Or you can just account for not collecting waste of people that take drugs from a list ... you could have people that are part of the program and get some kind of crypto token for truning in their grade-A poo.

Well call them the Elite Shitters

Well I don't think you'd collect waste at the individual level, that seems absurdly arduous. Most developed nations already have an excellent pipeline (literally) for collecting and centralizing human waste. It would probably make more sense to collect it somewhere along the line at sewage treatment facilities. There would still be many other challenges with that.
