Metal, plastic, or glass tubes used to extract THC from marijuana can appear to be an improvised explosive device (IED). Further complicating recognition, is the then may be referred to as a “blaster”.
The extraction tube is used for “open blasting” where the tube is filled with marijuana and Butane is sprayed into the top of the tube through a small hole or valve. The THC/Butane mixture exit the bottom of the tube through a screen or cheese cloth.
