well, just an anecdote: back in 'the days' I used amphetamines (or whatever was supposed to be in the speed I bought from my dealer) for a couple of months, then quit it because it's disastrous for your body and switched to Ritalin for another couple of months because the amphetamine addiction was hard to cope with. And because Ritalin has very, very similar effects, including the side-effects like tremors and teeth grinding. So I was living the same sped up and fucked up life after all. Then I quit all of it which was followed by severe depression, while I never had such problems before that period of abuse. Depression, which afaik has been linked to dopamine functioning. Depression, which even years after the facts still sometimes wants to kick in. I'd almost say something is borken in my brain. Now I read an article saying use of MP might yield damage to dopamine neurons. Hey, sounds familiar. Now don't get me wrong, I'm not saying it's the same, but just using the fact that dosages in this study were way higher than what you normally use on your kids for instance means there's nothing to worry about seems a bit far fetched.
