If crack cocaine requires powder cocaine to make it, why is it cheaper?

Published May 16, 2010

I read that in order to produce crack cocaine, you need powder cocaine. I also read that crack cocaine is cheaper than powder cocaine.
How do you make money of it?
So I have a very simple business question. Why would someone buy powder cocaine, spend the time to cook it and make crack, and then sell it for less than they bought the ingredients for?
