DENVER (AP) — The opening months of Colorado's first-in-the-nation recreational marijuana industry have seen a rise in fiery explosions and injuries as pot users try to make the drug's intoxicating oil in crude home-based laboratories.
Since Jan. 1, when sales began, the state's only certified adult burn center has treated 10 people with serious injuries they suffered while making hash oil, compared with 11 in 2013 and one in 2012.
Law enforcement and fire officials, meanwhile, are grappling with how to respond, as the questionable legality of the process has made it difficult to punish amateur chemists. Some prosecutors are charging them with felonies, while others say hash oil production is protected under a provision of the new legal pot law.
"These today are the meth labs of the '90s. We have to change our thinking and what we're looking for," said police Sgt. Pat Long in Thornton, a Denver suburb where officers were puzzled by the city's first hash oil explosion in January.
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.
The golden mixture can be up to 80 percent THC, marijuana's intoxicating chemical, and devotees say one or two drops can produce a more euphoric high than an entire joint. It can also be infused into baked goods or vaporized.
Without proper ventilation, butane fumes can linger. All it takes is a spark of static electricity to ignite a room.
Firefighters in the state have raced to at least 31 butane hash oil explosions this year, compared with 11 last year, according to the Rocky Mountain High Intensity Drug Trafficking Area, an agency that has only recently started tallying cases.
The data represents only reported and confirmed cases, and the actual number of explosions could be higher, said Kevin Wong, an intelligence analyst for the agency. "This is just the tip of the iceberg," Wong said.
The organization has started training police and firefighters on how to spot the signs of a hash oil explosion. After the Thornton blast, officers found a charred home littered with bottles of butane. They were perplexed, which highlighted the need for more training, Long said.
In recent years, there have been dozens of explosions and injuries in other states where residents can get access to the plant through medical marijuana systems, including California, Washington state and Oregon.
