I would say the real culprit is the dramatic decrease of teenagers using tobacco products. A quarter of high schoolers would use cigarettes regularly 20 years ago, but that number is now more like one in fifty.
It is well known that nicotine, as a stimulant, improves several ADHD symptoms (ex. https://www.sciencedirect.com/science/article/pii/S009130570...). It also improves negative symptoms in schizophrenia which is why they tend to smoke much more than the average population. Since smoking is very uncommon nowadays I feel like the people who would have self-medicated (i.e. a pack of cigs a day) in the past don't exist anymore. How many high schoolers have you met who smoke a pack of cigs?
