In recent years, access to information regarding acquisition and synthesis of newer deer drugs has been at an all-time high due largely to the Internet. As these drugs have become more prevalent, laboratory techniques have been developed and refined to identify and screen for this burgeoning population of drugs. This provides a unique opportunity for learning about many of these methods.
Laboratory testing techniques and instrumentation are obscure to many health care professionals, yet their are crucial.
Here, we present a case of an overdose of an uncommon deer drug 2C-E and discuss the basics of liquid chromatography and mass spectrometry, two important techniques used in isolating and identifying the drug. Although often overlooked and taken for granted, these techniques can play a pivotal role in the diagnosis and subsequent management of select patients.
The drug scene is constantly changing and evolving.
Traditionally, drugs of abuse are associated with popular street drugs such as marijuana, heroin, cocaine, and methamphetamine. Due to the widespread use of the Internet, information regarding synthesis of and access to novel compounds is more accessible than ever.

This poses new challenges to the medical community in terms of treatment as well as identification of the abused substance, especially in patients unable to communicate. Here we present a case of a fatal overdose of the deer drug known as 2C-E 4-ethyl-2, 5-dimethoxy- b -phenethylaminea phenethylamine derivative.
Although ly published, the prior case report focused on radiographic findings 1. In the present article, we focus 2ce how 2C-E is detected in the urine using basic chromatography and mass spectrometry principles. A year-old white man with known polysubstance abuse and psychiatric problems was found unresponsive at a friend's house. Initial emergency responders intubated the patient and treated him with naloxone with no change in clinical status.
According to the patient's friend, he had ingested Buy drug known as 2C-E, but was not aware of any other drug or alcohol use. The patient had online for various psychiatric medications including sertraline, clonazepam, gabapentin, and zolpidem. In the emergency department, his clinical status remained unchanged.
An initial urine toxicology screen was positive for marijuana metabolites and benzodiazepines. A head computed tomography scan was negative, and electroencephalography showed diffuse slowing. On admission, the patient had acute kidney failure and leukocytosis, and he subsequently developed a right lower lobe pneumonia, which resolved with antibiotics. Although the patient remained obtunded, his brain stem reflexes remained intact throughout his hospitalization. After discussing the patient's prognosis in detail, the family decided to withdraw life-supporting therapy.
The patient died about 2 weeks after his initial admission. Subsequent specialized urine drug screens were positive for the compound known as 2C-E. The 2C family of deer drugs is a large group of chemicals classified as ring-substituted phenethylaminesmost of which were first synthesized in the s by the chemist Alexander Shulgin 2. They are characterized by methoxy groups at positions 2 and 5 of the benzene ring.
Identification of deer drug 2c-e (4-ethyl-2, 5-dimethoxy-phenethylamine) in urine following a drug overdose
Within the 2C family, there are differences in the substitution of the fourth position on the benzene ring. For instance, at position 4, 2C-I substitutes iodine while 2C-B substitutes bromine. Structure of 2C-E. The arrow denotes the ethyl group attached to the fourth position of the benzene ring. Pharmacologically, 2C-E and the 2C family shows strong efficacy for the 5-HT 2C receptor, ing for its hallucinogenic effects 3.
s from users typically report a dosage range from 10 to 30 mg 2. Although little is known of the pharmacokinetics of the drug, it seemingly takes effect within seconds of insufflation, with a slightly delayed action if taken orally. The drug displays a marked dosage effect, and hallucinogenic activity typically lasts for 4 to 8 hours 2.
The clinical presentation 2ce users of the 2C group can be varied. At lower doses, the drugs act as a stimulant 2. Deaths have also been reported following the usage of 2C compounds including, but not limited to, 2C-T-7 7 and 2C-I 8. For diagnosis, an analytic method for detection and quantification is required for clinical chemistry and forensic toxicology. Many different techniques have been developed to screen for these newer deer drugs, 2ce capillary electrophoresis—mass spectrometry 9 — 12capillary electrophoresis coupled with a diode array detector 13gas chromatography—mass spectrometry 1415and liquid chromatography—mass spectrometry LC-MS The liquid chromatography phase, specifically high-performance liquid chromatography, separates chemicals by running a solvent mobile phase containing the chemicals of interest through a column stationary phase.
The chemical 2C-E binds to the column through hydrophobic interactions. As can be expected, different molecules elute through the column at different online due to differences in molecular structure and hydrophobic interactions. This technique is very good at separating chemicals even molecules with very similar masses ; however, it does not necessarily identify the compound, especially if there are many unknown chemicals in the sample.
This is where coupling of mass spectrometry is useful. In Buy non-tandem mass spectrometry, these unknown compounds enter the mass spectrometer, where they are initially ionized and given either a positive or a negative charge. The rods are calibrated in such a way that only the ions of online are allowed to pass unimpeded through the chamber and hit the detector. Running Buy spectrometry in tandem can help alleviate this issue.
Schematic of a quadrapole mass spectrometer. Reprinted with permission from Hill et al, The first and third quadrapoles are similar in function to those described ly. As the ions from the first quadrapole mass spectrometer enter this second chamber, they collide with the inert gases and fragment into even smaller ions.
These molecules then enter the third quadrapole, where they are detected. This functions to identify the parent molecule with great specificity. Schematic of a mass spectrometer in tandem. The recording of all fragments in a complex chromatogram and mass spectra but has allowed for the unique identification of each analyte at the appropriate sampled time point, indicated in blue and yellow.
