Of the 113 Therapeutic Use Exemptions granted this year in baseball, all but two were for attention deficit disorder, according to the annual report from the Joint Drug Prevention and Treatment Program's independent program administrator.
Major League Baseball and the Players Association released the annual report on Tuesday.
The annual report covers the start of the 2014-15 off-season through the end of this year's World Series. The total number of tests conducted for the presence of performance-enhancing substances, stimulants and/or DHEA were 8,158, up from 7,929 last year. That included 7,630 in-season tests and 528 off-season tests.
There were 1,349 players who appeared in big league games this year, including the postseason. That means 8.4 percent of that number had exemptions.
The total number of urine tests was 6,536. The number of blood tests for HGH was 1,622.
Ten of the tests this year resulted in discipline, seven for performance-enhancing substances, two for stimulants and one for DHEA.
The number of Therapeutic Use Exemptions, 113, remained the same as last year, but notably, 111 of them were exemptions for ADD drugs.
