California has industry-run statewide stewardship programs that provide safe and convenient disposal options for pharmaceutical and home-generated sharps waste at no cost to the consumer.
How to Safely Dispose of Unwanted Household Medications
Don’t flush your drugs! Flushing unwanted and expired medications down the toilet is the least desirable of all disposal alternatives. Wastewater treatment facilities are not equipped to remove all traces of pharmaceutical chemicals. If you flush your drugs, a portion of those contaminants will reach local waters. Scientific studies show the chemicals in many drugs can harm aquatic life. Proper disposal of unwanted medications helps protect your family, your community and the environment.
The best way to dispose of your unwanted or expired household medicine and/or prescription drugs is at a hazardous waste facility, drop-off or take-back program.
West Contra Costa residents may drop-off unwanted or expired medicine for free at the below listed locations.

How to Safely Dispose of Unwanted Needles & Sharps
Why You Should Be Careful with Sharps
Improper disposal of used or unwanted “sharps” (needles, syringes, lancets and other sharps items) can cause a serious injury and pose health risks to the public and waste workers. Waste workers are exposed to potential needle stick injuries and potential infection when inappropriate containers break open inside garbage trucks or sharps become exposed when sent to recycling facilities. Housekeepers and janitors may also be injured when loose sharps poke through trash bags. Used needles can also cause painful infections and transmit serious diseases, such as HIV and hepatitis.
The Law
Beginning on September 1, 2008, State law made it illegal to dispose of home-generated sharps waste in the trash or recycling containers, and requires that all sharps waste be transported to a collection center in an approved bio-hazard sharps container.
The California Health and Safety Code defines “home-generated sharps waste” as hypodermic needles, pen needles, intravenous needles, lancets, and other devices that are used to penetrate the skin for the delivery of medications derived from a household, including a multifamily residence or household.
Residents can visit the California Department of Resources Recycling and Recovery (CalRecycle) website to find out if the pharmaceutical manufacturer has a free sharps container available. Senate Bill 486, passed in October 2009, required that by July 1, 2010:
“…all pharmaceutical manufacturers that sell or distribute a medication in California that is usually intended to be self-injected at home through the use of a hypodermic needle, pen needle, intravenous needle or any similar device, to 1) submit a plan describing their actions to support or provide for the safe collection and proper disposal of the waste devices, and 2) educate consumers about safe sharps management and collection opportunities.”
The CalRecycle website that lists the manufacturers who have turned in a plan is www.calrecycle.ca.gov/homehazwaste/sharps/reporting/default.htm
If residents need more containers they can ask the pharmacy where they get their medications. For further information about obtaining biohazard containers or mail-back programs (most of these companies charge a fee for the containers):
