A fire that scorched a man's legs Monday and caused thousands of dollars worth of damage to his home's kitchen started during an operation intended to extract oil from cannabis.

Medford Fire-Rescue responded to the incident at 11:09 a.m., according to dispatch logs, in the 3000 block of Alley Lane, off Highway 99 between Phoenix and Medford.

Fire Inspector Tanner Fairrington said a man in his 30s was using alcohol to extract marijuana oil from pot plants. The product is called Rick Simpson Oil, which is different than the honey oil extracted using butane, said Fairrington, who noted the process is legal but should not be done in an enclosed space.

The fire sparked when a crock pot was plugged in. The man suffered burns on his legs, and the fire damaged multiple cabinets and part of the ceiling in the kitchen. Two engines and a brush rig responded to the scene.
