Smoking bans are sweeping the nation -- just witness Pennsylvania -- making many smokers more than a little jittery. But what if there was a way to deliver what smokers crave without the smoke, the smell or all those nasty carcinogens?

That's what a new product being marketed in Nevada and Colorado does, although the jury is out on its potential health risks. Njoy was developed by patent attorneys who saw a marketing opportunity in the spread of smoking bans.

Their pen-shaped device uses a battery and micro-technology to deliver tobacco-flavored, mentholated or fruit-flavored mist to the smoker's lungs. There's even a no-nicotine version. And because there's no smoke -- and therefore no secondhand smoke -- the devices often can be used in places where smoking has been outlawed.

Njoy is not a smoking-cessation device, but a way for smokers to mainline nicotine, the primary addictive substance in tobacco products, without some of the risks associated with those products, like bronchitis, emphysema, lung cancer and heart disease. Taking the deadly chemicals out is a positive, but the addiction remains and addictions are inherently bad.

If this product truly were benign, it would not carry a warning against use by nonsmokers, pregnant women, children and people with various illnesses. At the very least, it reinforces the user's addiction to nicotine. Which raises the question, why feed the habit when you can kick it?
