About Open Mind
Harm reduction through knowledge
Our Mission
Open Mind was created with a simple belief: people deserve access to accurate, non-judgmental information about psychoactive substances. We recognize that substance use is a reality in our society, and we believe that education and harm reduction save lives.
Our goal is not to encourage or discourage drug use, but to ensure that people who choose to use substances can do so as safely as possible. We provide evidence-based information on dosages, duration, interactions, and safer use practices.
What We Offer
Comprehensive Database
Detailed information on 500+ substances including dosages, duration curves, and subjective effects.
Combination Checker
Check drug interactions before mixing. Know which combinations are dangerous.
Safer Use Guidelines
Practical harm reduction advice from set & setting to emergency protocols.
Privacy First
No accounts required. No personal data collected. Your usage stays private.
Our Approach
We follow the principles of harm reduction - a set of practical strategies aimed at reducing negative consequences of drug use. We don't moralize or lecture. We provide facts and let people make informed decisions.
All information in Open Mind is based on scientific research, clinical data, and community knowledge. We continuously update our database as new research becomes available.
