You should start an educational program with that piece of sage advice. Not the kind of message I'll be passing onto my offspring.
That's EXACTLY the kind of drug education that doesn't work though.
Kids are told "drugs are bad, take an ecstasy tablet and you'll die, smoke weed and you'll end up on crack" etc.
Then they try it once, they realise it's not so bad and that no only did they not die, they felt better than OK.
So, armed with absolutely bugger all USEFUL drug education and obviously no chance of approaching their parents for advice, they embark on a recreational drug adventure, discovering things by trial and error.
Far better to prepare kids for the reality. Not all drugs are evil, most in fact are pretty safe if basic rules are followed (unless of course you're disputing Nutt et al)..."Like alcohol, all drugs can be extremely dangerous, there are some basic rules and safe guidelines which you MUST always pay attention to....".
My kids will be told about recreational drugs in the same way they are told about alcohol.
Trying to keep kids from trying drugs by saying they are bad is about as effective as trying to stop a train with your teeth. Arm your kids with the ability to make their own decisions and give them the knowledge they need to keep safe. The rest is completely out of your hands.
