Is your neighborhood using? Researchers from Oregon State University and the University of Washington have devised technology that analyzes what’s been flushed down the toilet to measure how many speed freaks and coke heads you’ve got living down the street.

A report published in the  Dec. 15 edition of the American Chemical Society journal Environmental Science & Technology describes a new test that uses standard chemical analytical methods to look at  what  stuff makes its way through the municipal sewer systems to wastewater treatment plants. There, the test can measure levels of drugs including illegal substances like crystal methamphetamine.  Unlike previous methods, the technique does not require expensive and time-consuming sample preparation, making it a practical for comparing drug use in different regions.

The communal drug test was developed by looking at effluent from seven communities, identified in the report only by region (south, west, northeast and midwest). Maybe it is a good idea to take steps like reworking the formulation for Sudafed, which has been used as a  raw material for making crystal meth.  Overall, the study found the highest meth concentrations ever measured anywhere, based on samplings  at four plants located in the south and west of the U.S.  But, phew, coke in sewage was only comparable to European levels. Privacy from telemarketers is ensured by “no call” lists. Alas, a “no flush” list for your neighborhood is probably a non-starter.

Gary Stix, the neuroscience and psychology editor for Scientific American, edits and reports on emerging advances that have propelled brain science to the forefront of the biological sciences. Stix has edited or written cover stories, feature articles and news on diverse topics, ranging from what happens in the brain when a person is immersed in thought to the impact of brain implant technology that alleviates mood disorders like depression. Before taking over the neuroscience beat, Stix, as Scientific American's special projects editor, oversaw the magazine's annual single-topic special issues, conceiving of and producing issues on Einstein, Darwin, climate change and nanotechnology. One special issue he edited on the topic of time in all of its manifestations won a National Magazine Award. Stix is the author with his wife Miriam Lacob of a technology primer called Who Gives a Gigabyte: A Survival Guide to the Technologically Perplexed.
