The process of using butane to extract THC from marijuana and create a highly concentrated and potent form of the drug has grown, particularly in states that have legalized marijuana. It has been accompanied by explosions and house fires related to the extraction process.
An 85-year-old woman died in early December, two weeks after a Nov. 22 explosion and house fire at 1919 First St. N.
Sally Douglas was injured from smoke inhalation and died at Hennepin County Medical Center two weeks after the fire.
