You don’t know what the hell you are talking about. For people who actually have ADD, it is a very positive help for them.
It certainly helps me a great deal. I know a number of people who it helps a great deal. One guy makes over $700k/year and has a great life.
So au contraire, mon frere, I do know, up close and personal that Adderall is a life killer and needs to be taken off the market.
