My kids are 16 and 14, we've discussed it at length. Both my wife and I smoked cigarettes, I quit 5 years ago, she quit almost a year ago. I explained to them, that although I don't inhale the smoke, it's still not a 'healthy' activity. But at the same time it helps me relax and relieving stress is also important. They seem to understand the difference and they both think it's 'gross', so I guess I'm doing my job by informing them, not necessarily preaching to them. I preach to them about so many other things...
