Depends on age in many cases. At some point after puberty the Cokeish stuff begins acting normally and is no longer effective. Other than ritalin/amphetamines, they use the same drugs used to treat depression/manic depression/bipolar ect. Psychotropics.
It’s actually amphetamines.
As a person with ADD, I can assure you cocaine does not have any impact.
In fact, in college, the one time I tried cocaine everyone else got all worked up. Me...nothing at all.
I understand it gets diagnosed a lot. But, I wasn’t diagnosed until I was in my forties. The single drug literally changed my life. It saved my life.
