“Smart drugs” — stimulants prescribed for Attention Deficit Hyperactivity Disorder — are popular college study aids, reports NBC News.

A Boston University Student named Wyatt, said everyone he knows uses drugs like Adderall, Ritalin, Focalin, Vyvanse. “You can go up to the second floor of the library and see, you know, a full wing of people just cracked out.”

In my day, we used caffeine: No Doz, now marketed as an “alertness aid,” was popular.

Nearly one-third of college students have misused stimulant prescription drugs at least once, according to the Center on Young Adult Health and Development. They tend to have lower grades and be more likely to skip classes.

Stimulants don’t  help children with ADHD complete homework or get better grades, according to a Florida study, reports Reuters’ Lisa Rapaport.

Children who received medication did no better than those who got a placebo.

Providing daily report cards for kids and coaching parents to help with homework did make a difference: Students improved enough to raise their average grade from an F to a C.
