I have heard a number of statistics about the current generation of young people smoking less and drinking less than previous generations. Here's a great story to back up the statistics:
The school council at Eythorne Elvington Community Primary School in Dover raised the issue of smoking by parents at the school gates, leading to the head asking parents to improve their behaviour in the school newsletter.
Go, kids, go! Let's get these kids sorting out world peace, too, I'm sure they can do a better job than our generation.
