i would like to know how this turned out for OP.

for me its important to be honest. tell them everything, good and bad, and they will find their own path.

if you are not open with them you are going to have to sit back and watch the less informed parts of society do the education, which is where the alcohol, heroin, coke, etc sneaks in, particularly for kids who are in an area where that is everywhere.

as far as convincing other adults that this is the best thing to do for them, thats a whole different fight, a much more difficult one to overcome. i think the conversation still needs to be had though, the more people speak up the more accepted it will be and we can all move forward.
