Depression and drugs might be the two thorniest topics out there. Depression is something that everyone experiences in some quantity, but only some at a clinical level. Depression varies culturally in its prevalence and treatment, and in the United States, doctors are often quick to prescribe medication for it. Of course, other people don't get their medication from a doctor, but instead turn to their local bar or dealer.
We're not at the point of knowing the right answers with any certainty when it comes to depression, drug use, and where to draw the line between therapy and pathology. What we do know is that a better public understanding of the research will help to move this thorny but fascinating conversation forward.
