Humanity and biology in general is a precursor to addictive behavior. One of the major reasons people self-medicate, is because they think they are their thoughts. They indulge every whim and emotional impulse as if it is a command line directing their life.

That person is in college, and the social acceptance of taking adderall to succeed is scary. If you can handle a low dose, great, I'm all for practicality. But most can't and the idea that amphetamines can cure a lack of focus is pseudoscience.

What you are saying is often the cause of the problem, not the solution.
