Make A Payment or Donation to Erowid's DrugsData Project
Support Laboratory Drug Checking / Analysis

If you are making a payment for lab analysis, please see the DrugsData Send Page and Read the FAQ The cost of analysis is $100, $150, or $200. Your support will help Erowid Center continue its efforts to:
  • Anonymously analyze recreational and psychoactive drugs including ecstasy/molly tablets, novel psychoactive substances (NPS), and opioids
  • Collect data about how these psychoactive drugs are represented
  • Make laboratory test results available to the public
Donations of any size are welcome. Each analysis costs Erowid Center $150 in direct external costs. Due to budget limitations, co-payments are required for most samples. See DrugsData: Send Sample.

Erowid's DrugsData lab drug checking project costs $90,000 per year. This covers the testing of approximately 45 samples per month, with $100/$150/$200 co-pays supporting the project. We could test many more samples and provide a much greater harm reduction impact with more funding. If you are a fundraiser or grant writer, we need your help to find funding for this project.
