A panel of state senators voted Tuesday to scrap most of the administration's plans to change Colorado's rules regulating how medical marijuana is grown and sold.
The vote came in a hearing called to renew the state's 2010 pot regulations, which expire this year if lawmakers don't act.
Gov. John Hickenlooper's regulators wanted 15 changes, including a crackdown on caregivers, who are the people authorized to grow pot on behalf of people on the medical marijuana registry.
But senators from both parties voted 5-0 not to take that approach. Instead, lawmakers will debate every aspect of the medical marijuana code, opening the door for big changes to how the drug is grown and sold.
