The Effects of Pill Mill Legislation on Suicides

I want to move on now to a paper that you did that's titled the effects of pill mill legislation on suicides. And this is also a topic to which you have a very connection. You shared with me before our chat to day that your grandmother died by a suicide in cuba. I guess i'm wondering if there's a back story to your research on suicide as well, because you have done multiple papers on this topic.
