A House committee starts work Thursday on a proposal to make it a felony to use explosive gases to make hash oil at home.
The bill follows a rash of explosions and injuries resulting from amateur hash oil production.
Lawmakers in Washington state are mulling similar limits. The city of Denver already bans some types of home hash production.
In Colorado, at least 30 people were injured last year in 32 butane explosions involving hash oil. That's according to the Rocky Mountain High Intensity Drug Trafficking Area, a state-federal enforcement program.
