that's exactly what me and my wife did to protect our toddler from drug addiction. We started him on light marihuana since two, only later introducing other drugs like MDMA, amphetamines and very sparingly cocaine. Hope this exposure helps him never to get addicted.

You can't learn to resist hard drugs, and such drugs causes great damage on growing bodies. So no, your example isn't comparable.

Banning candy for your kid is a more apt comparison, and that seems to be very ineffective to me.

I'm not sure if he's joking or serious! In any case sorry this has to be said but no don't give drugs to kids please.
