  • Drugs of Abuseon September Archived 13-10048 No
    U.S. DEPARTMENT OF JUSTICE DRUG ENFORCEMENT ADMINISTRATION WWW.DEA.GOV 9, 2014 on September archived 13-10048 No. v. Stewart, in U.S. cited Drugs of2011 Abuse EDITION A DEA RESOURCE GUIDE V. 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. Teens can obtain narcotics from friends, family members, medicine cabinets, pharmacies, nursing 2014 homes, hospitals, hospices, doctors, and the Internet. 9, on September archived 13-10048 No. v. Stewart, in U.S. cited What are common street names? Street names for various narcotics/opioids include: ➔ Hillbilly Heroin, Lean or Purple Drank, OC, Ox, Oxy, Oxycotton, Sippin Syrup What are their forms? Narcotics/opioids come in various forms including: ➔ T ablets, capsules, skin patches, powder, chunks in varying colors (from white to shades of brown and black), liquid form for oral use and injection, syrups, suppositories, lollipops How are they abused? ➔ Narcotics/opioids can be swallowed, smoked, sniffed, or injected.

The alkaloids variation and its synthesis were studied in two varieties (NBRI-1, NBRI-2) of opium poppy {Papaver somniferum L.) on fresh weight basis of different plant parts at different growth periods. In cotyledon stage (3-4 days after germina- tion) only morphine was present. In roots of two leave stage, thebaine was observed beside morphine. At bud initiation stage morphine, codeine and thebaine were pre- sent during 1994-95 but in 1995-96 thebaine was absent. During bud dropping stage (pendulous bud) the sepals, petals and anthers had morphine. When pendulous bud straightened before flowering it has morphine, codeine and thebaine in all parts in- cluding ovary.

U.S. Department of Justice Drug Enforcement Administration Office of Intelligence Washington, DC 20537 (202) 307-8100 September 1992 ADMINISTRATOR·S MESSAGE Opium Poppy Cultivation and Heroin Processing in Southeast Asia reviews in detail several complex natural and chemical procedures linked with heroin production. It further explains how the opium poppy plant of Southeast Asia is grown and harvested, how the poppy's opium is chemically converted into morphine, and fmally. how that morphine is then refmed into "China White" heroin by Southeast Asian "cooks" and "chemists." The report will interest a wide audience: those studying "source country" issues, those determining opium poppy crop estimates in mainland Southeast Asia, and those monitoring and controlling the intemational import and export of chemicals. Opium Poppy Cultivation and Heroin Processing in Southeast Asia also presents the technical relationship between opium poppy cultivation in the Golden Triangle (the moun­ tainous region where Burma, Laos, and Thailand share common borders) and heroin production in the laboratories of Southeast Asia.

These findings have led to the development of biased opioid small molecule ago- G protein-coupled nists that do not recruit β-arrestin, activating only the canonical G protein pathway. Similar G receptor protein-biased small molecule opioids have been found to occur in nature, particularly within kratom, and opioids within salvia have served as a template for the synthesis of other G protein- biased opioids.

  • Role of Mu-Opioid Receptors in the Behavioral Effects of the Antidepressant
    Role of Mu-Opioid Receptors in the Behavioral Effects of the Antidepressant Tianeptine Jaena Han Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy under the Executive Committee of the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2021 © 2021 Jaena Han All Rights Reserved Abstract Role of Mu-Opioid Receptors in the Behavioral Effects of the Antidepressant Tianeptine Jaena Han For over half a century, the monoamine hypothesis has been the dominant theoretical framework guiding depression research and drug development. This hypothesis posits that depression arises from a deficiency in the monoaminergic neurotransmitters serotonin, norepinephrine, and possibly dopamine, and that antidepressants function by increasing extracellular availability of these monoamines in the brain, especially at the synaptic level. It is clear however, that the monoamine hypothesis cannot fully explain either the pathophysiology of depression nor the mechanisms of antidepressant action. Tianeptine is an atypical antidepressant used in Europe to treat patients who respond poorly to selective serotonin reuptake inhibitors (SSRIs). The recent discovery that tianeptine is a mu opioid receptor (MOR) and delta opioid receptor (DOR) agonist has provided a potential avenue for expanding our understanding of antidepressant treatment beyond the monoamine hypothesis. This dissertation aims to understand the neural circuits underlying tianeptine’s antidepressant effects. We first characterized the acute and chronic effects of tianeptine on depressive-like and other opioid-related behaviors in mice, and used genetic and pharmacological models to test whether these behavioral effects are mediated by MOR and/or DOR. We found that acute tianeptine administration produced an antidepressant-like reduction in immobility time in the forced swim test, as well as classic opioid-like effects including analgesia, hypophagia, hyperactivity, and conditioned place preference.

  • Production of Morphine and Variability of Significant Characters of Papaver Somniferum L
    Production of morphine and variability of significant characters of Papaver somniferum L. E. Matyášová1, J. Novák1, I. Stránská1, A. Hejtmánková2, M. Skalický1, K. Hejtmánková2, V. Hejnák1 1Department of Botany and Plant Physiology, Faculty of Agrobiology, Food and Natural Resources, Czech University of Life Sciences Prague, Prague, Czech Republic 2Department of Chemistry, Faculty of Agrobiology, Food and Natural Resources, Czech University of Life Sciences Prague, Prague, Czech Republic ABSTRACT Opium poppy (Papaver somniferum L.) is currently an important agricultural commodity, with the product being used in the food industry (seed) as well as in the pharmaceutical industry (morphine and other alkaloids). Intensive production of poppy leads to a specific direction of breeding with the aim to obtain highly productive cultivars of the so-called food industry or industrial type. The paper evaluates 57 genetic resources (mostly cultivars), compar- ing the groups of values representing the indicators of production-significant morphologic and agricultural charac- ters (capsule size; morphine content in poppy straw; weight of dry, empty capsule) and content of morphine in the poppy straw, in relation to the ideotype of poppy, which in these indicators represents 100% of the value. On aver- age lower values in the above indicators were achieved by cultivars with white-coloured seed, including morphine content; concrete data are specified in three cultivars with morphine content in the poppy straw above 0.40%. In blue-seed to grey-seed cultivars, except for the high-morphine cultivar Buddha (1.85% of morphine), we found only six materials with a minimum morphine content of 0.8% in the poppy straw (maximum of 0.92%).

The aims of this work were morphological and phytochemical characterisation. Altogether 35 at first to investigate the variability of morphological characters as morphological and agronomic characters were collected for all well as the variability of alkaloid content.
