Detection of "smoke powder" etomidate and its metabolite etomidate acid in blood and urine by UHPLC-MS-MS: application in authentic cases.

Recently, etomidate has been widely used as an alternative in illicit drug market. It is usually added to regular cigarette tobacco (commonly known as "cigarette powder") or mixed in e-cigarette oil sold through the Internet, retail stores, or entertainment outlets and other channels. An ultra-high performance liquid chromatography tandem mass spectrometry method was developed to quantify etomidate and etomidate acid in human blood and urine. The limit of detection (LOD) of etomidate and etomidate acid in blood is 0.5 and 2 ng/mL, respectively, and the lower limit of quantification (LLOQ) is 1 and 5 ng/mL, respectively. The LOD of etomidate and etomidate acid in urine is 1 and 2 ng/mL, respectively, and the LLOQ is 2 and 5 ng/mL, respectively. The precision, accuracy, recoveries, and matrix effects of etomidate and etomidate acid determinations in blood and urine met the requirements for methodological validation. The method was successfully applied to the identification and quantification of etomidate and etomidate acid in blood and urine of 62 forensic cases. The concentration of etomidate ranged from 1.52 to 8.41 ng/mL (positive cases, n = 5) and the concentration of etomidate acid ranged from 2.76 to 112 ng/mL (positive cases, n = 5) in blood. The concentrations of etomidate and etomidate acid in urine samples were 2.64-79,300 ng/mL (positive cases, n = 59) and 6.11-518,000 ng/mL (positive cases, n = 60), respectively. Therefore, the concentration of etomidate in blood and urine is mostly higher than that of etomidate.

“Similar to Legal Companies”: Vendor Brands and Other Aspects of Marketing Communication in the Darknet Drug Trade

ABSTRACT The darknet or illicit online drug trade has expanded significantly in recent years. Vendors’ marketing communication strategies remain underexplored, however, as researchers focus on well-identified methods such as product quality, delivery times, or stealth shipping techniques. This study aims to show the multifaceted nature of sellers’ marketing practices on the dark web, including nonstandard approaches such as discounts, free samples, sales, contests, and lotteries. The article presents a case study of Cebulka, the largest Polish-language darknet market, using qualitative content analysis, natural language processing, descriptive statistics, and in-depth interviews. On Cebulka, vendors build relationships with buyers and maintain their trust through “marketing as promise management,” which includes feedback and review systems. The multi-method research approach reveals the nuanced nature of marketing on darknet platforms, drawing parallels and distinctions with traditional drug marketing. Additionally, this study contributes to understanding the darknet drug trade within the context of local markets, another underexplored topic.

Pyrrolo[2,3-D]Pyrimidines as EGFR and VEGFR Kinase Inhibitors: A Comprehensive SAR Review.

Tyrosine kinases are implicated in a wide array of cellular physiological processes, including cell signaling. The discovery of the BCR-ABL tyrosine kinase inhibitor imatinib and its FDA approval in 2001 paved the way for the development of small molecule chemical entities of diverse structural backgrounds as tyrosine kinase inhibitors for the treatment of various ailments. Two of the most prominent tyrosine kinases as drug targets are the epidermal growth factor receptor (EGFR) and the vascular endothelial growth factor receptor (VEGFR), as evidenced by the clinical success of their many inhibitors in the drug market. Among several other physiological roles, EGFR regulates epithelial tissue development and homeostasis, while VEGFR regulates tumor-induced angiogenesis. The pyrrolo[2,3-d]pyrimidine nucleus represents a deaza-isostere of adenine, the nitrogenous base of ATP. The recent introduction of many pyrrolo[2,3-d]pyrimidines to the drug market as tyrosine kinase inhibitors makes them a hot topic in the medicinal chemistry research area at the present time. This review article comprehensively sheds light on the structure-activity relationship (SAR) of pyrrolo[2,3-d]pyrimidines as EGFR and VEGFR tyrosine kinase inhibitors, aiming to provide help medicinal chemists in the design of future pyrrolopyrimidine kinase inhibitors.

Differences in heroin overdose risk associated with the unregulated drug market: Insights from a supervised injecting facility in Melbourne, Australia.

To determine the contribution that variation in the unregulated drug market has on the risk of heroin overdose across individuals with different levels of personal overdose risk. A retrospective cohort study of heroin injecting episodes and overdose cases were examined over a 12-month period between 30 June 2022 and 30 June 2023. The Medically Supervised Injecting Room in Melbourne, Australia. 1474 witnessed heroin overdose cases were examined amongst a cohort of 337 individuals who were predominantly male (n = 276, 81.7%) with a median age of 43.5years (interquartile range 37.25-49.00 years, range 20-75 years). The daily overdose rate was used to differentiate High and Low daily overdose risk categories. The number of overdose events that an individual experienced during the study period was used to differentiate people into Standard, Moderate and High personal overdose risk categories. Each overdose case was differentiated by the personal overdose risk of the individual who experienced the overdose, as well as the overdose risk of the day that overdose occurred. A stratified overdose risk profile was then derived across the nine different daily overdose risk and personal overdose risk categories. The rate of overdose approximately doubled on High overdose risk days compared with Standard overdose risk days, increasing by a factor of 2.11, 2.41 and 2.03 times for individuals in the Standard, Moderate and High personal overdose risk groups. Conversely, the rate of overdose was also substantially reduced on Low overdose risk days to a factor of 0.17, 0.28 and 0.20, respectively. Among heroin users in Melbourne, Australia, there is an approximately 10-times difference in the risk of overdose on some days compared with others, which appears to be attributable to the effects of the unregulated drug market and not the effects of variation in personal overdose risk of individuals.

The Frequency and Characteristics of Brokered Illegal Drug Sales: Reconceptualizing Illegal Drug Markets and Measuring Local Demand

Background Drug policies and interventions require an ongoing understanding of the local demand for illegal drugs. How illegal drugs are distributed to consumers is critical in the demand process. To overcome barriers to purchasing illegal drugs, people utilize their peers to purchase substances for them. These brokered drug sales allow buyers to leverage their peer networks to make purchases. For brokers, this form of exchange allows them to obtain drugs for free. This drug acquisition strategy is underappreciated in understanding how local drug market's function. Methods This paper presents findings from a brief survey on brokering collected from a random sample (N = 241) of active illegal drug injectors recruited from two syringe services programs in Ohio, USA. Results Findings indicate that 30-day and lifetime brokering behavior is common (71% and 90% respectively). Respondents who brokered in the last 30 days (n = 181) purchased drugs for an average of 7 people and from an average of 4 different sellers. Among this group, over 84% indicated that they used drugs with the person they brokered for, 49% reported often or always inflating the price to the buyer, and 27% indicated they removed some drug before returning to the buyer. Conclusion Measuring brokering offers new insight on the dynamics of drug markets, how they operate, and ways to measure their activity. The demand for illegal drugs incorporates the increased use of a drug, changes in the use of different drugs, and/or a novel drug being used. Accessing drugs via brokering accommodates these dynamics. By including brokering in drug market activity, the concept and scope of illegal drug markets transform into networks and not places.

Advances in Aerogels Formulations for Pulmonary Targeted Delivery of Therapeutic Agents: Safety, Efficacy and Regulatory Aspects.

Aerogels are the 3D network of organic, inorganic, composite, layered, or hybrid-type materials that are used to increase the solubility of Class 1 (low solubility and high permeability) and Class 4 (poor solubility and low permeability) molecules. This approach improves systemic drug absorption due to the alveoli's broad surface area, thin epithelial layer, and high vascularization. Local therapies are more effective and have fewer side effects than systemic distribution because inhalation treatment targets the specific location and raises drug concentration in the lungs. The present manuscript aims to explore various aspects of aerogel formulations for pulmonary targeted delivery of active pharmaceutical agents. The manuscript also discusses the safety, efficacy, and regulatory aspects of aerogel formulations. According to projections, the global respiratory drug market is growing 4-6% annually, with short-term development potential. The proliferation of literature on pulmonary medicine delivery, especially in recent years, shows increased interest. Aerogels come in various technologies and compositions, but any aerogel used in a biological system must be constructed of a material that is biocompatible and, ideally, biodegradable. Aerogels are made via "supercritical processing". After many liquid phase iterations using organic solvents, supercritical extraction, and drying are performed. Moreover, the sol-gel polymerization process makes inorganic aerogels from TMOS or TEOS, the less hazardous silane. The resulting aerogels were shown to be mostly loaded with pharmaceutically active chemicals, such as furosemide-sodium, penbutolol-hemisulfate, and methylprednisolone. For biotechnology, pharmaceutical sciences, biosensors, and diagnostics, these aerogels have mostly been researched. Although aerogels are made of many different materials and methods, any aerogel utilized in a biological system needs to be made of a substance that is both biocompatible and, preferably, biodegradable. In conclusion, aerogel-based pulmonary drug delivery systems can be used in biomedicine and non-biomedicine applications for improved sustainability, mechanical properties, biodegradability, and biocompatibility. This covers scaffolds, aerogels, and nanoparticles. Furthermore, biopolymers have been described, including cellulose nanocrystals (CNC) and MXenes. A safety regulatory database is necessary to offer direction on the commercialization potential of aerogelbased formulations. After that, enormous efforts are discovered to be performed to synthesize an effective aerogel, particularly to shorten the drying period, which ultimately modifies the efficacy. As a result, there is an urgent need to enhance the performance going forward.

Characterization of novel nitazene recreational drugs: Insights into their risk potential from in vitro µ-opioid receptor assays and in vivo behavioral studies in mice

2-Benzylbenzimidazole derivatives or ‘nitazenes’ are increasingly present on the recreational drug market. Here, we report the synthesis and pharmacological characterization of 15 structurally diverse nitazenes that might be predicted to emerge or grow in popularity. This work expands the existing knowledge about 2-benzylbenzimidazole structure-activity relationships (SARs), while also helping stakeholders (e.g., forensic toxicologists, clinicians, policymakers) in their risk assessment and preparedness for the potential next generation of nitazenes. In vitro µ-opioid receptor (MOR) affinity was determined via competition radioligand (3[H]DAMGO) binding assays in rat brain tissue. MOR activation (potency and efficacy) was studied by means of a cell-based β-arrestin 2 recruitment assay. For seven nitazenes, including etonitazene, opioid-like pharmacodynamic effects (antinociception, locomotor activity, body temperature changes) were evaluated after subcutaneous administration in male C57BL/6J mice. The results showed that all nitazenes bound to MOR with nanomolar affinities, and the functional potency of several of them was comparable to or exceeded that of fentanyl. In vivo, dose-dependent effects were observed for antinociception, locomotor activity, and body temperature changes in mice. SAR insights included the high opioid-like activity of methionitazene, iso-butonitazene, sec-butonitazene, and the etonitazene analogues 1-ethyl-pyrrolidinylmethyl N-desalkyl etonitazene and ethylene etonitazene. The most potent analogue of the panel across all functional assays was α’-methyl etonitazene. Taken together, through critical pharmacological evaluation, this work provides a framework for strengthened preparedness and risk assessments of current and future nitazenes that have the potential to cause harm to users.

As a technical tool to guide the optimal allocation of healthcare resources, pharmacoeconomic evaluation has been gradually applied to national healthcare decisions, including the adjustment of the National Reimbursement Drug List in China. With the acceleration of drug market approval and access to insurance coverage, the demand for pharmacoeconomic evaluation in healthcare decision-making is also increasing. Designing a pharmacoeconomic evaluation alongside clinical trials has become an important research direction and the source of evidence. In order to facilitate the standardization of this research field, the current consensus focuses on the topic of how to conduct a pharmacoeconomic evaluation alongside clinical trials from the Chinese healthcare system and decision-making context. The consensus group reconciled expert opinions and developed recommendations covering the entire process of study design, data collection and management, data analysis, and methods and results reporting. A total of 24 recommendations regarding to methodology and practice were developed from eighteen aspects including target population, selection of comparators, calculation of sample size, data collection of healthcare resource utilization, data collection of health-related quality of life, cost analysis, health outcome analysis, addressing the missing and censored data, etc., with the aim to provide reference for scholars and decision makers in this research filed.

Innovations in residential treatment that promote multi-drug addiction recovery

Abstract Background As the drug addiction crisis deepens in many countries across the globe, governments are rapidly expanding publicly funded treatment facilities. At the same time, the illicit drug market has evolved with many substances now containing multiple addictive drugs that complicate recovery. The evidence base for treatment remains primarily focused on single substances. The purpose of this study was to examine the lived experience of adults who attended in-patient treatment centres for multi-drug addiction in Canada. Methods This qualitative study was conducted in 2022 with 32 adults who voluntarily attended an in-patient treatment centre for drug addiction (44% female, 23-53 years). All had been addicted to multiple substances including opioids, crack and methamphetamines. Most (70%) were homeless before treatment. In 1-hour semi-structured interviews adults described the structures and programming that helped them recover in these facilities. Many tried multiple facilities and thus had a rich history of lived experience to draw from. Narrative inquiry was used to characterize qualitative themes across interviews using a phenomenological lens. Results Seven qualitative themes emerged from the data. Residential treatment centres that were effective at helping adults recover from multi-drug addiction: (1) provided flexible stays up to 100 days; (2) felt like a home not a prison; (3) permitted opioid replacement therapies; (4) provided a variety of recovery tools (e.g., cognitive behavioural therapy, Narcotics Anonymous, cultural supports); (5) helped adults reunite with family, find a safe place to stay, and find work before discharge; (6) provided transitional housing after discharge if needed; and (7) provided free long-term recovery support and check-ins after discharge. Conclusions The findings of this study highlight 7 actions that treatment facilities can adopt and test with their own clients in an effort to better support multi-drug addiction recovery. Key messages • A stronger evidence base is needed to inform in-patient multi-drug addiction treatment. • Findings underline 7 actions treatment facilities can take to promote multi-drug addiction recovery.

How promotion mix helps sustain brand sales during market transitions: insights from the pharmaceutical industry

Purpose Pharmaceutical marketers use detailing, sampling and direct-to-consumer advertising (DTCA) to promote a branded prescription drug (brand drug) to health-care professionals and consumers. These promotion mix elements help raise brand awareness, increase prescription likelihood and guard a product market against competing brand drugs. However, the extent to which these elements remain effective when a brand drug goes off patent and its marketing exclusivity expires, allowing low-price generics to enter the market, remains unclear. This study aims to explore the effectiveness of promotion mix elements before and after the market entry of a generic drug. Design/methodology/approach The authors collected and analyzed a panel data set of 41 brand drugs from 7 therapeutic classes between 2007 and 2014 (3,201 observations) using the two-stage control function approach to address potential endogeneity. Findings The effectiveness of promotion mix elements changes significantly, but not in a universally uniform way, during a market transition. Detailing and DTCA are increasingly effective after a brand drug’s generics enter the market. In contrast, sampling is more effective before the market transition. The positive effects of sampling on brand sales are stronger when the price of a brand drug is higher than the average price of its competing brands. Sampling also helps amplify the positive influences of detailing and DTCA on brand sales. Research limitations/implications This study shows that pharmaceutical promotion is not equally effective in the brand drug market with/without generic competitors. Detailing and DTCA are increasingly effective when generic competition intensifies. In contrast, the distribution of free drug samples is less effective after more generic drugs enter the market. Practical implications Incumbent brands’ promotion expenditures often drop dramatically when the expiration of their patents is near, a practice that likely continues after generics enter the market. Taking into consideration these industry norms and their findings, the authors suggest that promotional decisions during a market transition should not overly focus on cutting promotional expenditures across the board. Since a firm’s promotional expenditure tends to be expensive, factoring in information on the effectiveness of each promotion mix element helps marketers make well-informed strategic decisions on resource allocation during the transition from a market without generics to a market with generics. Originality/value Previous studies do not explicitly account for structural changes in the brand drug market over time. However, the expiration of patent and marketing exclusivity marks a transitional period in which a brand drug eventually competes with its generic counterparts. Given the criticality of such structural change, the authors examine brand drugs’ promotion effectiveness in the presence of their generic counterparts.

Exploring Human Misuse and Abuse of Veterinary Drugs: A Descriptive Pharmacovigilance Analysis Utilising the Food and Drug Administration’s Adverse Events Reporting System (FAERS)

Introduction: Evidence suggests an increasing misuse of veterinary medicines by humans. This study aims to analyse Adverse Events (AEs) associated with selected veterinary products using the Food and Drug Administration Adverse Events Reporting System (FAERS). Methods: A descriptive pharmacovigilance analysis was conducted on AEs related to 21 drugs approved for human and/or animal use. Results: A total of 38,756 AEs, including 9566 fatalities, were identified. The United States reported the highest number of cases (13,532), followed by Canada (2869) and the United Kingdom (1400). Among the eight drugs licenced exclusively for animals, levamisole, pentobarbital, and xylazine were most frequently reported. Reports predominantly involved males (57%) from the 18–64 age group, with incidents related mainly to overdose, dependence, and multi-agent toxicities. Unmasking techniques revealed ‘intentional overdose’ as the primary reaction. Polysubstance use was evident in 90% of the drugs, with benzodiazepines/Z-drugs and opioids as common co-used classes. Conclusions: Veterinary medications are increasingly infiltrating the illicit drug market due to their pharmacological properties. This trend highlights the need for heightened vigilance and awareness to prevent further public health risks associated with the adulteration of illicit substances with veterinary products like xylazine and pentobarbital.

Assessment of knowledge, attitude and practice of over-the-counter drugs and dietary supplements among non-healthcare college students in Chitradurga

Background: The market for OTC drugs and dietary supplements is rapidly growing. However, there exists a lack of adequate awareness among the general public regarding the advantages and potential drawbacks associated with these products, particularly among the younger generation, who heavily rely on the internet for information. Therefore, this study sought to assess the knowledge, attitude and practice of college students regarding OTC drugs and dietary supplements, including prevalence and associated factors. Methods: A prospective interventional study with 306 participants was conducted. Data were collected using a self-designed and pre-validated questionnaire and analysed using Statistical Package for the Social Sciences (SPSS) version 28. Descriptive and inferential (T-test) statistics were use. Results: The prevalence of usage of OTC drugs and DSs was found to be 98.4% and 61.4% respectively. Easy accessibility (42.2%), safe and well tolerable (32.5%) were the main factors that influenced them to turn to SM with OTC drugs. The respondent’s preference for DSs was primarily driven by their desire to maintain good health (33.6%). Internet (22.2%) and healthcare professionals (21.9%) were the two most reported sources that students relied on to obtain information about DSs. The result revealed poor knowledge and a positive attitude towards OTC drugs and DSs among all participants. Conclusions: A high prevalence of self-medication with OTC drugs and dietary supplements use was highlighted. Notable issues and improper practices were recognized. The findings indicate a need for education to enhance knowledge about OTC drugs and DSs and to encourage safe practices.

Drug utilization study of antidepressant drugs in psychiatric outdoor patients at a tertiary care hospital in Southern Rajasthan

Background: The World Health Organization (WHO) defines “Drug Utilization” as the marketing, distribution, prescription, and use of drugs in a society, with special emphasis on the resulting medical, social, and economic consequences. Antidepressants are used to treat depressive illnesses and anxiety disorders. However, these are also employed in the pharmacotherapy of several psychiatric disorders. Very few studies were found regarding the pattern of prescription of antidepressants in outdoor patients in southern Rajasthan. So, this study has been planned to learn about the prescription pattern of antidepressant drugs as per WHO Core Drugs Prescribing indicators at a tertiary care hospital in southern Rajasthan. Methods: A cross-sectional observational study was conducted among 375 patients by convenient sampling over one year duration, in the outdoor Department of Psychiatry at RNT Medical College, Udaipur, Rajasthan. Patient’s prescriptions were analyzed for drug utilisation pattern in OPD after relevant consent. All data was compiled in MS Excel and analyzed using statistical methods. Results: Out of 375 prescriptions analyzed, 48.8% were males and 51.2% were females. Most commonly, patients had a diagnosis of depressive disorder (42.93%), followed by bipolar affective disorder (14.4%). The most common drug class prescribed was SSRI (88.86%). Escitalopram (41.65%) was the most prescribed drug, followed by Sertraline (30.51%). Conclusions: Among the prescribed antidepressants SSRIs were the most common class of drug followed by TCA. Escitalopram was the most common drug to be prescribed followed by sertraline. More than half of the patients receiving antidepressants suffered from non-depressive disorders. Monotherapy was preferred over combination therapy. All patients were prescribed generic drugs.

An analysis of drug approvals in India over past 5 years

Background: Drug development is a tedious process and takes a long time for approval by regulatory authorities. With time, Indian authorities have revised rules and regulations for conducting clinical trials as well as for the marketing of drugs, impacting the number of drugs being approved. Method: The information about drug approvals from 2019–2023 was obtained from the CDSCO website. The single drug products were classified into 14 main anatomical therapeutic chemical (ATC) groups, while Fixed Dose Combinations (FDCs) were classified based on the system they act upon. Descriptive statistical analysis was done. The findings of our observational study were expressed as absolute numbers and percentages. Results: Total 362 drugs were approved. Out of these, 135 were single drug products, and the rest were FDCs. The highest & lowest number of drugs were approved in the year 2022 and 2019 respectively. Maximum single drug product approvals were seen in Category L-antineoplastic and immunomodulating agents, while maximum FDC approvals were for drugs acting on the endocrine system. Conclusion: There is a rising trend of approval for FDCs. The pattern of single drug products approval flattened over the years, coinciding with the implementation of new rules and regulations.

Beyond networks and institutions: Rethinking the role of organization in illicit drug market interaction

Social network and sociocultural approaches generally dominate current research on illicit drug markets. The main argument of these perspectives is that networks and social norms are more important elements than organization in drug markets. However, there is a need to understand aspects of interaction in drug markets that actors explicitly make decisions about – aspects that are the result of organization – alongside the emergent aspects emphasized in the social network and sociocultural approaches. In this conceptual article, we argue that partial organization theory offers a much-needed complement to existing approaches, and is useful in understanding how different groups, gangs, networks, states and market organizers in drug markets use decisions to organize their activities and the market as such.

Implementation of a community-based LC-UV drug checking service: promising preliminary findings on feasibility and validity

BackgroundThe increasing diversity of psychoactive substances on the unregulated drug market poses significant health, psychological, and social risks to people who use drugs (PWUD). To address these risks, various harm reduction (HR) policies have been implemented, including drug checking services (DCS). Many analytical methods are used for DCS. While qualitative methods (e.g., thin layer chromatography, spectroscopy) are easier to implement, they are not as accurate as quantitative methods (e.g., LC-UV, LC-MS). Some HR programmes have implemented high-performance liquid chromatography coupled with UV detection (LC-UV). This article presents the cross-validation of this quantitative method with a reference liquid chromatography coupled with high resolution mass spectrometry (LC-HRMS) method.MethodsDrug samples were provided by PWUD to a DCS called DrugLab in Marseille, France. The samples were weighed and prepared through dissolution in methanol, followed by ultrasonic bathing. Samples were analysed onsite using LC-UV analysis. They were then subsequently analysed with the reference LC-HRMS method. The LC-UV instrument in DrugLab was calibrated after being purchased; analysis of standard solutions was routinely performed once a month and after maintenance operations. For the LC-HRMS instrument, calibration and quality control procedures followed European Medicines Agency (EMA) guidelines. Statistical analyses were conducted including Spearman correlation tests using IBM® SPSS® Statistics version 20.ResultsA total of 102 samples representing different product classes and cutting agents were cross-validated. Differences between both analyses methods for each molecule analysed were ≤ 20%, with significant correlations between both methods’ results for most substances. Notably, LC-HRMS provided lower concentration values for cocaine and acetaminophen, whereas it provided higher values for other substances. Correlations were significant for cocaine, ketamine, MDMA, heroin, amphetamine, caffeine, acetaminophen, and levamisole.ConclusionsThis study demonstrates that the results provided by DrugLab were accurate and reliable, making LC-UV an adaptable, stable, and suitable analytical method for simple matrices like drugs in a DCS context. However, this cross validation does not guarantee accuracy over time. A proficiency test project in HR laboratories across France is currently under development in order to address potential drifts in LC-UV accuracy.

Double Designers: Detection of Bromazolam and Metonitazene in Postmortem Casework.

The identification of novel psychoactive substances (NPSs) in casework at the Los Angeles County Department of Medical Examiner (LACDME) is constantly evolving. The case detailed herein marks the first detection of metonitazene in forensic casework at the LACDME which occurred in August 2023. Furthermore, bromazolam was found in the decedent's system and both substances were identified in drug evidence collected at the death scene. No other drugs were detected and the manner and cause of death were determined as accidental due to effects of bromazolam and metonitazene. The concentrations detected were 1.6 ng/mL and 4.4 ng/mL of metonitazene in the jugular blood and femoral blood, respectively, and 93 ng/mL of bromazolam in the femoral blood. Constraints in screening techniques conducted by toxicology laboratories create challenges in which numerous NPSs available on the illicit drug market can go undetected. Even if labs detect an NPS in their screening methodology, confirmation methods might not cover every NPS, given the impracticality of labs keeping pace with validations as new NPSs emerge in casework. The significance of testing medical evidence collected at death scenes by drug chemistry analysis becomes crucial when initial toxicology results are negative. In cases where there is evidence of potential drug paraphernalia this is especially true as it can be pivotal in determining the cause and manner of death.
