New limits for homemade hash oil extraction head to Colorado governor

A ban on common procedures for making homemade hash oil is headed to the governor’s desk in Colorado.

The bill would make it a felony for amateurs to make hash or marijuana concentrate using an “inherently hazardous substance” such as a flammable liquid chemical or compressed gas. Such methods have been blamed for more than 30 butane explosions linked to hash production.

Just last week, an Eagle-Vail man was hospitalized after allegedly causing a fire while making a marijuana concentrate.

The city of Denver already bans flammable forms of home hash production. Under the bill, people would still be allowed to make homemade hash using less-flammable methods, such as soaking marijuana in a vegetable-based glycerin to extract the plant’s psychoactive material.
