The Goes issues are generally irrelevant to recycled greywater. Recycling actually reduces transport to waterways and oceans, Soil applications allow soil bacteria to degrade many chemicals, about as well as sewage treatment plants. Recent pharmaceuticals are not more or less degradable then older ones. The most relevant question is whether certain substances would be taken up by food plants. Of course, waste recycling has been used for perhaps thousands of years, but it is probably better to avoid use on food plants, primarily because of possible pathogen recycling, if the wastewater or night soil has not been composted or sterilized. There are standards for that.
