More than doubling your revenues on an existing product is never easy. Doubling production won't do it, because those most willing to pay will be satiated and it won't command the same price. Also, cocaine involves more processing and coca plants grow more slowly and need more space than cannabis, so even doubling revenues isn't going to double profits. It also takes a good year before coca plants can be harvested - and retooling a supply chain can always be expensive. Meth might be easier, but still suffers from the same market depth issue, and still involves building out more infrastructure, which is still expensive. It's also likely to raise the costs of precursors, which will again limit profits.

I really don't see that any of these considerations are any different due to it being a black market - if you think they are, explain why.
