Metabolic profile of N-ethylhexedrone, N-ethylpentedrone, and 4-chloromethcathinone in urine samples by UHPLC-QTOF-HRMS.

Forensic laboratories are constantly required to identify new drugs and their metabolites. N-ethylhexedrone (NEH, HEXEN), N-Ethylpentedrone (NEP), and 4-Chloromethcathinone (4-CMC, clephedrone) are synthetic substances structurally related to natural cathinone, alkaloid present in the leaves of the Catha edulis (Khat) plant. These synthetic cathinones (SC) are members of the heterogenous family of new psychoactive substances (NPS) that raised major concerns in scientific and forensic communities over the past years due to their widespread consumption.

GC-MS/MS Determination of Synthetic Cathinones: 4-chloromethcathinone, N-ethyl Pentedrone, and N-ethyl Hexedrone in Oral Fluid and Sweat of Consumers under Controlled Administration: Pilot Study.

This study presents a validated GC-MS/MS method for the detection and quantification of 4-chloromethcathinone or clephedrone (4-CMC), N-ethyl Pentedrone (NEP), and N-ethyl Hexedrone (NEH, also named HEXEN) in oral fluid and sweat and verifies its feasibility in determining human oral fluid concentrations and pharmacokinetics following the administration of 100 mg of 4-CMC orally and 30 mg of NEP and NEH intranasally. A total of 48 oral fluid and 12 sweat samples were collected from six consumers. After the addition of 5 μL of methylone-d and 200 μL of 0.

Pharmacological effects of methylone and MDMA in humans.

Methylone is one of the most common synthetic cathinones popularized as a substitute for 3,4-methylenedioxymethamphetamine (MDMA, midomafetamine) owing to its similar effects among users. Both psychostimulants exhibit similar chemistry (i.e.

Abuse Potential of Cathinones in Humans: A Systematic Review.

: Assessing the abuse potential of new substances with central nervous system activity is essential for preventing possible risks of misuse and addiction. The same methodology is recommended for the evaluation of the abuse potential of recreational drugs. This systematic review aims to assess the pharmacological effects related to the abuse potential and pharmacokinetics of cathinones, which are evaluated in both experimental and prospective observational studies in humans.

Interaction of Energy Drinks with Prescription Medication and Drugs of Abuse.

In recent years, the consumption of energy drinks (EDs) has become increasingly popular, especially among adolescents. Caffeine, a psychostimulant, is the main compound of EDs which also contain other substances with pharmacological effects. This review aims to compile current evidence concerning the potential interactions between EDs, medicines, and drugs of abuse as they are frequently consumed in combination.

Oral Administration of Cannabis and Δ-9-tetrahydrocannabinol (THC) Preparations: A Systematic Review.

Background And Objective: Changes in cannabis legalization regimes in several countries have influenced the diversification of cannabis use. There is an ever-increasing number of cannabis forms available, which are gaining popularity for both recreational and therapeutic use. From a therapeutic perspective, oral cannabis containing Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) is a promising route of administration but there is still little information about its pharmacokinetics (PK) effects in humans.

MDMA interactions with pharmaceuticals and drugs of abuse.

: MDMA (3,4-methylenedioxymethamphetamine), a synthetic ring-substituted amphetamine, has become one of the most widely used recreational psychostimulant drugs in the world. Among recreational ecstasy/MDMA users, polydrug use is a phenomenon whose common purpose is to experience the synergistic effect of the combined drugs, moderate MDMA effects, prevent potential toxicity, enhance a high or come down from a high from other drugs, or simply to treat existing medical conditions. Thus, MDMA-drug interactions (MDMA-DIs) lead to a higher risk of acute and life-threatening MDMA toxicity.

Cannabinoids: from pot to lab.

Cannabis is becoming increasingly present in our society. In recent years, the line between the natural (cannabis) and the synthetic (synthetic cannabinoids), the recreational (cannabis) and the medical (pharmaceutical cannabinoids and medical cannabis) has been crossed. In this paper we review some of the novel aspects of cannabis and cannabinoids in relation to their legal situation, changes in their composition and forms of cannabis use, the concept of medical cannabis, and synthetic cannabinoids as new psychoactive substances (NPS).

Results from screening immigrants of low-income countries: data from a public primary health care.

Background: A total of 3,132 immigrants from low- and middle-income countries were involved in a cross-sectional observational study to screen for infectious diseases among immigrants attending public primary health care (PHC) centers. The study was conducted to clarify the degree of demographic differences and risk predictors of these diseases.

Methods: Demographic and clinical variables, screening for infectious diseases [hepatitis B and C, human immunodeficiency virus infection, syphilis, and tuberculosis (TB)], and analytical data (anemia, hematuria, and liver function) were recorded from immigrants attending a public PHC unit in Barcelona.
