How Much Second-Hand Smoke Are You Inhaling?

It's called "Tobacalert" and with a simple urine sample it measures a person's tobacco exposure.

We tested it on Jeff Trost, a non-smoker who works at a diner. His test strip read a level of six which is the highest level exposure.

The product is not approved by the Food and Drug Administration so we also tested its accuracy on a WILX producer-also a non-smoker. His test strip read "level one," which means very minimal exposure.

The American Lung Association does not endorse products, but says second-hand smokes causes 3,000 deaths each year. A spokesperson there says Tobacalert may be a good tool for a lay-person to determine how much smoke they're inhaling.

Doctors say the most accurate tool is still a blood test. Tobacalert can be found at CVS for $15.
