With prescription drug abuse one of the top killers among teens, the Santa Cruz Police Department has a place to get rid of those you don't want anymore.
From their blog:
The Santa Cruz Police Department would like to remind the community about our on-going prescription drug take-back program. This program, offered by the Santa Cruz Police Department, provides a no-cost, anonymous collection point for unwanted or expired medicines. We have a secure, self-service collection bin in our public lobby that is available to community members Monday through Thursday from 9:00 a.m. until 4:00 p.m. Simply bring your unwanted or expired medicines to the police department during the hours that our public lobby is open and use the self-service bin which is clearly marked and located in the left-hand corner of the front lobby as you face the front counter.
