Two men hurt, charged, in butane explosion in home involving hash.

The two men who were hurt in an explosion at a Longmont home on Wednesday were trying to make hash. Firefighters found a basement full of pot plants.

Police said three men were spraying butane into a jar of marijuana to make hash oil when it exploded.

One man suffered burns to his hands and face when butane vapors ignited in his garage which caused an explosion that blew out windows and brought neighbors running.

Police said the men were using butane to extract hash oil from marijuana. The oil is pure THC, the active ingredient in pot. It’s potent and explosive and sells for up to $100 a gram.

The men face charges of conspiracy and arson.

He said the owner of the home told investigators he moved to Longmont from New Jersey because of Colorado’s legalized pot laws. He was growing a large number of marijuana plants in his basement.

This is the third such explosion in Colorado in just over a year.
