For years teens and college students have been using medication intended for treating symptoms of Attention Deficit Hyperactivity Disorder (ADHD) as study aides.  The medications tend to be stimulants that increase concentration and energy in people who do not have ADHD.  Teens use them to study all night long, cram, or to study for subjects that are boring to them.  Obviously teenagers self-administering stimulant medication is very concerning.  Without the supervision of a psychiatrist is it easy for teenagers to overdose. They may combine these drugs with other medications that may have dangerous consequences for them.  Teens have also been known to develop symptoms of depression because of this medication, something a psychiatrist should definitely be aware of.
