Studies Show ADHD Drugs Misused by Adults


— June 13, 2025

Misuse of Adderall, Ritalin and other ADHD medications by healthy individuals can be downright dangerous.


Some high-performing professionals have been turning to prescription ADHD medications, hoping for a mental edge. These drugs, meant to help people with attention disorders stay on task, are now being used by students, lawyers, athletes, and others trying to boost focus or energy. But when people take ADHD drugs without actually having ADHD, they often get more than they bargained for — and not in a good way.

Stimulant medications like Adderall and Ritalin are designed to help regulate the brain’s dopamine system. In people with ADHD, dopamine levels are too low, which makes it hard to concentrate, manage time, or control impulses. These drugs increase dopamine to a level that makes everyday tasks easier. But if a person already has normal dopamine levels, these medications push the brain into overload. Instead of better performance, the result is often worse focus, poor memory, and even emotional crashes.

Some people feel more awake or driven when they first take these drugs without a diagnosis. But that feeling doesn’t last. Research has shown that so-called “smart drugs” can actually reduce performance in problem-solving and memory tasks, even though the people taking them feel like they’re trying harder. In one study, people who took Adderall or Ritalin scored lower than when they took nothing at all. They were more active and focused — just not on the right things.

The physical side effects can be troubling, too. Even at low doses, these drugs can raise heart rate and blood pressure, affect sleep, and reduce appetite. People sometimes feel jittery, irritable, or unusually tired by the end of the day. Over time, the body can build up a tolerance, which means higher doses are needed to feel the same effects — increasing the risk of more serious problems. In some cases, long-term misuse has been linked to heart issues, anxiety, and depression.

This is why ADHD medications are banned in sports unless a person has been officially diagnosed. But more athletes are being diagnosed with ADHD as adults, and that has raised eyebrows. Some experts believe the condition might be underdiagnosed in sports, especially since people with ADHD often do well in physically demanding settings. Others worry about abuse and fake diagnoses, since having a medical reason allows athletes to legally take these drugs when others can’t.

There’s also a growing trend of people getting pills from friends or family, especially during stressful times like exams or big deadlines. Parents have even taken their children’s prescribed stimulants, believing it will help them function better at work or home. But this kind of misuse carries the same risks as any other. The brain and body don’t care whether the pills came from a doctor or a friend.

Experts say the long-term solution is better education about what these drugs actually do. People often assume that if a medication works for someone with a disorder, it must help everyone. But that’s not how it works. The drugs are meant to fix an imbalance — not to give an extra edge to someone who already functions normally.

Misusing ADHD drugs may seem like a shortcut to success, but the evidence shows it’s more like a detour to worse outcomes. The brain needs balance to work well. When that balance is pushed too far, the system breaks down — and the person trying to get ahead can find themselves further behind instead.
