ELI5: If cocaine is expensive, why is crack so cheap?

My best guess is that by smoking cocaine, you get more of the drug into your bloodstream quicker, therefore a smaller amount of crack gets you equally high.

cocaine is used to manufacture crack.  There is less cocaine per dose of crack than there is per dose of cocaine.  The process of making it into crack makes it much more potent so you can consume less for the same high.  This allows them to sell it cheaper.

One does not normally smoke cocaine.
