Wastewater Analysis for Drug Abuse Evidence

A study in the journal Addiction shows that a viable system for measuring the consumption of illegal drugs in various communities is to analyze samples of untreated wastewater--which contains the leftovers. Steve Mirsky reports

[The following is an exact transcript of this podcast.]

If authorities wanted to determine how pervasive the problem of illicit drug use was in their communities, how could they do it? One cheap and easy way has just been tried experimentally in Oregon. Based on the principle that what goes in must come out, researchers measured the amounts and kinds of drugs that made their way through users to become included in untreated wastewater. This first-of-its-kind research is reported in the journal Addiction.

Ninety-six municipal water treatment facilities across Oregon volunteered for the study, which concentrated on finding evidence of the drugs meth, cocaine and ecstasy. All samples were collected on the same day, in areas that include about two-thirds of that state’s population.

Some findings: evidence for cocaine use was primarily in urban areas, almost nonexistent in rural regions; ecstasy use tended toward urban areas as well, and only turned up in about half of all communities; meth was everywhere. More important than those one-day snapshot findings, however, is that this methodology was proven viable, and could be used to track patterns of drug use in multiple regions over time.

    How soon is it that someone tries to use this technique to target individuals (or at least individual households)?

    Probably happened to individual housholds before they went public with the "Community" Testing.

    It's not like tapping a phone. There's no way the waste from an individual toilet can be targeted on its way to the sewer system.

    Dont ever think there is no way to do this. Jesus when are they going to quit spying on us?

    I don't think it's so much as a spying technique as it is just for stats. It would be nice to know what parts of the world are high on the scale for certain drug use.

    how much quantity is used which can be detected in waste water when it gets many many times diluted. moreover when consumed it is digested in body and might change its orignal form and very small quantity as residue may be going to sewer.Please clarify. k.k.gupta.

    And if someone hurriedly flushed a large cache of drugs down the toilet just before the police busted in? How much would that skew the results? After all, drugs flushed would presumably be drugs that went unused, right?
