Substituted phenethylamines are a class of designer drugs that have recently emerged in the drug abuse market. Such substances remain legal to use, possess, and supply until these compounds become classified as scheduled. 2C-I-NBOMe or 25I-NBOMe is the N-benzyl-derivative of the iodo-substituted dimethoxy-phenethylamine (2C-I) that appeared recently in the(More)
AH-7921 is a structurally unique synthetic opioid analgesic that has recently entered the drug arena in Europe, the USA, and Japan.

Substituted phenethylamines are a class of designer drugs that hold a significant position in the drug abuse market. The most important substances within this class appear to be 4-bromo-2,5-dimethoxyphenethylamine (2C-B) and its novel derivative 2-(4-bromo-2,5-dimethoxyphenyl)-N-(2-methoxybenzyl)ethanamine (25B-NBOMe). Intoxications related to 2C-B use are(More)
"Krokodil" is the street name for the semi-synthetic opioid derivative desomorphine.

Sildenafil (SDL) is a phosphodiesterase type 5 inhibitor and it is approved for the treatment of erectile dysfunction and pulmonary hypertension. SDL is extensively metabolized to its pharmacologically active metabolite, desmethyl-sildenafil (DSDL). A sensitive and specific GC/MS method for the determination of SDL and DSDL in whole blood was developed and(More)
We present a validated gas chromatography-mass spectrometry method for the determination of Δ9-tetrahydrocannabinol and 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid in bile samples. The method includes protein precipitation with acetonitrile after enzymatic hydrolysis, and solid-phase extraction followed by silylation using(More)
Acetylfentanyl is a potent synthetic opioid analgesic that has been increasingly available in America, Europe, Japan, China, and Australia during the last years. It has no approved medical or veterinary use, but it is used illicitly around the world as a substitute of its controlled precursor, fentanyl, as well as of heroin or other related substances in(More)
