And In Medical News (A rant from a non-smoker):
Passive Smoking Raises Carcinogen Levels In Urine Rapidly
A potent carcinogen rises quickly in restaurant and bar workers' urine after even brief exposures to secondhand smoke, a new U.S. study finds. [...] Three of every four employees working where smoking was permitted had detectable levels of NNK [cancer-causing toxin], compared to fewer than half of those in no-smoking establishments, the researchers found.
Another report in the same issue of the journal noted that employers are increasingly likely to be held legally liable for exposing workers to secondhand smoke, even in localities where laws permit workplace smoking.
The legal analysis, from the Public Health Institute in Oakland, Calif., found that workers harmed by secondhand smoke are turning to worker compensation laws, state and federal disability laws for redress. It is now employer's responsibility "to provide a safe workplace" to have smoking banned where they work, the researchers wrote.
In the end, cigarettes result in lives lost, more costly health care, legal bills, and cash wasted on a self-imposesd habit. I played at smoking as a teenager and amused my friends by blowing smoke rings. Nothing about smoking turned out to be very amusing.
