Which part? I agree that a lot of prescribed stimulant users are functional addicts. I also believe, as someone subscribed a stimulant for adhd who was productive beforehand, that patients and doctors know this and it is a calculated addiction.

The average methhead doesn’t take a micro dose just so they’re able to stay motivated and focused at work. If they did their wouldn’t be such a stigma. As an example the popular image of cocaine is a working man’s drug despite the fact it’s just as bad as meth when abused in large doses (induces psychosis, etc)
