In addition to treatment of juveniles with ADHD, Adderall is sometimes prescribed for children who are not doing well in school but who don't have ADHD. These are often children from economically-deprived backgrounds for whom alternatives such as therapy or tutoring is not available.
Adderall is widely used as a "study drug" at many universities, due to Adderall's reported ability to help focus energy and concentration to a much higher level than normal. It enables the user to focus and stay awake. Stories of students writing papers continuously for an unusually long time or "cramming" all night for an exam with no loss of energy or concentration are common. College campuses known to be highly competitive or have a high rate of binge drinking had up to 25% of students use an ADHD medication within one year, a survey of students at 119 colleges across the country concluded.
Adderall use as an academic advantage has become increasingly common amongst college students. Illegal Adderall use is highest among students from the northeastern region of the United States and students from colleges with more competitive admission standards. Students with ADHD sell Adderall on college campuses for anywhere from $5 to $25 a pill depending on the time of the academic year. The legal consequences for selling Adderall include prison time because it is classified as a controlled substance. It is often difficult to catch illegal Adderall sales because the pills are “easily concealed, odorless, and can be perceived as prescribed drugs” Of these sales, 62% of buyers report using Adderall for concentration and study help.
Many athletic organizations have restricted the usage of Adderall by athletes. The NCAA has banned the use of Adderall for its collegiate athletes without a prescription and adequate records of evaluation and diagnosis of ADHD. Nevada State Athletic Commission has also banned athletes in the state from using Adderall. Tim Credeur was removed from a UFC fight on the finale of The Ultimate Fighter 7 because of a positive drug test due to his use of it. In the National Football League, New Orleans Saints kicker Garrett Hartley served a four-game suspension when the 2009 NFL regular season began because he tested positive for the banned stimulant. The Arizona Cardinals tight end Ben Patrick received a four-game suspension as a result of using Adderall.
The New York Giants running back Andre Brown (American football) faced a four-game suspension for violating NFL's performance-enhancing substance ban. Brown said: “It was something that I've been on since I've been in the league, which was Adderall. I just forgot to fill out some paperwork and that was it.”  Brown eventually won an appeal, and had his suspension lifted. Another Giants player, Tyler Sash, was suspended for four games by the NFL in July 2012 after testing positive for Adderall four months earlier. The safety said in a statement that he took the drug legally and "under a doctor's care for an anxiety condition" to help him with public speaking. The New York Giants safety Will Hill (American football) was charged a four-game suspension for violating NFL's performance-enhancing substance ban. Hill said: “"I received a doctor's prescription for Adderall prior to signing with the Giants”  Tampa Bay Buccaneers cornerback Aqib Talib has been suspended four games by the NFL for violating the league's policy on performance enhancing substances. Talib released a statement saying his suspension was a result of testing positive for Adderall: "Around the beginning of training camp, I made a mistake by taking an Adderall pill without a prescription,".
