Jeff Jenson, University of Denver, discussed progress and gaps in prevention practice, policy, and science. He referred to a power point during his presentation (Attachment L). He discussed the history of drug prevention strategies, such as "Scared Straight" and "Just Say No." He pointed out that these programs were not effective in decreasing drug use or delinquency. Mr. Jenson discussed effective prevention programs that focus on interventions that reduce risk factors and increase protective factors. He suggested that universal prevention for all young people is the most effective way to reduce substance use.
