Medical professionals warn of the dangers of sharing prescription drugs, which can lead to accidental overdoses and poisonings.

According to the Drug Enforcement Administration, which hosts the take-back events, disposing of prescriptions by tossing them down the toilet or dumping them in the trash can also pose health and safety hazards.

— Kaiser Permanente Hospital, parking lot, 10800 Magnolia Ave., Riverside;
