More War-on-Drugs Voodoo: Saliva Screening

by Crane-Station

Although touted as a useful tool to combat drunk and drugged driving, on-the-spot saliva drug screening is a war-on-drugs development that aims to target everyone, even the innocent. While the goal is to expand the saliva test to the workplace, the schools, and the family courts and programs, the roll-out will target random drivers. Rather than contribute to the decrease in impaired driving incidents, however, the practice will likely criminalize legitimate medication therapies by identifying miniscule and sub-therapeutic levels of some drugs.

This technology is being sprung onto the public ahead of any validation studies that connect a positive screening test in the field to actual impairment, but that has not stopped its premature use. House Bill 5385 in Michigan, for example, was set to force people to have this test, and this test exclusively, on demand. On Thursday, granting Michigan a temporary reprieve from this chicanery, state Rep. Mike Callton (R.MI) announced that the saliva test amendment would be dropped from the legislation based on the inaccuracy of the test. But it isn’t just about accuracy. It’s about targeting drivers randomly for non-impairment.

Drug testing ordinarily follows a two-pronged approach: a screen, and then a confirmation. Drug screening of body fluid is achieved by Enzyme Immunoassay (EIA)/Enzyme-Linked Immunosorbent Assay (ELISA), followed by confirmation, if the initial screen is positive. Confirmation takes longer and utilizes gas or liquid chromatography (typically), ie: GC/MS or LC/MS/MS, but it is more accurate and can serve to rule out false positive screens. There are limits of detection for each specified substance, and these are listed in each manufacturer’s FDA-regulated package insert; values below the detectable limits for commonly prescribed drugs are not of toxicological (or therapeutic) interest.

As the drug testing industry expands and takes on a life of its own that has little to do reality, the limits of detection are an issue. The saliva tests are not FDA approved, nor are there any clear methods or limits of detection anywhere, not to mention any connection to actual driving impairment or even any clear description of targeted parent drugs versus metabolites. There are no uniform guidelines for calibration, or specimen handling, and no algorithms exist to ensure chain of custody. The gaps between oral fluid detection and blood level confirmation and actual impairment are neatly filled in with “predictive toxicology.”

Furthermore, on Point of Care Testing (POC), even the Department of Transportation (NHTSA) explains that saliva tests are inaccurate:

THE FUTURE IN DETECTING DRUGS IN DRIVERS

Having an immediate drug test result obtained from a POCT-type test would permit the officer to confront the driver with the drug test result and make the DUID charge. At this time, however, only the urine based POCT technology appears to provide the accuracy and reliability required, and use of this technology is not yet widespread. With the advent of more “zero tolerance” laws, we may see the use of this technology grow. The development of sweat and oral fluid technology holds great promise for the field, but the most recent evaluations indicate that it may be a few more years before the desired sensitivity, specificity, accuracy, and reliability are attained.

That a drug test isn’t exactly proven, however, hasn’t stopped the forensics/police/prosecutor community in the past. Just a few years ago, a urine test to determine alcohol (EtG test) use was pimped as the gold standard. Many doctors, nurses and other professionals in supervised treatment programs as well as others who were on probation or parole supervision had to submit to this test, to determine their compliance in the supervised programs. Professional licences were revoked or people went to jail, for ‘non-compliance,’ based on the ‘gold standard’ urine alcohol test. The courts were sold.

But then, the test was deemed to be bogus.

SAMHSA has issued an Advisory that cautions licensure bodies, other monitoring organizations, and staff in criminal justice settings that a widely used test for alcohol consumption is “scientifically unsupportable” as the sole basis for legal or disciplinary action.

Unfortunately, that did not help some people, because the courts had decided that the test was reliable.

The urine alcohol thing was a miserable failure, but the forensics industry is pushing forward, undaunted. Now, there is a huge move afoot, essentially, to find anything in the blood, and prosecute accordingly. Namely, the various versions of synthetic cannabis are the target. The limits of detection for the various substances have not been worked out, and the protocols have not been worked out, and connection to driving impairment has not been worked out, but that’s okay because the passing public makes a pretty decent lab rat, and if any other molecules of any sort are detected along the way, those are thrown in as well.

The marketing ploy for the saliva test is, “It’s just like a portable breath test.” The potential is endless, especially given that most Americans take medicine for some reason. Literally everyone can go to jail. Workers, school kids, drivers, professionals. There’s just one thing though. The saliva spot test for a given machine make and model, if positive in the field, will be sent to one lab, who will do another screening. Not a confirmation. Just a ‘confirmatory’ screen. This is actually in the product insert for one of the machines, the Dreager 5000. Draeger covers its ass nicely by saying that the actual result must be confirmed in the lab:

CONFIRMATION ANALYSIS
Positive results can be confirmed with a second oral fluid sample via an independent, third-party laboratory analysis using the gold standard method
for evidential tests. Results are available online in a matter of days.

Also note that the product is for “law enforcement only,” and that there is little information available about the machine, because the process is “proprietary.” The lab in this instance that stands to gain a fortune by re-testing the saliva in the lab is NMS Labs.

As it turns out, the Director of Forensics for NMS Labs, a person named Barry Logan, is instrumental in working with the government, to push for random, no-reasonable suspicion traffic stops and mandatory random screening of not just illicit drugs but also things like common anti-depressants, anti-seizure drugs…These are to be tested with limits of detection that are sub-therapeutic. Dr. Logan and others in the law enforcement and crime lab community are pushing for per se laws on everything. To justify the new voodoo drug war expansion, the government recently funded a traffic study. Passing it off with the fatuous excuse that they were performing a “traffic study” to combat drunk and drugged driving, they sent off-duty cops into 60 cities in several states last last fall, to flag down random motorists and collect DNA and body fluids as well as personal histories.

This unethical experiment on motorists that left towns speechless, was based on some Guidelines for research on drugged driving. The guidelines were the handiwork of an ‘expert’ panel- Dr. Barry Logan of NMS Labs is on the toxicology section of the panel. The goal is new laws for random mandatory body fluid (ie, saliva) testing and per se laws on illicit as well as therapeutic medicines (and various over-the-counter medicines), regardless of impairment. This includes miniscule amounts of cannabis.

Issue 11. What are minimum analytes to be tested and maximum cut-off concentrations in urine? Urine specimens provide a basis for further investigations in blood of relevant drug classes. Detection limits should be as low as analytically feasible.

Note that they mention urine, but the guidelines suggest blood for study purposes, with saliva as well, even though saliva is iffy. In the end, if they call it “Science” and go with saliva for the new gold standard, people will be none the wiser, and it’ll be just like CSI.

By the way, there is also a push for alcohol at .01 detection limit and a .05 BAC limit for driving, so anyone who had a glass of wine in a restaurant would go to jail. Also, before Dr. Logan failed upward to work with the government on driving policy and oversee a lucrative, huge private for-profit lab, he left Washington State’s crime lab, pretty much resigned in disgrace, because the workers under his purview at that lab were falsifying calibration papers on…you guessed it- portable breath machines.

On Thursday, the BOJ released some new incarceration numbers. The US continues to incarcerate and prosecute more people than any other country in the world, by a substantial margin. There are also sickening, heartbreaking articles about the mentally ill incarcerated being locked in solitary and left there. Strip searches and forced body cavity searches are still common.

Even though a recent London study determined that the US war on drugs is a dreadful failure that has created immense damage, the war on some drugs that was always a war on some of the people is picking up steam. And it is fundamentally flawed throughout.

    Monday Night Open Thread

    We’re trying a new idea. Check it out.

  2. MKX says:

    Well, his circle of friends {patsies} just keeps getting smaller. And his hope for fame as a “hero” has vanished. So, being the con he is, maybe an about face will get him back in the limelight he craves.

    • Two sides to a story says:

      I feel the desperation sniffing closer.

      Here’s the video version of Taaffe’s confession.

  3. Two sides to a story says:

    Or, he just feels guilty. Taaffe wouldn’t be the first racist in America whose butt was chewed by karma and guilt.

    I wish Fogen had the balls to step out and say he was wrong to pursue with a loaded firearm and to create a deadly situation.

    It’s not too late to repent, Zim. Tick tock.

  4. MKX says:

    Another possibility is the Zpig reneged on something he promised Frank in exchange for loudly presenting the false meme about poor innocent George that so many swallowed hook, line and sinker.

    I mean George has a consistent pattern of using his “friends”.

    It would not surprise me if George’s using of people results in another shooting.

    Hell, Frank’s current demeaning of George is cause for a confrontation.

    Can Frank be called as a witness in the NBC case?

    I knew a racist from Florida and he slurred coons to sound like cones. All I know is that I don’t heat punks or goons, And cones make no sense at all. So that kind of narrows it down.

    And this idea that having a black friend makes one non racist is not true.

    A racist deems a black person as an animal less than human. And many a person, like a Bundy, can “like” or be “friends” with an animal.

    No, a racist makes a set of assumptions about another person based on that persons skin color. Sort of like:

    “He’s up to no good”

    “He’s {with a terror stricken voice} reaching in his waist”

    “He’s {with a terror stricken voice} looking at me”

    “the suspect”

    and last but not least:

    “Heeeeeeees Blaaaaaaack {with a fear ridden voice}”

  5. Two sides to a story says:

    Newsflash – Taaffe comes clean. http://www.mynews13.com/content/news/cfnews13/news/article.html/content/news/articles/cfn/2014/5/9/former_friend_suppor.html#.U22vULP310M.facebook

    I’ll believe we’re making progress when Jeralyn Merritt recants!

    Tick tock, Fogen.

    • MKX says:

      I am going to have to take back some of what I said about Taffe. Although he may have spouted repugnant views in the past, the Right Wing is going to crucify him, for what he just said. So he does have some guts. Pig, on the other hand, is still the lowest form of coward that let’s others take the fall for his acts.

  6. Malisha says:

    Just as possession of marijuana was used to segregate and enslave people of color, so will “saliva crimes” be used for that purpose, possibly differently but essentially “only more so.”

  7. MKX says:

    This fixation on a number in our society ignores a fundamental concept – the law of individual differences. Like it or not, there is a Bell Curve distribution for spatial aptitude and coordination amongst individuals. Therefore, it is entirely possible that individual A can have two drinks and drive safer than individual B. Let us see this for what it really is. Just another way to target {sample with bias} dirty f’in hippies and brown people in the right wings great war to make the USA clean {massive sarcasm}.

    And the law of individual differences also applies to addiction.

    There are individuals who can use drugs and be responsible and there are those who get hooked.

    A humane and sane drug policy would identify people who have addictive tendencies and get them help not punishment.

    I also note that the Reich Wing is fixated on race {differences amongst groups} differences, although these differences, if they exist, are so small as to fall below the noise floor of any decent control study and ignores the marked differences that exist amongst individuals within these arbitrary groups or, for that matter, society as a whole.

    And why is that?

    KKK junk science dies hard in the USA.

  8. Malisha says:

    Every single “random” DNA seizure victim should become a plaintiff in a civil rights action for violation of the Fourth Amendment.

    • bettykath says:

      The drivers who were stopped were given a paper to sign for consent that said they were participating voluntarily. Some read all the way to the fine print at the bottom to find that they had already tested the driver’s breath. No opportunity for them to give consent.

      Anyone want to bet that the dna doesn’t end up in a massive database for who-knows-what?

  9. masonblue says:

    There are many more. The totally fucked up, bizarre random DNA seizures happened in something like 60 cities.

  10. masonblue says:

    CS here. By the way, in case you did not know this, before Dr. Logan failed upward to work with the government on driving policy and oversee a lucrative, huge private for-profit lab, he left Washington State’s crime lab, pretty much resigned in disgrace, because the workers under his purview at that lab were falsifying calibration papers on…you guessed it- portable breath machines.

    The testing equipment is probably sold by a company whose ultimate owner is Halliburton. And this stuff is total junk science.

Here was his proposal to the government for the unbelievably unethical traffic pilot study that just occurred, where drivers in several states were flagged down and forced to give DNA, body fluids, detailed histories. People were told there was no way the information would be used. Bullshit- they have every intention of linking information to legal records:
