Dear Erowid Readers: We're a small nonprofit that runs the top drug information website in the world. We have only 4 staff but serve 12 million users, and have costs like any big website: servers, power, office space, programs, and staff. To protect our independence, we don't run ads or take government funds. If everyone reading this gave $3, our fundraising would be done today. If Erowid is useful to you, take a minute to keep it online and ad-free another year!

We enjoyed reading Haller et al. recent evaluation of a novel assay to detect urine gamma hydroxybutyrate GHB concentrations 1. Although this study was well-designed, using a double-blind, four-arm, crossover design, we have some concerns over their results.
