I recently did an assignment for PE and Health to build a resource list to teach a unit on substance abuse, so an article in this week's Cambridge Times caught my eye. Former drug addict, gang member, outlaw biker, and convict Rick Osbourne gave a talk on the dangers of drugs, gangs and prisons. It was part of a In the Minds Eye http://www.inthemindseye.ca - an annual series of events and forums presented by the Waterloo Region Community Safety & Crime Prevention Council. Rick now holds an addiction careworker diploma and a psychology degree. The web site has a bunch of local resources, and you can perhaps track down Mr. Osbourne for a guest speaker through them.
