One of the biggest problems with early drug use prevention programs is that they tend to be largely based on threatening or trying to scare young people. This is often done by adults who have experimented with drugs themselves with few dire consequences. Kids tend to be able to pick up on hypocrisy and exaggerations quickly and often tune out. Most older teens and young adults realize that if they try marijuana it is very unlikely they will end up strung out on heroin. They tend to try it or not try it for their own more rational reasons. Discuss your feelings on a more fact based and student centered approach.
