Poker Players Use Performance-Enhancing DrugsA new study from Nova Southeastern University has revealed that 80 percent of the 198 players interviewed reported using drugs and other substances to enhance their performance.

The drugs, generally, were marijuana, cocaine, amphetamines, Valium, and other prescription medications, as well as caffeine, energy drinks, and guarana.

Kevin Clauson, Pharm.D, an associate professor at NSU’s College of Pharmacy, who was the principle investigator in the study, said the higher stakes the game, the more likely the use of substances to enhance performance.
