I'm not an expert, but I have a professional interest in the brain and behavior, as I work with a lot of kids in special education.

I use stuff that is pretty clear, concise and comes from medical and scientific sources. I'm subscribed to Web MD, for instance, and use it probably more often than any other source when it comes to do some quick and preliminary research, and sometimes for more in depth reading about a particular study.

My interest isn't really in addiction at all, but kids and their learning disabilities, and what does and doesn't work in helping them. Because so many kids with learning disabilities had parents with substance addictions that wreaked havoc with their brain development in utero, you can't really get into the search for what will help them, until you know something about what has hurt them to begin with.

That said, someone I greatly admire and whose scholarship I respect is Bill Moyers. He did a very good program on addiction for PBS awhile back. There is still good information from it here.

I first became interested in all this when I was attending university in the 1990s, and worked for a neurosurgeon at the university's hospital.

So there you have it.
