I always assumed this was related to me getting easily hooked on anything (cigarettes and booze). I never touched things like heroine, coke, or meth since I knew my life would be over. I haven't had ADHD meds in ages because it used to basically take 6-7 hours once a month to go get them and get home. Now, Japan has a shortage of them and I don't even know where I would go to get them in my super-countryside area off hand.
