Update on a story we told you about earlier. A Wednesday explosion at a Queen Anne’s County cannabis facility leaves two people injured. WMAR reports the incident happened around 2pm at PharmaCann in Stevensville. Investigators believe the explosion occurred inside an extraction booth where propane and butane were being used. The gases are usually part of a process to extract THC and CBD from cannabis plants. Two employees were hurt, one of them severely, however both are expected to survive.
