Drug checking is an essential harm reduction service that enables people to know what’s really in their drugs. With even the smallest amount of drug product, we can use multiple kinds of technologies to provide both point-of-service and laboratory-based drug checking opportunities. Point-of-service drug checking can be done in about 10 minutes, while laboratory-based methods may take 4-6 weeks.

By knowing what is in your drugs before you use them, you can be better prepared by expecting the unexpected. For example, you may be able to avoid harmful adulterants, like fentanyl or xylazine, or to know to be on the look out if your drugs are more potent than usual.

Our services are always free, totally anonymous, and completely legal. Drug checking in California was explicitly legalized on January 1, 2025, offering a number of protections for those choosing to get their drugs checked. For example, under AB 2136, it is legally permissible to have a personal amount of drugs if you are en route to or from drug checking.

Our team has produced various research publications and has been covered in media.
