A BAR-O-GRAPH nomograph of blood-alcohol concentration in percent
has been designed to assist in determining when enough is enough.
Various states have different levels of blood-alcohol concentration for
legal defi nitions of intoxication. At the time this nomograph was prepared,
the offi cial BAC level in California was 0.1%. If you weigh 140 pounds or
fewer, it would not appear to be prudent (or legal) to drink more than two
Manhattans within an hour at the ORSA mixer tonight if you plan to drive
shortly thereafter.
