Psychology is confronted by numerous issues and challenges today. One of which is the debate over the use of prescription medication for mental health illnesses. Over the past decade, one in five adults was prescribed a psychiatric drug such as antidepressants, antipsychotics and anti-anxiety medications. Prescriptions for psychiatric medications grew twenty two percent for adults between 2001 to 2010, and prescriptions for ADHD drugs such as Concerta and Vyvans tripled among adults twenty to forty four. This is a significant increase, especially when considering that prior to 1987 when Prozac came to the market, U.S. mental illness disability rate was one in every one hundred eighty four Americans, compared to one in every seventy six in 2007.
