Right. That and I know very few doctors that are paid millions of dollars.
It may not enhance performance on the field but it does in the classroom. Players have to study the playbook and a lot of film in their spare time. Adderall keeps them awake and able to focus and cram a lot of information. Adderall is a well known 'study drug' on university campuses.
(College campuses known to be highly competitive had up to 25% of students use an ADHD medication within one year, a survey of students at 119 colleges across the country concluded.) - From Wiki
Depends on how the Adderall is being used as well. I was reading an article on Adderall a moment ago and apparently snorting it gives the same effect as cocaine. It would seem very plausible for a player to attempt to get an edge by doing this. Also, one of the common side effects is aggressive and hostile behavior which would definitely be beneficial on the football field. I guess forsaking long term health for a short term gain more than the players already are is worth it in their eyes.
Interesting discussion, I think Brown gut the buy early because it wasn't well known after his suspension and subsequent reinstatement. I think Goddell might feel that everyone has been warned and if you have a prescription then you need to let the NFL know about it!
Its really not. From personal experience its not. The only think I can think of, which another poster brought up, is trying to memorize the playbook.
Adderall is an amphetamine. It increases your heart rate so when you run around you feel winded much quicker than you normally would. Not to mention how bad that is for your heart. I used to play lacrosse on all sorts of drugs, and these ADHD amphetamines were never of any help.
