.
