In provisions regarding preliminary investigations where a drug overdose is determined to be the cause or a contributing factor in a death, modifies the definition of "overdose" to exclude death caused by fentanyl, which shall be considered poisoning. Provides that, in every case in which fentanyl is determined to be the cause or a contributing factor in the death, the coroner or medical examiner shall report the death to the Department of Public Health as "fentanyl poisoning".
