Communities across British Columbia are conducting safety inspections of suspected marihuana grow operations and clandestine drug labs to address the health and safety hazards associated with these sites, including fire, unsafe structural alterations, illegal and unsafe wiring, mould and chemical spills. Marihuana grow operations are 24 times more likely to catch fire than a typical home. Medical marihuana grow operations are equally at risk from these hazards, due to a lack of oversight and disclosure of the sites to local authorities.
