A study published in AACC’s Clinical Chemistry journal  shows that a novel drug test detects a new class of synthetic cannabinoids  called OXIZIDs. This test could enable drug enforcement agencies to identify  OXIZID users and could play a critical role in efforts to stop the spread of  these drugs.
OXIZIDs are one of the latest classes of synthetic  cannabinoids to enter the drug scene, and little is currently known about how  to detect them. A team of researchers from the National University of Singapore  therefore set out to develop a urine test for these drugs. Led by Eric Chun  Yong Chan, PhD, the team first incubated human liver microsomes with four  different OXIZIDs to get a preliminary idea of what metabolites are produced  when the human body breaks down these drugs. From this, the researchers  identified 42 to 51 metabolites for each of the OXIZIDs.
As a next step, Chan’s team tested four urine samples from  known OXIZID users for both the parent drugs and these metabolites. In the  samples, the researchers detected the parent OXIZIDs known as BZO-HEXOXIZID,  BZO-POXIZID, and 5F-BZO-POXIZID, along with their N-alkyl and  phenyl mono-hydroxylated metabolites. This shows that these compounds can be  used together in a urinary drug panel to conduct routine monitoring for OXIZID  abuse. Additionally, it’s important to note that the metabolites were present  in urine at higher concentrations than the parent drugs, showing the necessity  of including these metabolites in a drug test for OXIZIDs.
