Fire officials are investigating an explosion that occurred at a Petaluma home Monday night and may have been caused by butane gas that was being used to make marijuana "honey oil."
At 9:04 p.m., firefighters responded to a report of an explosion and possible fire at a home near La Cresta and Haven drives, according to officials.
When firefighters arrived at the home, they discovered evidence of an explosion, including damaged doors, sheetrock and windows as well as charred and melted materials inside, officials said.
Light smoke was coming from inside the house, but when fire crews entered, they exited due to safety concerns, according to officials who called police to the scene.
When officers arrived, they conducted a search of the residence and determined there were no threats to firefighters, fire officials said.
Once the house was cleared, firefighters entered and determined there was no active fire, according to fire officials.
Only one resident was home at the time of the explosion. He suffered minor injuries but was not taken to the hospital.

Police questioned the resident, however, he was not arrested. The investigation remains ongoing, according to Officer Rick Cox.
The cause for the explosion is under investigation but fire officials believe it is related to the marijuana "honey oil" production.
Damage is estimated to be worth $10,000, fire officials said.
