I don't see a great demand for invasive surgery, especially given the difficulty of finding a qualified physician who would be willing to risk his license in order to perform it.

Give people cheap and safe surgery or another means to achieve the same effect (e.g., crack cocaine) and I'm certain you'll find the demand.
