It was just another sunny afternoon in the cruiser until you found yourself investigating a woman who is literally clawing at her own skin. On the ground you note a container with a white substance has fallen from her bag. Based on what you know, is this woman high on PCP? You observe her rapid eye movement and think twice about how to approach. Could it be she’s OD’d on meth? Maybe it’s neither. Bath salts have been on doctors’ and law enforcement’s radar for the past few years, but seem to be picking up pace. (Editor’s note: Read LET’s August 2011 “Drug Watch: Bath Salt Ban” at www.officer.com/10343027 for more facts pertaining to the drug.) Some say bath salts are similar to PCP with its volatile, violent symptoms. Unfortunately this drug (chemically, at least) is not that simple.

A slippery substance

While lawmakers are hard at work banning the salts, it’s not an easy job. Instead states are tackling the problem one ingredient at a time, whack-a-mole-style, chasing down new recipes and chemicals as quickly as they pop up. Today anyone can go into a head shop and purchase Ivory Wave, Red Dove or Blue Silk. Since its shape is always shifting, users’ volatile and often violent symptoms often depend on which “cocktail” they used.

“There’s very little that we actually know about how they interact on the brain,” says John Johnson, director of law enforcement programs at Thermo Scientific Portable Analytic Instruments. Johnson uses his background in biochemistry to build the right technology for specific applications in the field.

“What we do know,” says Johnson, “is mephedrone has been available in the UK for the many years, and seems to be the one most likely of causing an overdose.” He describes bath salts as “a combination of the worst of all drugs put together.” It’s difficult, then, for officers on the street to recognize someone using this substance specifically.

Street science

Agencies might not know they have a bath salt problem in their community simply because they can’t make these identifications. But now there’s a machine that does just that. Thermo Scientific Portable Analytical Instruments—the hazmat and bomb squad folks—recently launched a handheld laboratory analyzer that accurately tests liquid and solid samples for common narcotics. While it does not recognize organics like marijuana or mushrooms, TruNarc will identify substances such as cocaine, methamphetamine, MDMA and pharmaceuticals. The device uses Raman spectroscopy to develop a molecular fingerprint unique to each individual chemical. Spectroscopy has always been available in the lab setting, but now it’s literally on the street delivering easy-to-read results in seconds.

TruNarc can identify the MDPV as well as numerous other chemicals common in bath salts. This is important, because not only can law enforcement search for and find these active ingredients tout de suite, officers can also detect trends in over-the-counter drugs and keep a watchful eye on emerging “ingredient” make-up. Even though the DEA recently added three bath salt substances to their list, TruNarc’s currently got nine (not all illegal) identified bath salts in its capabilities.

Test-ingestion not required

Once a sample is selected, TruNarc generates a report and lists each chemical by name. Johnson says it’s common now to see bath salts being mixed with things like Advil PM, methamphetamine and ecstasy.

“Officers can then take that information and color-code it. Something that’s on the controlled substances list shows up as a red screen; something that’s maybe not on the controlled substances list but should be a concern shows up as green screen with a chemical name itself,” says Johnson. When a sample comes back showing a mixture of a bath salt that’s 95-percent MDPV, it will read “MDPV.” But if the mix includes mephedrone and pyrovalerone (not to be confused with the delicious sandwich cheese) it will indicate the combination.
