I remember when mighty d block dropped and J hoods verse came up and he goes
"I came up as a young dude, hanging with the old cats
Couldn't cop crack, so I had to sell prozacs"
It frustrated the hell out of me because you can't get high off of Prozac. So who the hell was buying them? Dude was out there trying to be a legit "street pharmacist". For whatever reason the neighborhood folks Medicare wasn't covering their co pay for their depression medication, so J hood put on his lab coat and hit the corner.
If you scrape the coating off Prozac, it looks like crack.
That's probably what he meant.
I remember in high school people used to bag dirt and tell people it was heroin.
And when I went to jail, I heard a story of someone who got caught cutting up soap and selling it as crack.
