I agree that there is a mental health component there. I have ADHD as well and used to smoke. But I never flung it in the face of society by smoking 3 cigarettes at once in public as a "fuck you". There's a limit to that excuse. I know how ADHD works and it doesn't discount some amount of shame. This? This is shameful. ADHD people aren't completely unaware, I know it's hard, but it's also not a complete excuse to be this obtuse.
