Pot, butane cans litter yard after hash oil explosion
PUYALLUP, Wash. -- Police say a hash oil extraction operation ended poorly for a group of Puyallup residents Tuesday night when a series of explosions destroyed their car and littered their yard with piles of marijuana and more than 300 cans of butane.

At least four people were trying to extract hash oil from marijuana outside of a home in the 1500 block of Shaw Road when the explosions occurred sometime before 9 p.m., according to Guy Overby of Central Pierce Fire and Rescue.

Hash oil is typically made by packing the castoff leaves and stems of pot plants into a pipe and pouring highly flammable butane through it. The concoction is heated to make the potent oil for far cheaper than it can be purchased in stores.

Without proper ventilation, butane fumes can linger. All it takes is a spark of static electricity to ignite a room.

Police and firefighters arrived on scene shortly after the blast and found a car on fire. Crews were able to extinguish the blaze in less than 15 minutes, Overby said. The home suffered minor fire damage.

"THC extraction process was going on here. It's fairly new to us, something we're still learning about, and they used basically butane gas to remove vegetation off of marijuana," said Sgt. Dan Pashon of the Puyallup Police Department.

Nobody was injured and police have detained two people. Officers are searching for two others thought to be part of the operation.

Overby said the lawn is littered with butane cans and pounds of marijuana.
