Re: hello all!
If he is not a minor I withdraw my comments. I don't hope to change his behavior in any case but I think that what is not helpful is to condone violating the laws about about minors and smoking which is what we do when advice and implicit approval is offered to under-aged smokers. Frankly, I don't want to give anti-smoking forces more ammo to use against us.
If he is not under-aged I say the thing to do is to tell his parents about it and give them a little lecture about the wonders of our hobby. I do think that most non-smokers will notice the smell and it will cause problems so best get it out in the open.
