Is there any research into nicotine’s role in assisting those with ADHD? It’s a stimulant as the article points out, which many ADHD medications are as well of course. I’m curious if nicotine was (perhaps unintentionally) used in the 20th century to help those with ADHD stay focused on tasks and if an increase of diagnosed ADHD cases in the 21st century stems from its declined use or if it’s entirely due to other factors such as generally being diagnosed to a greater degree.
