Case report: Identification of AP-238 and 2-fluorodeschloroketamine in internet available powder samples sold as bucinnazine.

Novel synthetic opioids (NSOs) are a class of opioid agonists that include analogs of fentanyl and structurally distinct non-fentanyl compounds normally used as standalone products, heroin adulterants, or constituents of counterfeit pain pills. Most NSOs are not currently scheduled in the U.S.

DARK Classics in Chemical Neuroscience: Bucinnazine.

Bucinnazine (1-butyryl-4-cinnamylpiperazine) is a synthetic opioid recently discovered in heroin seized samples in the U.S and in Europe. It was first synthesized in the late 1960s and has been used for the treatment of cancer-associated chronic pain in China for many years.

DARK Classics in Chemical Neuroscience: Krokodil.

Krokodil is the street name for a homemade mixture that has been used as a cheap substitute for heroin. The main active substance in krokodil is desomorphine, an opioid that is 10 times more potent than morphine. Krokodil use began in Russia and Ukraine but has spread throughout several countries in Europe and North America.

Street-Like Synthesis of Krokodil Results in the Formation of an Enlarged Cluster of Known and New Morphinans.

"Krokodil" is the street name for a homemade injectable drug that has been used as a cheap substitute for heroin. Codeine is the opioid starting material for krokodil synthesis, and desomorphine is claimed to be the main opioid of krokodil and the main component responsible for its addictive and psychoactive characteristics. However, due to its peculiar manufacture, using cheap raw materials, krokodil is composed of a large and complex mixture of different substances.

Repeated subcutaneous administrations of krokodil causes skin necrosis and internal organs toxicity in Wistar rats: putative human implications.

Objective: "Krokodil" is the street name for an impure homemade drug mixture used as a cheap substitute for heroin, containing desomorphine as the main opioid. Abscesses, gangrene, thrombophlebitis, limb ulceration and amputations, jaw osteonecrosis, skin discoloration, ulcers, skin infections, and bleeding are some of the typical reported signs in humans. This study aimed to understand the toxicity of krokodil using Wistar male rats as experimental model.

Home Manufacture of Drugs: An Online Investigation and a Toxicological Reality Check of Online Discussions on Drug Chemistry.

Emerging trends in market dynamics and the use of new psychoactive substances are both a public health concern and a complex regulatory issue. One novel area of investigation is the availability of homemade opioids, amphetamines and dissociatives, and the potential fueling of interest in clandestine home manufacture of drugs via the Internet. We illustrate here how online communal folk pharmacology of homemade drugs on drug website forums may actually inform home manufacture practices or contribute to the reduction of harms associated with this practice.

Data analysis of "krokodil" samples obtained by street-like synthesis.

The data described in this work is related to be the subject of an article in the Forensic Science International, titled: "The harmful chemistry behind "krokodil": street-like synthesis and product analysis" (http://dx.doi.org/10.

The harmful chemistry behind "krokodil": Street-like synthesis and product analysis.

"Krokodil" is the street name for a drug, which has been attracting media and researchers attention due to its increasing spread and extreme toxicity. "Krokodil" is a homemade injectable mixture being used as a cheap substitute for heroin. Its use begun in Russia and Ukraine, but it is being spread throughout other countries.

The harmful chemistry behind krokodil (desomorphine) synthesis and mechanisms of toxicity.

"Krokodil" is the street name for the homemade injectable mixture that has been used as a cheap substitute for heroin. Its use begun in Russia and Ukraine and nowadays is being spread over several other countries. Desomorphine is the semi-synthetic opioid claimed to be the main component of krokodil and considered to be responsible for its psychoactive characteristics.
