I let my 16 year old do it. It keeps him home and it keeps him safe.

I told him if he brings friends over to smoke, act like your sneeking around me and that I do not know.

And never....and I mean NEVER......let your friends know that I smoke or that I let you smoke or you'll be grounded and I'll confiscate your stash.

I also smoke with him ....when my wife is not around. She smokes as well but would kill me if she knew I smoke with my boy. She'd never understand....It's a father / son bonding thing.
