Terms of Use and Privacy

By using this site you agree to these terms. They're short, and we wrote them in plain English.

Information only
Content is general information, not medical, legal or employment advice. Talk to a doctor, pharmacist, medical review officer (MRO) or lawyer about your situation. Don't use our content to tamper with any test; doing so can be illegal and is usually treated as a refusal to test.
Privacy
We use privacy-friendly Cloudflare Web Analytics where enabled, and a first-party cookie that lets us count real clicks on affiliate links and filter out bots. We don't sell personal data. Affiliate partners have their own privacy policies.
Calculators
Our calculators give rough estimates based on published averages. They can't predict your result and must never be used to decide whether you're safe to drive.
No product can promise you a pass, and the only certain way is to not use. Tampering with a drug test can be illegal and is usually treated as a refusal. We never help anyone beat DOT, federal, safety-sensitive, or court-ordered tests. If substance use is getting on top of you, call the free, confidential SAMHSA National Helpline on 1-800-662-4357 (24/7, English and Spanish), or call or text 988 in a crisis. Source: samhsa.gov.
