Answering the Libertarian argument for drug legalization

[eman]

When i was a scout leader ,we had a drug counselor volunteer to come in and talk to our cub scouts about the dangers of drugs. Once he started talking i realised that he was just quoting facts and figures that came from books.
The boys looked like they were bored out of their minds, so interrupted him and asked him, What real life experiences can you tell these boys
about the dangers of using drugs? he stated that he had never taken a drink or used any drugs in his life. I told him thank you and that he was no longer needed to speak at this time.
he lost it. Tried to explain that he knew all about how drugs worked and what they could do by studying books.
He left and 3 weeks later we had an addict who had lost his family and done prison time because of cocain come speak to the boys. He made his points and did it w/ purpose. The boys paid attention when he spoke and it seemed to me were absorbed in it.
