Drug Testing Entire Cities at Once 562

Ellis D. Tripp writes "Researchers have developed a technique for determining what illicit drugs people might be consuming in a given area, by testing a sample from the local sewage treatment plant. As little as a teaspoonful of untreated wastewater can reveal drug use patterns in a given community. Obviously, any drugs found can't be tied to any specific user, but how much longer until the drug warriors want to deploy automatic sampling units farther upstream of the sewage treatment plant?" From the article: "one fairly affluent community scored low for illicit drugs except for cocaine. Cocaine and ecstasy tended to peak on weekends and drop on weekdays, she said, while methamphetamine and prescription drugs were steady throughout the week."

      Although some of most drugs will probably be excreted untransformed, what they're probably looking for in the waste is particular metabolites. So, by looking for both drug metabolites and the actual drug they can probably identify both consumers and flushers.

      Another interesting application, if they check further upstream, could be identifying areas containing drug labs. Looking for high concentrations of drugs and various manufacturing by-products in the waste stream could identify neighbourhoods containing labs. I used to be vaguely acquainted with a police forensic chemist who told me that they regularly laughed at some of the amphetamine labs they busted - in some cases, 60%-80% of their yield was going down the drain.

            Well actually adults should be responsible for their decisions. So if they are foolish enough to take them, then the drugs should be provided cheaply and upon a non profit basis (beyond charging tax specifically for rehabilitation purposes for those who request it), subject to of course those people who are under the influence of their drug of choice do not presenting a significant threat of harm to the general public.

            So if the users wish to keep themselves quietly locked away at their own expense, then they should live with the consequences of the choices they make as adults, after all, it really is only a problem for the rest of society because of the high cost of those drugs and the dangerous criminal element associated with distributing those substances, who, in fact have a significant financial interest in making sure those substances remain illegal.

            Whilst I am content to pay taxes for the medical treatment of a drug addicts, or to assist in rehabilitation services for them, having to pay the enormous cost of enforcing the illegality of those substances, or imprisoning the addicts, or the crimes that result because of the high cost of those substances and their addictive nature. As far as I am concerned those idiot wowsers are far more of a problem for me than the drug addicts, as the drug addicts are problem, which rather bluntly, eventually solves itself.

        Well, if I understand you correctly, I don't think you can really 'check upstream' for drug labs, because the drugs aren't flowing downhill. They enter the home from the highway and road system, not from the upstream water supply. If you have drug use in one area, I don't think you can extrapolate from water flow where exactly the drugs came from; you'd be better off looking at traffic pattern maps.

        You probably can identify areas with labs based on the methods they used to survey drug usage, but I don't

          You're probably correct on this, though I wouldn't be surprised to see someone argue it in court.

          Here's a workable Slashdot analogy for this: Just as one shouldn't link an IP address to a person (as the RIAA has tried to do), one shouldn't necessarily link what comes out of a household's sewage pipe to the person that lives there, either.

          My point being, just as someone can leech off an unsecured Wi-Fi in a home, someone from outside the household (i.e. visiting friend, relative) could conceivably use the bathroom.

          Then again, deployment of this type of surveilance would be kept plenty busy hunting down gross point sources like drug labs that they'd likely not bother to deal with individual drug use.

            That isn't what they would do. Obviously "We found some cocaine in the sewer coming from Bob's house so Bob must be have used and possessed cocaine" isn't going to what they go to court with.

            Instead they use that cocaine in the sewer as probable cause to get a search warrant to search the house. See all the trash searching leading to warrants in the past...

            And they wouldn't test all the houses, they'd test the ones they want to get a warrant for - for whatever other reason (resident has wrong skin colour, known drug users seem to visit often, etc, etc) that isn't good enough for a warrant by itself.

          The difference being that if you have something incriminating to get rid of, you don't have to throw it in your trash can and leave it on the curb. In essence, the laws on trash are basically that you don't need to be "authorized" in order to pick up garbage, recycle it, dispose of it, reuse it, compost it, etc.

          In contrast, people don't generally have an option of what to do with their urine and feces -- for most people, it's leaving the building in a wastewater pipe. And you do need the be licensed out the wazoo and have legal agreements with a homeowner and the state before you can just tap into wastewater outflow.

          I suspect it would come down to the "expectation of privacy" standard, and most people don't expect their wastewater can be seen by anyone before it is processed, but it's a normal expectation that anyone can peek in an unsecured garbage can.

        Economics is in the eyes of the beholder, at least in the War on Drugs. The economical way to deal with the problem would be to buy the coca and opium crops from their home countries, sell the pure finished products in government stores, and tax the hell out of it, making it still 1/100th the price of the illegal version for guaranteed quality. Instead, we pump billions into the prison-industrial complex, and poor people subsidize bribes to law enforcement, and people pay the price of overdoses and adulterated product. The expenditures to collect and test sewer water directly downstream of specific houses will be a nice windfall for public works unions, law enforcement, the legal profession, the test lab industry, and manufacturers of chemical analysis equipment. And of course, if it saves just one child from starting a meth habit, it's worth it, right?

      Not all drugs are actually as addictive as the authorities would like you to believe. I regularly take amphetamines -- on prescription, for ADD. I don't take them every day, and I don't abuse them by staying up for days at a time. Heroin and the other opiates are actually similar -- addictiveness varies person to person, and is dependent on dose, usage pattern, and most interestingly the environment the person is in. People in a happy environment can be regular recreational users without showing evidence of addiction. Perhaps the most interesting lab study of this was the Rat Park [wikipedia.org] study -- interestingly enough, when you stopped stuffing the lab rats in tiny boring cages and gave them an interesting environment to live in, they lost interest in the morphine. Even when the morphine water was sweetened. Perhaps even more interestingly, *some* of the rats *sometimes* used the morphine in the better environment -- a pattern we might call occasional recreational use in a person.

    I've got to say this is a very interesting idea. I've never heard anything like this.

    That said, I'd like to ask a question of /.ers. Many here are obviously against anything they see as an encroachment of their privacy. I agree with them to varying degrees. But in this case, where would you draw the line and why? Is there really a privacy concern at testing from the waste water from a whole city or region? But what if you are testing at the main sewer pipe that serves 20k people? How about 10k? What about a neighborhood of 500?

    As much as the "well they are breaking the law/what do you have to hide" appeals to me, I wouldn't support testing individual houses (or probably anything under a large chunk, say 10k).

    Why 10k? It is quite anonymous, yet would be small enough that it might provide some good relative data as to where certain drugs are more of a problem (especially in bigger cities, like 1 million+).

    Now once your waste water leaves your house and enters the pipes, it's no longer your property, right? Once garbage is placed out on the street (or in the garbage truck) it is no longer your property and the police can search it without a warrant right? This is the same thing isn't it? If not, when would waste water cease to be "yours"; considering that it is quickly mixed (permanently) with other waste water and unrecoverable.

    This is by no means new. The purpose of these tests is to track usage patterns. Such patterns are useful for understanding how and when drug usage trends spread from city to city, in addition to usage patterns over the course of a week or month. It is totally inconceivable that these tests could be used to identify drug users. Even if it were technologically possible, the cost would be prohibitive. If you could arrest every current drug user for possession, we would have many, many million more criminals than our jails could hold, not to mention the fact that jailing drug users is an excessively harmful way to deal with what is really a health problem.

    Now, water planners have to consider a much wider range of crap, from all the acetaminophen, birth control hormones, caffeine, and - yes - dope we're pissing away, as well as the usual collection of bacteria, viruses, organic matter, pez dispensers, and whatnot. It's not only that you don't want that stuff in the water supply, you don't want it collecting in the fish from the lake, Bambi's mom in the woods, or that water you merely boiled when out camping.

    So, an increasing number water districts have to collect this information anyway. All that Fields did was analyze a portion of the data more intently. If your jurisdiction plans to stick a sensor into your waste stream at a point immediately before it commingles with that from your neighbors, you'll know about it 'way ahead of time, because it would be a Major project. Frankly, most water districts are so busy trying to keep everything flowing in the right direction, they couldn't be less interested in wasting time checking on your THC-related metabolic byproducts.
