BTYBD is a harm reduction reference tool built on peer-reviewed clinical research. It provides factual, evidence-based information about psychoactive substances to support safer decision-making.
This app does not promote, encourage, or facilitate drug use. It exists because people who choose to use substances deserve access to accurate safety information — not misinformation.

WHY THIS APP EXISTS
Harm reduction saves lives. Organizations like DanceSafe, The Zendo Project, and MAPS have demonstrated that access to accurate information reduces emergency room visits and fatalities. BTYBD puts that knowledge in your pocket.
Every data point in this app is sourced from peer-reviewed research or established harm reduction organizations. No anecdotes. No promotion. Just evidence.
