The dose makes the poison inferred
A reported rat oral LD50 for Ethanol is 5,628 mg/kg, the dose lethal to half the animals tested. Scaled by body mass alone:
“The dose makes the poison” is a cross-species estimate shown as neutral science, not a threshold anyone should act on. Real toxicity depends on the person, not body mass alone.
Blood-alcohol estimate computed
The only molecule with its own alcohol math. A rough Widmark estimate from what you drank:
Estimate only. The Widmark formula ignores food, drink strength, metabolism, and medication, and it is never a basis for deciding whether to drive.

Where Ethanol leads
Ethanol is the one recreational drug humans have fermented for at least nine thousand years. The body clears it at a roughly fixed rate, about one standard drink per hour, which is why its math is a Widmark BAC curve rather than a half-life decay.
