I would never encourage a non-smoker to take up vaping, but if they decided to then I also wouldn't discourage them. If they asked for advice though, I would advise them to stick with 0-nic eliquids. The kind of person who wants to take up vaping is the kind of person who might alternatively have taken up smoking. So maybe it's not a bad thing.
As for vaping leading to smoking - I can't see that really happening. The flavours when vaping are so nice and so varied. Even as a recent smoker, I hate the taste of cigarettes now. I can't imagine a non-smoker would be attracted to cigarettes just because of the similarities in the hand-to-mouth habit.
