|A damaged Colorado kitchen after a hash oil explosion|
It's called hash oil, and it's the production of it has led to numerous injuries and property damage, like one recent case in Lansing, Michigan which led to three men getting critically burned and a house destroyed.
Great. We already have meth labs causing explosions and toxic materials hazards and now we've got enterprising drug dealers with another explosive undertaking.
Another explosion at a hotel near Sea World in San Diego because of some moron making hash oil blowing the butane up when he lit a cigarette badly burned himself, injured at least one other guest and trashed a large portion of the hotel.
So innocent bystanders are under threat, too.
I'm not sure what can be done about all this, other than the standard law enforcement. But if you have sketchy neighbors, it looks like nasty explosions are one more thing you have to worry about.
