Thanks, that confirms some things, especially why some take up smoking or now vaping. My own experience of smoking at age 10 (I can remember it vividly) suddenly being able to think in straight lines. I was not diagnosed until age 48 (Asperger's / combined ASD/ADHD).I'm going to keep trying to get people to listen, and try to get more help for people like yourself. The least they can do is tell you the truth, and maybe find out why you are drawn to use nicotine, or some other drug. It shouldn't be too much to ask.There is this if anyone ever asks you for evidence, might help?
