LC separates the urine or blood sample and QTOF-MS provides high-resolution and accurate mass measurements for precise identification and structural elucidation of compounds. The LC-QTOF-MS method offers a more comprehensive and sensitive approach for drug detection, covering hundreds of recreational drugs, including NPS. Besides increasing the temperature to enlarge the drug aerolisation and bioavailability, one can elevate the flow rate of air through the e-cigarette and/or add a diluent . Of all e-cigarette users registered at this forum, 7.8 % vaped SCRAs . About 15 % of individuals registered at forums for drug users such as erowid.org who vaped cannabis have also vaped SRCAs. SCRAs belong, together with synthetic opioids, cathinones, amphetamines and hallucinogens to the new psychoactive substances (NPS) that are currently developed at high speed.

While the patient's symptoms strongly suggest the inhalation of ADB-BUTINACA, it is worth considering that these symptoms could also be attributed to nicotine exposure, as the symptoms partially overlap with known nicotine effect
THC, methamphetamine, SRCA, lysergic acid diethylamide (LSD), gamma-hydroxybutyrate (GHB) and ketamine are likely to become volatile under the temperature of current e-cigarettes, while crack cocaine is hard to vaporis
The presence of the product ion m/z 320, likely formed from a loss of carbon dioxide, indicated monohydroxylation at the tert-leucine in B8 (m/z 219), butyl side chain in B9 (m/z 145) and indazole moiety in B13 (m/z 161
Demographic and clinical features are recorded and blood and/or urine samples analysed using high-resolution accurate mass liquid chromatography-mass spectrometry. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper. Second, we could not
adb butinaca retrieve further detailed information about the e-cigarette that was used by the patient such as the label or the region of origin. Whether a recreational drug can be administered via vaping, depends on whether the drug becomes volatile under the evaporation temperature of the e-cigarette. Of these samples, 22 contained one or more SCRAs, THC was only detected in 11 samples, only one contained cannabidiol and 6 contained a mixture of THC and cannabidiol. There is difficulty in finding the right information about the NPS, defining their potency and confirmation of their existence in e-liquids or urine samples.

Each training session lasted a maximum of 10 min, and the rats could earn up to 20 food pellets. Thirty minutes prior to the training sessions, rats received an injection of either vehicle or Δ9-THC and were subsequently placed in the behavior-testing chambers, where food (45-mg food pellets; Bio-Serve, Frenchtown, NJ) was available as a reinforcer for every ten responses (FR10) on a designated injection appropriate lever. A houselight was centered over the hopper close to the ceiling and was illuminated only when the levers were active. Each dose range included doses that were without effect to those producing at least 50% depression compared to vehicle control. Twenty-four male Sprague-Dawley rats were obtained from Envigo (Houston, TX). Male ND4 Swiss–Webster mice were obtained from Envigo (Houston, TX) at approximately 8 weeks of age and maintained in the University of North Texas Health Science Center (UNTHSC) animal facility for two weeks prior to testin
Some mice showed abnormal behaviors (catalepsy, loss of traction, convulsion) right after the administration of the tested substances. The locomotor activity of the mice was measured 30 min and 2 hrs after the last substance administration. We also examined their neurotoxicity using brain samples through histopathological diagnose, especially in the nucleus accumbens core region. In histopathological analysis, neural cells of the animals treated with the high dose (5 mg/kg) of JWH-081 or JWH-210 showed distorted nuclei and nucleus membranes in the core shell of nucleus accumbens, suggesting neurotoxicity.

A limitation of this case report is that we did not have a urine sample available for additional NPS testing. Point-of-care DOA tests using urine to screen for misuse of multiple substances, regularly include cannabis, amphetamines, cocaine, opioids, benzodiazepines and methadone. THC, methamphetamine, SRCA, lysergic acid diethylamide (LSD), gamma-hydroxybutyrate (GHB) and ketamine are likely to become volatile under the temperature of current e-cigarettes, while crack cocaine is hard to vaporise. A systematic review including data of 114 patients of which the majority was intoxicated due to SCRA smoking revealed that 45 % of the patients who present at the ER after an intoxication due to SCRA smoking recovered within 24 hours .

Moreover, a study conducted in the United Kingdom investigated components of e-liquids in 112 samples originating from prisoners, teenagers and test purchases of commercially available e-cigarettes taken between 2014 and 2021 . This is the first case report that describes the toxicological symptoms of vaping ADB-BUTINACA. Results of the DOA test (including testing for amphetamines, methamphetamines, barbiturates, benzodiazepines, cocaine, methadone, opioids, cannabis, tricyclic antidepressants) were available within 30 minutes and were all negative. We report a case of an involuntary intoxication of the SCRA ADB-BUTINACA after vaping. There are several pitfalls in the detection of SCRA in samples taken from the patien
