This mornings NY Times carries an article entitled “The Selling of Attention Deficit Disorder” can be read here. The essence here is that although 5% of children may have the syndrome called Attention Deficit Hyperactivity Disorder or ADHD, as many as 15% are give stimulants upon a diagnosis " of scant symptoms." Dr. Keith Conners says that the rise in diagnosis from 600,000 in 1990 to 3.5 million in 2013 is a "national disaster of dangerous proportion."
It seems that in a case of actual ADHD, the administration of Adderall or Concerta actually has a calming effect. However,when those same drugs are administered to someone who doesn’t have ADHD, the drugs act as the stimulants they are. This is why professional athletes are seeking therapeutic use exemptions that allow such use. As shown here; MLB has granted such exemptions to, curiously, 15% of its players. As has been written here as well, the drive to excel and use drugs to do so is prevalent in sports and the use of the therapeutic use exemption is simply one more method by which players mask their use of drugs, this time hiding in the open.
