Problem drug use (PDU) is defined as recurrent drug use that is causing harm to an individual, or is placing them at a high probability or risk of suffering harm.1 Substances associated with PDU include opioids, cocaine (powder and crack), amphetamines, benzodiazepines, Z-drugs, and gabapentinoids. PDU can lead to many harms for populations and individuals. Such harms include increased criminal activity, drug-related litter, increased risk of infectious diseases passed on from shared syringes and needles, substance use disorders, overdoses, and death.
