Denver city officials are moving to ban the amateur use of a risky hash oil extraction process that has resulted this year in dozens of home explosions statewide.

A new proposal backed by Mayor Michael Hancock’s administration would ban the home use of solvent-based hash oil extraction. It involves highly flammable compressed gasses, typically butane, in the extraction of oil from marijuana. An additional risk is that some users stock up on those gases in their homes.
