Deputies and Investigators from the Teller County Sheriff's Office, along with officers from the Woodland Park Police Department raided a home near the city limits early Thursday morning. Nobody was home at the time, however, a large Butane Hash Oil (BHO) lab was discovered.

Investigators seized about 3 1/2 pounds of hash oil, which is a clear, golden-brown cannabis derivative also known as honey oil, shatter, wax or ear wax. BHO production in the home is not only illegal, but extremely dangerous.

According to a report by the Federal Emergency Management Administration (FEMA) in 2013, "Butane is necessary for the process and is available over-the-counter in 8-ounce cans. The extraction process uses one whole can and multiple cans will likely be at the scene. Butane is highly explosive, colorless, odorless and heavier than air and therefore can travel along the floor until it encounters an ignition source. The process also uses isopropyl or anhydrous alcohol, both flammable; extraction vessels; glass dishes; ether and coffee filters. The resulting substance is a thick yellow-orange oil called hash oil, honey oil, Butane Honey Oil (BHO) or dabs. Initial explosions can lead to secondary explosions and fires. In states with legalized use and availability of medical marijuana, these incidents appear to be increasing. In some of these states the legality of the actual production process is still in debate."

A person of interest is in custody in Iowa and there are two other people who are being sought for questioning in relation to this lab. The investigation continues.
