Knowledge should never be gatekept.
Where these answers come from
Most combinations come from the TripSit drug combination chart, a peer-maintained harm-reduction dataset, retrieved 2026-08-20. Pairs it does not cover are filled in by our own research, each with citations. Everything else is reported as no data — which is not the same as safe.

Our mission
MixSafe — written Mix Safe by about half the people who look for it — exists to reduce harm through education. We believe that understanding is the first step toward safety, especially when it comes to substance use. Many people mix drugs unknowingly, unaware of the risks involved. Our mission is to provide clear and reliable information, so people can make informed, safer choices.
Why we built this
As college students, we’re constantly surrounded by a culture where drug use, recreational or otherwise, is common yet rarely discussed in honest terms. Searching for help can feel embarrassing or even risky. We built this tool because we believe knowledge should never be gatekept. This site doesn’t promote drug use; it promotes informed decisions, reduces misinformation, and encourages responsible behaviour in an imperfect world.
Who we are
I’m Elijah, a student of computer science and philosophy who believes that technology can serve as a moral tool. Safe drug use is something I care deeply about — not just because of its importance to health, but because I believe every person deserves access to knowledge that can protect their life. This project is a reflection of that belief.
