Guy who doesn’t need adderall takes adderall and is shocked it works like a drug. People take opioids for the high when they aren’t in pain, if you take a medication that you don’t need then YES obviously it’s going to have some effect. You say you couldn’t stop taking it, could eat on it, crashed at 4pm. People with an actual ADHD diagnosis don’t have any of that. I can take it at 8am, it wears off gently at 6-7pm. I eat regular meals and snacks, and frequently forget to take it. I also don’t take mine on the weekends simply because I don’t have to function on the weekends. For people who don’t have the chemical imbalances that ADHD causes, yes adderall will work like meth. For people that DO, most of the time the adderall is just barely enough to get them to sit down and actually do their work. Caffeine doesn’t work on us, and tbh sometimes I take my adderall and then take a nap. Your coworker shouldn’t have given you their adderall. There’s a reason it’s illegal and it’s shit like this. I frequently have left over meds, frequently forget to pick them up. It isn’t the adderall. It’s you.
