A fire that burned a downtown Eugene building was allegedly caused by an enthusiast of marijuana making hash oil. It is illegal to use butane to extract cannabis. It is legal if the person has a license from the OLCC as a recreational processor. They also have to be licensed by OHA specifically as a medical processor with the state.
“Over the years, there have been many hash oil incidents that have led to serious injuries. In 2017, Eric Scully was sentenced to seven years in prison for setting a storage facility on fire when he was making butane hash oil.” (Dendy, 2020)
