    PeakAL: Protons I Have Known and Loved — Fifty shades of grey-market spectra Stephen J. Chapman* and Arabo A. Avanes * Correspondence to: Isomer Design, 4103-210 Victoria St, Toronto, ON, M5B 2R3, Canada. E-mail: [email protected] 1H NMR spectra of 28 alleged psychedelic phenylethanamines from 15 grey-market internet vendors across North America and Europe were acquired and compared. Members from each of the principal phenylethanamine families were analyzed: eleven para- substituted 2,5-dimethoxyphenylethanamines (the 2C and 2C-T series); four para-substituted 3,5-dimethoxyphenylethanamines (mescaline analogues); two β-substituted phenylethanamines; and ten N-substituted phenylethanamines with a 2-methoxybenzyl (NBOMe), 2-hydroxybenzyl (NBOH), or 2,3-methylenedioxybenzyl (NBMD) amine moiety. 1H NMR spectra for some of these compounds have not been previously reported to our knowledge. Others have reported on the composition of “mystery pills,” single-dose formulations obtained from retail shops and websites. We believe this is the first published survey of bulk “research chemicals” marketed and sold as such. Only one analyte was unequivocally misrepresented. This collection of experimentally uniform spectra may help forensic and harm-reduction organizations identify these compounds, some of which appear only sporadically. The complete spectra are provided as supplementary data.[1] Keywords: 1H NMR, drug checking, grey markets, research chemicals, phenylethanamines, N-benzyl phenylethanamines, PiHKAL DOI: http://dx.doi.org/10.16889/isomerdesign-1 Published: 1 August 2015 Version: 1.03 “Once you get a serious spectrum collection, Nevertheless, an inherent weakness of grey markets is the the tendency is to push it as far as you can.”1 absence of regulatory oversight.

  • From Sacred Plants to Psychotherapy
    From Sacred Plants to Psychotherapy: The History and Re-Emergence of Psychedelics in Medicine By Dr. Ben Sessa ‘The rejection of any source of evidence is always treason to that ultimate rationalism which urges forward science and philosophy alike’ - Alfred North Whitehead Introduction: What exactly is it that fascinates people about the psychedelic drugs? And how can we best define them? 1. Most psychiatrists will define psychedelics as those drugs that cause an acute confusional state. They bring about profound alterations in consciousness and may induce perceptual distortions as part of an organic psychosis. 2. Another definition for these substances may come from the cross-cultural dimension. In this context psychedelic drugs may be recognised as ceremonial religious tools, used by some non-Western cultures in order to communicate with the spiritual world. 3. For many lay people the psychedelic drugs are little more than illegal and dangerous drugs of abuse – addictive compounds, not to be distinguished from cocaine and heroin, which are only understood to be destructive - the cause of an individual, if not society’s, destruction. 4. But two final definitions for psychedelic drugs – and those that I would like the reader to have considered by the end of this article – is that the class of drugs defined as psychedelic, can be: a) Useful and safe medical treatments. Tools that as adjuncts to psychotherapy can be used to alleviate the symptoms and course of many mental illnesses, and 1 b) Vital research tools with which to better our understanding of the brain and the nature of consciousness. Classifying psychedelic drugs: 1,2 The drugs that are often described as the ‘classical’ psychedelics include LSD-25 (Lysergic Diethylamide), Mescaline (3,4,5- trimethoxyphenylathylamine), Psilocybin (4-hydroxy-N,N-dimethyltryptamine) and DMT (dimethyltryptamine).

  • The Renaissance in Psychedelic Research: What Do Preclinical Models Have 2 to Offer
    CHAPTER The renaissance in psychedelic research: What do preclinical models have 2 to offer Kevin S. Murnane1 Department of Pharmaceutical Sciences, Mercer University College of Pharmacy, Mercer University Health Sciences Center, Atlanta, GA, United States 1Corresponding author: Tel.: +1-678-547-6290; Fax: +1-678-547-6423, e-mail address: [email protected] Abstract Human research with psychedelics is making groundbreaking discoveries. Psychedelics mod- ify enduring elements of personality and seemingly reduce anxiety, depression, and substance dependence in small but well-designed clinical studies. Psychedelics are advancing through pharmaceutical regulatory systems, and neuroimaging studies have related their extraordinary effects to select brain networks. This field is making significant basic science and translational discoveries, yet preclinical studies have lagged this renaissance in human psychedelic research. Preclinical studies have a lot to offer psychedelic research as they afford tight control of experimental parameters, subjects with documented drug histories, and the capacity to elucidate relevant signaling cascades as well as conduct invasive mechanistic studies of neurochemistry and neural circuits. Safety pharmacology, novel biomarkers, and pharmaco- kinetics can be assessed in disease state models to advance psychedelics toward clinical practice. This chapter documents the current status of psychedelic research, with the thematic argument that new preclinical studies would benefit this field. Keywords Psychedelic, Preclinical, Serotonin, Neuroimaging, Alcoholism, Anxiety, Depression, Substance dependence 1 INTRODUCTION The term psychedelic has come to be associated with a broad class of drugs with diverse chemical, pharmacological, and psychoactive effects.

  • Molecular Mechanisms of Addiction
    Molecular Mechanisms of Addiction Eric J. Nestler Nash Family Professor The Friedman Brain Institute Medical Model of Addiction • Pathophysiology - To identify changes that drugs produce in a vulnerable brain to cause addiction. • Individual Risk - To identify specific genes and non-genetic factors that determine an individual’s risk for (or resistance to) addiction. - About 50% of the risk for addiction is genetic. Only through an improved understanding of the biology of addiction will it be possible to develop better treatments and eventually cures and preventive measures. Scope of Drug Addiction • 25% of the U.S. population has a diagnosis of drug abuse or addiction. • 50% of U.S. high school graduates have tried an illegal drug; use of alcohol and tobacco is more common. • >$400 billion incurred annually in the U.S. by addiction: - Loss of life and productivity - Medical consequences (e.g., AIDS, lung cancer, cirrhosis) - Crime and law enforcement Diverse Chemical Substances Cause Addiction • Opiates (morphine, heroin, oxycontin, vicodin) • Cocaine • Amphetamine and like drugs (methamphetamine, methylphenidate) • MDMA (ecstasy) • PCP (phencyclidine or angel dust; also ketamine) • Marijuana (cannabinoids) • Tobacco (nicotine) • Alcohol (ethanol) • Sedative/hypnotics (barbiturates, benzodiazepines) Chemical Structures of Some Drugs of Abuse Cocaine Morphine Ethanol Nicotine ∆9-tetrahydrocannabinol Drugs of Abuse Use of % of US population as weekly users 100 25 50 75 0 Definition of Drug Addiction • Loss of control over drug use. • Compulsive drug seeking and drug taking despite horrendous adverse consequences. • Increased risk for relapse despite years of abstinence.

Narcotics WHAT ARE NARCOTICS? Also known as “opioids,” the term "narcotic" comes from the Greek word for “stupor” and originally referred to a variety of substances that dulled the senses and relieved pain. Though some people still refer to all drugs as “narcot- ics,” today “narcotic” refers to opium, opium derivatives, and their semi-synthetic substitutes. A more current term for these drugs, with less uncertainty regarding its meaning, is “opioid.” Examples include the illicit drug heroin and pharmaceutical drugs like OxyContin®, Vicodin®, codeine, morphine, methadone and fentanyl. WHAT IS THEIR ORIGIN? The poppy papaver somniferum is the source for all natural opioids, whereas synthetic opioids are made entirely in a lab and include meperidine, fentanyl, and methadone. Semi-synthetic opioids are synthesized from naturally occurring opium products, such as morphine and codeine, and include heroin, oxycodone, hydrocodone, and hydromorphone.
