Some people are more prone to addiction - that much we know. What we don't know for sure is why. A new study has found evidence that some teenagers are at higher risk for substance abuse because their brains work differently, in ways that make them more impulsive. The same study has also found that different networks in the brain seem to be connected to symptoms of ADHD. We talk with Hugh Garavan, an associate professor of psychiatry and psychology at UVM, and senior author of the paper, and Robert Whelan, a post doctoral researcher at UVM in the department of psychiatry and psychology, and lead researcher on the study.

Also on the program, we'll talk with Gloria Bruce, Executive Director of the Northeast Kingdom Travel & Tourism Association, about the challenges and benefits of promoting tourism in the Kingdom while preserving the unique character and way of life of the region.
