nope. wait till their 15 or 16. esecially now. im 16 and when i was 10, i was put through the DARE program and had a period for about 6 months where i was incredibly anti-drug. they brainwashed me, but then two years later, i gave in and got high. when they turn 15 or 16, ask them about smokin and tell them that your okay with it. if there still anti-drugs, dont tell them. and if they smoke to, pull out a blunt and spark it up
