Well, nicotine is actually a pretty good ADHD treatment option.
That's part of the reason why we see more (adult) ADHD these days: people used to smoke a lot. (Chain smoking plus guzzling black coffee used to be the stereotype for eg journalists or editors.)
So nobody strictly _needs_ to smoke, but it helps some.
(Before you go and light one up: smoking is one of the worst ways to get nicotine. Use a patch or lozenge or vape instead.)
