A survey of college students finds 29 percent mistakenly think drugs used to treat attention deficit hyperactivity disorder (ADHD) increase school performance.
An additional 38 percent are unsure of the drugs’ effects on school performance, HealthDay reports.
There is no evidence that stimulant medications such as Ritalin and Adderall are effective study aids, the article notes. The survey included almost 7,300 students, none of whom had been diagnosed with ADHD.
The belief that stimulant drugs increase school performance was especially high among students who misused the drugs. Among the 11 percent of students who said they had used stimulant medication for non-medical reasons in the past six months, almost two-thirds believed the drugs would boost their grades.
The findings appear in the journal Addictive Behaviors.
