Opinions about drug legalization/decriminalization can differ based on whether a person has a personal history of substance use and as a function of demographic and ideological characteristics (such a religious or political preference). Legalization of drugs (e.g., cannabinoids) is the process of removing all legal prohibitions against it. Decriminalization of drugs (e.g., cannabinoids) means it would remain illegal, but the legal system would not prosecute a person for possession under a specified amount. Instead, the penalties would range from no penalties at all, civil fines, drug education, or drug treatment. Proponents of drug legalization argue that prohibition in general and the “War on Drugs” that began in the 1980′s, in particular, have created a black market for drugs, overloaded the criminal justice system, and failed to reduce the supply of drugs. On the other hand, the negative data of cannabinoids use far outweigh a few documented benefits for a limited set of medical indications, for which safe and effective alternative treatments are readily available. If there is any medical role for cannabinoid drugs, it lies with chemically defined compounds, not with unprocessed cannabis plant. On the other hand, the easy availability, cheapness, perceptive legality, and difficulty in detecting its presence with standard urine toxicologic tests, and similar factors probably contribute to the increased use, and popularity of synthetic cannabinoids. Although laws, and regulations concerning auditing of these substances have been implemented in many countries, production of new types of synthetic cannabinoids rapidly takes place.</div></div>","PeriodicalId":72899,"journal":{"name":"Emerging trends in drugs, addictions, and health","volume":"4 ","pages":"Article 100090"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143140972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 1,127 NPS have been reported worldwide as of 2022. The increasing chemical diversity and unprecedented substance numbers of NPS make this phenomenon even more difficult to detect, monitor and understand analytically. These synthetic substances containing more than one substance, pose a global threat for public health and cause challenges for analytical chemists, toxicologists, and clinicians due to their ever-changing chemical structure. Urine as the most common used matrix for analytical toxicology studies, is an invasive biological sample and allows a longer detection time for the parent drugs and their metabolites. Considering that the NPS recovered throughout Turkey are predominantly synthetic cannabinoids and that these substances are constantly changing, it is a necessity to develop an effective extraction method for urine which covers the currently consumed synthetic cannabinoids. In view of sample extraction techniques having a noteworthy contribution to analysis results, the aim of this study was to compare the efficiency of the two most widely used techniques, liquid-liquid (LLE) and solid-phase extraction (SPE) on the detection of NPS focusing mostly on synthetic cannabinoids. In this study, the comparison of extraction techniques was performed from urine by using liquid chromatography-tandem mass spectrometry (LC-MS/MS) system.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;In order to compare the efficiency of the extraction, different LLE and SPE procedures were evaluated in terms of recovery efficiency, accuracy, and precision. A 10-point calibration was prepared in methanol. The reference standards of synthetic cannabinoids and their metabolites, synthetic cathinones, a tryptamine, and a phencyclidine-type substance were spiked at 0.5 ng/L (low) and 5 ng/L (high) levels. Each sample was analyzed in triplicate using an LC-MS/MS system equipped with an electrospray ionization source operating in positive ion mode. The selected SPE procedure was applied to 20 authentic urine samples taken from volunteers.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;The optimized extraction method was validated in terms of selectivity, linearity, the limit of detection, the limit of quantification, accuracy, and precision. The linear range was achieved between 0.05-5 ng/L, and correlation coefficient values of analytes were ≥0.999. Accuracy and precision studies were satisfactory for most of the substances. Results showed that the developed extraction method was suitable not only for synthetic cannabinoids but also for synthetic cathinones, tryptamine (5-MeO-Mipt) and phencyclidine type substance (ketamine) as well.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;div&gt;NPS creates societal challenges that need to be addressed greatly due to its widespread use and the spee","PeriodicalId":72899,"journal":{"name":"Emerging trends in drugs, addictions, and health","volume":"4 ","pages":"Article 100100"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143141024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drug is extensively used as adjuvant therapy in treating neurotic pains, epilepsy, and seizures. The drug is available under brand names such as Neurontin, Gaborone, gralise, etc. It has been reported to be abused by opioid addicts in addition to its therapeutic use due to its anxiolytic and euphoric-like properties and easy availability in the market as a prescription drug. Scant research is available on the forensic examination of the drug under reference in body fluids. The present presents a method for the detection and determination of gabapentin from urine. The drug is not significantly metabolized in the human body and is excreted in the urine in its unchanged form allowing its qualitative and quantitative detection for forensic purposes.
