Testing for Many Designer Drugs At Once 281

LilaG writes "Drug tests spot banned substances based on their chemical structures, but a new breed of narcotics is designed to evade such tests. These synthetic marijuana drugs, found in 'herbal incense,' are mere chemical tweaks of each other, allowing them to escape detection each time researchers develop a new test for one of the compounds. Now chemists have developed a method that can screen for multiple designer drugs at once, without knowing their structures. The test may help law enforcement crack down on the substances. The researchers used a technique called 'mass defect filtering,' which can detect related compounds all at once. That's because related compounds have almost equal numbers to the right of the decimal point in their molecular masses. The researchers tested their technique on 32 herbal products ... They found that every product contained one or more synthetic cannabinoid; all told, they identified nine different compounds in them — two illegal ones and seven that are not regulated. The original paper appears (behind a paywall) in Analytical Chemistry." From the article: "The research is timely, too. 'Many drugs of abuse in the Olympics are designer drugs,' he [Gary Siuzdak] says, in the steroid family. Grabenauer plans to extend her method to other designer drug families."

      Until we apply a modicum of science to determining what vectors cause drug abuse in society, all we're doing is inventing new ways to fill prisons.

      There are a lot of "for profit" prisons being run by corporations. So generating more inmates may be a goal. More inmates mean more revenues for those corporations.

      And this is an easy way for politicians to appear "tough on crime" when they need election points.

      the 'war on drugs' is such an abject failure

      That depends on your definition of "success." Since its inception, there have been the following goals in the war on drugs:

      1. Harassing and arresting black people, especially black men. As far back as the debate on cocaine prohibition (yes, this was once debated), there were people, especially police officers, warning of the dangers of black men using drugs. Black men on cocaine were unstoppable monsters, and cops had no choice but to upgrade the caliber of their guns to fight them. Black men who smoked marijuana were incited to play jazz music, and white women who smoked marijuana would want to have sex with black men. Black men who use PCP will go crazy. Black people will go nuts over crack cocaine.
      2. Increasing police power. Related to the above, since we obviously need more police officers in black neighborhoods to crack down on dangerous black drug users. We also need cops attacking hippies and anti-war protesters. We need cops who carry assault rifles and grenades to fight the drug dealers (did I mention that they are black too? That's the message that the mainstream media sends.). The cops also need the power to declare drugs to be illegal, without consulting congress. The cops also need to be allowed to recycle seized assets from drug raids into their budgets. They need expanded surveillance capabilities.
      3. Corporate profits. Hemp fibers compete with synthetics. Alcohol, tobacco, and coffee companies have to compete with all those other recreational drugs, so let's make them illegal. Pharmaceutical companies get to inflate their profits by ensuring that only they legally are allowed to market entire classes of drugs (opiates, amphetamines, etc.). Firearms companies, law enforcement equipment makers, and so forth have seen big profits from the drug war. Let's not forget the private prison operators, a relatively new trend but an important one -- big profits come from big prison populations.

      Notice something missing from that list? Public health and safety. That's at the bottom of the priorities list in the war on drugs, because the war on drugs never had anything to do with health or safety.

    Just like when we had prohibition of alcohol, people were going blind from stills, refusing to regulate pot means they can make poisonous alternatives. I've heard of people getting real sick and permanently maimed off of designer drugs. The worst that can happen with pot is that you try and drive somewhere intoxicated. Pot doesn't even cause lung cancer like cigarettes(You can google many mainstream scientific studies).

    Legalization of pot would harm gangs who sell pot in addition to removing pot from being a gateway drug. Since people would no longer go to underground dealers for pot, they would no longer have access to the other underground connections.

    Let people smoke, shoot, drink, or otherwise ingest anything they want. Tax drugs, use part of the tax to pay for the societal costs of drug abuse, and go from there.

    Intoxication should be considered an aggravating factor in any crime, and should be made a crime in and of itself in certain situations (see driving under the influence).

    Making better tests is interesting in an academic way, and possibly useful for certain professions where sobriety is absolutely essential (law enforcement, for one example), but honestly, who gives a fuck for most anything else? If drug use affects your work you'll get fired in time anyway, and if you do harm to another person while high you're screwed anyway.

    I'm saying this as someone who works in public health - the damage done by this kind of prohibition VASTLY outweighs the societal benefit of restricting drug use. There's absolutely no question about it.
