I'm a high school teacher, so whether I want to be or not, I'm sort of a role model for the kids, especially the guys. For whatever reason they feel free to admit their vices in passing or directly, and lots of the guys are already vaping or dipping or chewing or smoking. Two football guys were debating one day over dipping versus smoking cigarettes. The big linebacker dips, the skinny running back kid smokes. The linebacker was telling the running back he wouldn't be able to breathe in about 30 years and the running back said the other would have mouth cancer. Another kids was saying he didn't vape, that he was "au naturale" and smoked cigars. Another kid said he could smoke four cigarettes between his house and the school, in the span of 10 miles. Many other examples, but point made. They've already picked all this up from their dads, peers, granddads, and so on. And then the football coaches are dipping and chewing and spitting juice everywhere at practice, so that is probably a factor.
That said, I don't openly advertise that I myself smoke a pipe or cigars or cigarettes although if asked I would not lie. I would tell them the pipe, which is my favorite nicotine delivery system. My white beard is yellowed around the mouth and I probably smell more strongly than I think of dark Kentucky or Burley/Perique when I come in in the morning, so it should/would/could not be hard to figure out what I am doing. They have said that my classroom smells like "old wood" when they walk in first thing, which must be what scent someone carries who has been smoking the above mentioned tobaccos.
I can't really lecture them about something I do and that I have currently chosen not to give up myself although I have mentioned if asked that they should go ahead and quit habit X while they are young since it is easier than later. Their first assumption would be that if anyone smokes, it would be cigarettes or cigars, and I don't know that the pipe would ever occur to them as an option. These local tobacco/vape shops around here generally have almost no pipes, or if they do, it might be a few corn cobs or those plastic ones. Still haven't figured out how those are even smoked. Anyway, I have never tried to steer someone onto pipes although I did tell a kid who said he was heavily vaping that dipping might be a better option, but he said he didn't like dip. I asked him if he had swallowed the juice. He said yes.
I would have a problem with putting someone onto tobacco in any form who wasn't already into it. If I'm being honest, I know it will probably catch up with me at some point if it hasn't already. And if you never try it, you don't know what you are missing. but if you do try it, there is a very good chance you will really like it, in whatever form. We all know the 80 year old guy who smokes and is still healthy, and we all know someone who got lung cancer at 50. You just don't know how it will turn out.
