This is just plain wrong. People with ADHD are much more likely to develop addiction than people who don't. Most of the addicts I know, including myself, have it.
My experience is the opposite. I don't get addicted. Obsessed with a topic for a while? Sure! Compulsively repeating some behaviors, like checking HN? That's me! But once I get distracted by something interesting, it's like those never existed. They just lose their appeal.
ADHD is a pretty broad brush. While I’ve no doubt that some instances fuel a predisposition for addiction, I’ve seen exactly the opposite tendencies exhibited also.
I'm not saying there aren't people with ADHD who don't get addicted, but the statistics are unambiguous. Just google ADHD and addiction and you'll find plenty of studies.
9% of men without ADHD and 5% of women without ADHD
Fair enough, more than double. However, not the majority of the people with ADHD, so it could still be a ADHD-relates boredom problem and less a typical addiction issue. (Which doesn't make the results less dangerous, but the mechanisms that cause it different)
