Actual fact: crack is manufactured from cocaine.
Google will tell you how to make it. I won't bother, as it's unnecessary for this conversation.
The secondary effect of the manufacturing process: the dealer ends up with product that can be more easily subdivided, and sold separately. So, instead of selling a gram for >$100, the dealer could sell a small amount of crack for $10 or less.
And on top of that, the markup on crack was more than the equivalent amount of cocaine -- meaning more profit.
(prices are approximate, as I don't know what the market prices were, or are. Not my thing)
Child, in a battle of wits, you are unarmed.
Goodbye, and good riddance.

Just as powdered cocaine is manufactured from cocaine.
