Substance use prevention has changed substantially over the last 20 years. We now know that "just say no" and programs like DARE don't work. Not only do we now know what programs work, we know which ones are likely to give the most bang for the buck. We also know what kinds of public policies work to create healthy environments that support positive youth development. Substance abuse, like most public health problems, needs a comprehensive solution that includes prevention.
