I'd educate them on it with fact, and tell them not to listen to the Government - because it's lies. I'll let them smoke at any age - it doesnt bother me because i know it's safe - but they wont be allowed to smoke in my house untill 16. And i wont give them money for it - if they want it they'll have to be responcible and get a part time job or something. Also i'll let them into my secret of growing - and they can have a plant or 2 for themselves.

I wont say anything about growing untill they are at least 16 though, because i need to be able to trust them not to go bragging - kids are good at saying what you want to hear but not following it through.
