It's hard to tell but the numbers suggest it must be profitable. Why else would people keep installing so many machines? The machines have grown 2,100% over the last 5 years. They predict an annual cumulative average growth rate (CAGR) of 55% over the next 5 years which makes them one of the fastest growing industries in the market (by far). I plan on getting in the business and it would be great to get some feedback. I think testing the waters is the only way to really know.

As far as regulation, it is definitely wise to do proper research. I know where I am the one-way machines have the same regulation as a vending machine. Two-way are a little more complicated but not much more difficult.
