The City of Sacramento hopes to restrict sales of butane with the goal of reducing the number of explosions in the city caused by people making "honey oil" or "hash oil" from marijuana.
Under proposed changes, sales of butane in the city would be limited to 600 milliliters per month per person.
"We're really trying to discourage and make it more difficult for people to do the home-extraction process of cannabis if you will," said Joe Devlin, head of the Office of Cannabis Policy and Enforcement. "It's very dangerous."
The changes would put the city in line with Sacramento County's ordinance.
Jared Brannan with the Sacramento Cannabis Manufacturing Association said he's in favor of the restrictions.
"I definitely agree with it being restricted and at this point, not being allowed for being an actual cannabis industry thing," Brannan said. "It is too early. There's not enough buildings or space."
The city allows for non-volatile extraction using carbon dioxide, but is considering allowing ethanol as well.
