Contact Us
Found a numerical error in one of our detection estimates? Have a question about the pharmacokinetic model or how the cutoff levels work? Want to suggest a topic for our blog? Email the editorial team directly. We read everything and reply to substantive questions about the research and methodology.
What We Can Help With
Most of the email we receive falls into one of a few categories. Here's what we're best positioned to answer:
Tool errors or bugs
Noticed a result that looks wrong or a page that won't load? Send us the exact inputs you used and the result you saw. The more specific, the faster we can reproduce and fix it.
Methodology questions
Want to understand how we derived a formula or why our estimate differs from something you read elsewhere? We'll walk you through the underlying calculation and the source it draws from.
Blog topic suggestions
Seen a question about EtG testing that our blog doesn't cover? Tell us. Our editorial calendar is partly driven by reader questions we see repeated.
Factual corrections
Spotted an out-of-date reference or a number that doesn't match current literature? Cite the paper you're reading from and we'll review and update the affected page.
What We Can't Help With
We're a research and editorial team, not a medical, legal, or clinical service. Please don't email us for:
- Personal medical advice about your specific situation
- Legal advice about probation or court-ordered testing
- Predictions of whether you will pass or fail a specific test
- Requests to help circumvent legitimate sobriety monitoring programs
For questions about your specific case, speak with your healthcare provider, attorney, treatment counselor, or probation officer. They have context about your situation that we don't.
Before You Email
Many common questions are already answered elsewhere on the site. It's worth checking these first - you'll usually get a faster answer:
- The EtG calculator itself (for detection-window estimates).
- Our blog library (covers detection windows, cutoff levels, false positives, and more).
- The About page (explains our methodology, sources, and editorial process).
- False-positive causes (if you're asking about mouthwash, hand sanitizer, or foods).
If you've already checked these and still have a question, send us an email and we'll get back to you.
