Good topic, Porty. I've been thinking about it on and off all morning.
Openness is generally the favoured approach in our family, but like you I know others where that's worked and others where it hasn't. Openness was not a policy in other half's family; other half never touched recreational drugs aside from alcohol, but her brother did. Nor was it a policy in my family; I haven't done it (but not for any moral reasons, just personal ones) but one or two brothers have. Having said that, as one of the E generation, there are very few friends who haven't. I still feel that Mr M is right though and openness and information are the best things we can give.
I recently had some training on drugs (no, not on drugs) and we did an exercise called the circle of harmfulness where we had a list of eight, or maybe ten, drugs, and we had to divide a circle up into sections according to which we thought were the most harmful. Everybody put heroin down as the worst thing. Most people put cigarettes and alcohol as the least damaging. Since that is the opposite, at least physiologically speaking, of the truth, maybe we all need much more education. Alcohol does the most damage to your body and arguably has the biggest social and economic consequences...yet everyone thinks it's ok because it's legal. And actually a lot of the kids know better than we do about this stuff.
