Keeping Up with Synthetic Cannabinoids Using Mass Spec

Facts about Synthetic Cannabinoids and why you need to pay attention to evolving science

  1. Synthetic Cannabinoids are easy to purchase as they are sold in many different forms online and at gas stations across the country
  2. Each batch varies as manufacturers can make chemical changes to the drug, eluding DEA regulation. “They are making something that’s not even illegal yet.”
  3. It’s the most used drug by high school students second only to marijuana

Mass spectrometry has proven an excellent tool for testing due to its flexibility to add new analytes as soon as new references become available. Even more compounds have been added to the DEA’s list of controlled substances.

Forensic screening methods for JWH-018 and JWH-073 and their metabolites (two of the main ingredients found in synthetic cannabinoids) using QTRAP technology have already been developed. In 2010, and this validated forensic screening method has been updated to detect JWH-081 and JWH-250 and their metabolites.  This is important news when it comes to drug enforcement since the DEA initially announced they would be controlling five synthetic cannabinoids (JWH-018, JWH-073, JWH-200, CP-47, and CP47-C8 homologue). Meanwhile, replacement compounds quickly emerged to include JWH- 081 and JWH-250.

You can read about the results in, “Detecting a New Wave of K2/Spice in Human Urine.” The main takeaways from the article are this:

  • Primary compounds are known to maintain a short half-life
  • A lack of standards and control samples in positive urine samples and metabolite identification becomes an intricate process
  • JWH-081 and JWH-250 were incubated in human liver microsomes in which hepatocytes and the in vitro metabolite pathway was identified for each compound
  • One injection and four cannabinoid injections scanned against the MS/MS library for a definite confirmation
  • Major metabolites identified

Telling the PFAS story with pine needles

As an ever-expanding group of chemicals, per- and polyfluoroalkyl substances (PFAS) require novel techniques to monitor their current and historical presence in the environment. Concerns over exposure to PFAS chemicals continue to grow, with some having known toxic characteristics and the potential effects of others remaining unknown.1 In addition, while PFAS are one of the most persistent synthetic chemicals to date, most of them hardly degrade in the environment.2 So, how long do traces of PFAS last in our environment? Two tools used to help answer this question are active samplers and passive samplers.

Back to the new basics: Part 3 | LC vs. LC-MS and what it means for your lab

In this final installment of our “Back to the new basics” series, we take one more look at analytical techniques and best practices in the lab, and opportunities to improve efficiency. Here, we explore the basic principles of high-performance liquid chromatography (LC) and liquid chromatography mass spectrometry (LC-MS), and how these techniques can affect a lab’s efficiency and productivity.

Meat vs plant based. What is the best option?

As we become more conscious about the planet, healthier lifestyles and our duty to protect the environment, attitudes and behaviours are shifting when it comes to food consumption.
