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.
There are no athiests in foxholes.
