  1. Hallucinogens(Psychedelics)

  2. Hallucinogens substances that alter sensory processing in the brain, causing perceptual disturbances, changes in thought processing, and depersonalization

  3. Modern day history of hallucinogens • The Native American Church • The American Indian Religious Freedom Act of 1978 • Timothy Leary and the League of Spiritual Discovery • The Psychedelic Experience

  4. The nature of hallucinogens • Many drugs can exert hallucinogenic effects • LSD types • Phenylethylamines • Anticholinergic agents

  5. Nature of hallucinogens Psychedelic Psychotogenic Psychotomimetic

  6. Sensory and psychological effects of hallucinogens • Altered senses • synesthesia • Loss of control • flashbacks • Self-reflection • “make conscious the unconscious” • Loss of identity and cosmic merging • “mystical-spiritual aspect of the drug experience”

  7. Traditional hallucinogens: LSD types agents • LSD (lysergic acid diethylamide), mescaline, psilocybin, dimethyltryptamine (DMT), and myristicin • These drugs cause predominantly psychedelic effects

  8. Of high school seniors sampled: 11.3% had used in 1975 8.6% has used in 1992 12.2% had used in 1999

  9. Traditional hallucinogens: LSD types agents • Physical properties of LSD • In pure form - colorless, odorless, tasteless • Street names - acid, blotter acid, microdot, white lightning

  10. Traditional Hallucinogens • Physiological effects • Massive increase in neural activity • Activates sympathetic nervous system (rise in body temp., heart rate, and blood pressure) • Parasympathetic nervous system (increase in salivation and nausea)

  11. Traditional hallucinogens: LSD types agents • About half of the substance is cleared from the body within 3 hours, and more than 90% is excreted within 24 hours • Effects of this hallucinogen can last 2-12 hours • Tolerance to the effects of LSD develops very quickly

  12. Other LSD types agents • Mescaline (Peyote) • Mescaline is the most active drug in peyote; it induces intensified perception of colors and euphoria • Effects include dilation of the pupils, increase in body temperature, anxiety, visual hallucinations, and alteration of body image, vomiting, muscular relaxation; in very high doses may cause death • Street samples are rarely authentic

  13. Other LSD types agents • Psilocybin - its principal source is the Psilocybe mexicana mushroom • It is not very common of the street • Hallucinogenic effects produced are quite similar to LSD • Cross tolerance among psilocybin, LSD, mescaline • Stimulates the autonomic nervous system, dilates the pupils, increases the body temperature

  14. Other LSD types agents • Dimethyltryptamine (DMT) • A short-acting hallucinogen • Found in seeds of certain leguminous trees and prepared synthetically • It is inhaled and similar action as psilocybin

  15. Other Hallucinogenic (LSD type) • Nutmeg • Myristica oil responsible for physical effects • High doses can be quite intoxicating • Can also cause unpleasant trips

  16. Phenylethylamine hallucinogens • The phenylethylamine drugs are chemically related to amphetamines. • They have varying degrees of hallucinogenic and CNS stimulant effects • Phenylethylamines that predominantly: • Release serotonin are dominated by their hallucinogenic action • Release dopamine are dominated by their stimulant effects

  17. Phenylethylamine hallucinogens • Dimthoxymethylamphetamine (DOM or STP) • “Designer” amphetamines • 3,4-Methylenedioxyamphetamine (MDA) • Methylenedioxymethamphetamine (MDMA)

  18. Anticholinergic hallucinogens • The anticholinergic hallucinogens include naturally occurring alkaloid substances that are present in plants and herbs • The potato family of plants contains most of these mind-altering drugs • 3 potent anticholingergic compounds • Scopolamine • Hyoscyamine • Atropine

  19. Anticholinergic hallucinogens • Atropa Belladonna: The Deadly Nightshade • Mandragora Officinarum: The Mandrake • Hyoscyamus Niger: Henbane • Datura Stramonium: Jimsonweed

  20. Other hallucinogens • Phencyclidine (PCP) • It was developed as an intravenous anesthetic, but found to have serious adverse side effects • It differs from the other traditional hallucinogens • It is a general anesthetic in high doses • It causes incredible strength and extreme violent behavior • Management of the severe psychological reactions requires drug therapy

  21. Other hallucinogens • Phencyclidine (PCP) physiological effects • Hallucinogenic effects, stimulation, depression, anesthesia, analgesia • Large doses can cause coma, convulsions, and death • PCP psychological effects • Feelings of strength, power, invulnerability; perceptual distortions, paranoia, violence, psychoses,

  22. Other hallucinogens: inhalants • The most commonly abused inhalants are volatile substances that can cause hallucinations, intoxication, and euphoria. • Volatile solvents • Anesthetics • Nitrites • Mild doses - mild stimulations, lack of motor control, dizziness, hallucinations • High doses - violent behavior, heart arrhythmia, unconsciousness, death22

  23. From the forest to the front lawn? • This lecture reviews basic information on most of the hallucinogen and dissociative intoxicants growing throughout the U.S. • Psychoactive composition, geographic distribution, and brief overview on preparation and/or intoxication will be reviewed

  24. Ephedra – Caffeine-like Stimulant

  25. The Ephedra Equation • Most “dietary supplements” marketed as psychoactive intoxicants contain ephedrine and/or caffeine from a variety of botanical sources. • In China, Ma Huang is used directly as a tea or compounded with other herbs. • Historically in the U.S., it was used as a stimulant tea: Mormon Tea, Brigham Tea, and other names. • Contains: ephedrine, pseudo-ephedrine, nor-ephedrine, methyl-ephedrine, tannins, saponin, and flavone

  26. Ephedra grows in the deserts of the Southwest

  27. Ephedra of the USE. trifurca, E. viridis, E. torreyana,E. nevadensis and E. californica • 100 gm dried ephedra could contain anywhere from 0 to 2.6 gm of ephedrine • Herbalists do offer pure extract preparations

  28. Psilocybe Mushrooms: Potent Hallucinogen • Psilocybin: 4-phosphoryloxy-N,N-DMT • Psilocin: 4-hydroxy-N,N-DMT • Psilocybe cubensis typically contains 1.6 mg psilocybin per gram of dried mushroom • 40 mcg/kg intoxicates • 3 to 4 hour duration

  29. Psilocybe Mushrooms • Small brown mushrooms that stain blue to the touch • Illicit cultivation but also foraged from temperate climates

  30. Psilocybe Mushrooms:Religious Use Religious use continues in Oaxaca, Mexico

  31. Psilocybin content

  32. Dimethyltryptamine – Potent Hallucinogen (DMT) • N,N-Dimethyltryptamine • 10 to 20 mg smoked : 15 minute intoxication • Approximately 100mg oral ingestion in presence of an MAOI: 3-4 hour intoxication • Many sources • Religious use of ayahuasca continues in Brazil; indigenous and “modern” religions: Santo Daime and Uniao do Vegetal. Both seek permission to use in the U.S.

  33. DMT…it’s as common as crabgrass… • “Canary” grass; Phalaris aquatica, P. arundinacea, P. canariensis, P. tuberosa • Desmanthus illinoensis; Prairie Bundleflower • Many other sources; mostly S. America.

  34. DMT content • Alkaloids reported as mg/100g raw dried plant +++++++++++++++++++++++++++++++ • P. tuberosa: DMT 100 mg+; 5-Me-DMT 22 mg+; 5-OH-DMT 5 mg • P. arundinacea DMT 60+ mg • Desmanthus illinoesis (root bark) DMT 340 mg • Psychotria viridis: DMT 200 mg

  36. Desmanthus illinoesis

  37. Monoamine Oxidase Inhibitors Sedative-hypnotic properties and possibly hallucinogenic/dissociative properties Sources: Peganum harmala, Passiflora spp., USED TO MAKE DMT ORALLY ACTIVE

  38. Peganum harmala

  39. Peganum harmala • Commonly called Syrian rue • Contains reversible MAOIs that may also be psychoactive (2 to 4% beta-carboline content). • Ayahuasca’s MAOI source only has 0.5% beta-carboline content. • Passiflora: approx. 1%

  40. Passiflora incarnata • Passion flower; fruit used in drinks; some herbal preparations as a “sedative”
