Terms of Use

This site is for adults of legal drinking age in their jurisdiction. It is not directed at minors, and nothing on it should be read as encouragement to drink.

Every number this site produces is an estimate computed from population averages. No page here measures your blood alcohol concentration, and no page can. Results are ranges with substantial margins of error, as described on the methodology page. You must not rely on any output of this site to decide whether it is safe or lawful to drive, operate machinery, work, breastfeed, or do anything else where impairment matters.

Nothing on this site is medical advice, legal advice, or a substitute for either. For questions about your health or medications, ask a doctor or pharmacist. For questions about legal limits and consequences, ask a lawyer or your local authority.

The site is provided as is, without warranties of any kind. To the maximum extent permitted by law, the operator accepts no liability for any loss or harm arising from use of, or reliance on, this site. Decisions about drinking and driving are yours alone, and the only decision this site will ever endorse is: never drive after drinking.

Content may contain errors and is updated without notice. External links, including links to other sites in the same portfolio, are provided for convenience; their content is their own responsibility. Cited organisations such as NIAAA, NHTSA, and publishers of the referenced research have not reviewed or endorsed this site.
