"Stimulants" refers to what a drug does to your heart and respiratory system - not necessarily what it does to your brain. I think that's a common misconception

"Stimulants" refers to what a drug does to your heart and respiratory system - not necessarily what it does to your brain. I think that's a common misconception. Pilots in the US Airforce, for example, have at one point (if not still) taken stimulants such as Adderall to remain awake, alert, calm and focused for long and taxing flights. I'm pretty sure that most of them didn't have "ADHD"
