  1. Hallucinogens By Kasey Andrews Kelly McDowell

  2. Statistics • 1965-1971: Hallucinogen use rose tenfold from 90,000 to 900,000 new users. • 1990-2000: Use again rose, nearly 3 fold from 600,000 to 1.5 million new users. • 2001-2002:LSD use decreased dramatically while MDMA and others rose.

  3. Definitions “Substances that create gross distortions in perception without causing loss of consciousness when administered in low doses.” “Substances that alter sensory processing in the brain, causing perceptual disturbances, changes in thought processing, and depersonalization.”

  4. Hallucinogens also called… • Psychedelics:substances that expand or heighten perception and consciousness. • Psychotomimetic:substances that mimic psychosis. • Psychotogenic:substances that produce psychosis.

  5. Hallucinogens … • Are found naturally in plants and can be produced synthetically. • Are used by Native American tribes for use during religious ceremonies. • Resemble 1 of 4 neurotransmitters • Acetylcholine • Catecholamines (Norepinephrine & Dopamine) • Serotonin

  6. Alterations in time and space perception Changes in self-awareness Increase sensitivity to textures, shapes, tastes, and sounds Visual disturbances (i.e. flashes of light or kaleidoscope-like patterns) Hallucinations Feelings of enlightenment or spiritual awakening Common Hallucinogenic Effects

  7. 4 Categories of Hallucinogens Anticholinergic Catecholamine-like Serotonin-like Psychedelic Anesthetics

  8. AnticholinergicHallucinogens

  9. Attach to Acetylcholine receptors and block the site so Acetylcholine cannot attach. • Impairs learning and memory as result • Found in Belladonna, Nightshade, Jimsonweed, and Mandrake plants. • Effects: Dry mouth, decreased sweating, dry skin, increased body temperature, blurred vision, increased heart rate, dilated pupils, drowsiness, decreased attention. @ High Doses = Hallucinations, paralysis of respiratory system, coma, and death. • Examples: Scopolamine, Mandrake, Hyoscine, Hyoscyamine, and Atropine.

  10. Scopolamine • used as poison and aphrodisiac in Renaissance Times. • Contained in Datura plant. Mixed with drinks to create a stupor in wives of chiefs or warriors before they were buried alive. • Mandrake • used to treat anxiety and acute pain. datura

  11. Catecholamine-LikeHallucinogens

  12. Also called Phenethylamine Psychedelics • Structurally similar to Catecholamines (Norepinephrine & Dopamine) and Amphetamines. • Explains why these drugs have stimulant and hallucinogenic effects. • Are mixed Dopamine and Serotonin agonists.

  13. EXAMPLES:MescalineMyristinElemicinSynthetic Amphetamine Derivatives

  14. Myristin & Elemicin • Myristin: found in nutmeg • Elemicin: found in mace • Has similar structure as Mescaline • Blocks release of serotonin in brain neurons. • 5-15 g. (approximately 2 tablespoons) in tea will produce confusion, disorientation, depersonalization, and feelings of unreality. • Side Effects: vomiting, nausea, agitation, dry mouth, rapid heart beat, and tremors. • Negative effects can last up to 12 hours.

  15. Synthetic Amphetamine Derivatives • DOM (dimethoxymethylamphetamine) • MDA (Methylenedioxyamphetamine) • TMA (trimethoxyamphetamine) • DMA (dimethoxymethylamphetamine) • MDE (methylenedioxyethylamphetamine) • MDMA (methylenedioymethamphetamine) • PMA (paramethoxyamphetamine)

  16. Cause increase of serotonin in synaptic cleft, & block the reuptake of it from cleft. = same for Dopamine • Increased Serotonin effects sensory information reception, and causes changes in sleep patterns and emotions.

  17. DOM • 1-6 mg doses produce euphoria and hallucinations for 6-8 hours in duration. • Hallucinogenic effects overpower the amphetamine effects. (is stimulant at low doses and hallucinogen at high doses) • At Toxic doses can produce tremors, convulsions, and death.

  18. MDA • Metabolite of MDMA • Synthesized in 1910 • Schedule I Drug in 1970 • Used to decrease appetite. • Called “Love Drug” because it heightens tactile sensations. • Causes increased release of Serotonin, Dopamine, and Norepinephrine. • Effect: dilation of pupils, tightening of jaw, grinding of teeth, and physical exhaustion that can last for 2 days. • High Doses: (100-150 mg) convulsions and death.

  19. MDMA • Street Names: Adam, Ecstasy, X, E, XTC, Blue Kisses, E bombs, Happy Pill, Hug Drug, Smurfs, Wafers, & others • More psychedelic than MDA • Synthesized in 1912 • Schedule 1 Drug in 1985 • Effects similar to MDA

  20. MDMA Combos • Candy Flipping = LSD + MDMA • Diamonds = Amphetamines + MDMA • Disco Biscuits = Depressants + MDMA • Flower Flipping = Mushrooms + MDMA • H-Bomb = Heroin + MDMA • Gum = Opium + MDMA • Kitty Flipping = Ketamine + MDMA • Sextasy = Viagra + MDMA

  21. Pharmacokinetics: • orally, injected, or snorted. • Effects last 3-6 hours • Dose is 1-2 tablets (60-120 mg each) • Readily absorbed in GI tract • Pharmacodynamics: • Increases levels of Norepinephrine, dopamine, & serotonin released.

  22. MDMA Effects • Hallucinogenic Effects: distortions in time & perception. • Stimulant Effects: Euphoria & hyperactivity, increase blood pressure & heart rate

  23. MDMA…The Negative Effects • Psychological: depression, severe anxiety, paranoia, and sleep disturbances. • Physical: muscle tension, teeth clenching, nausea, blurred vision, rapid eye movements, chills, & faintness. • High doses: sharp increase in body temperature, muscle breakdown, and kidney & cardiovascular system failure. • These effect also happen at low doses in combination with intense exercise or acitivity. • Long-Term: liver damage & brain damage. • Brain damage due to destruction of serotonin producing neurons = therefore problems regulating mood, pain, sleep, and aggression can result.

  24. MDMA effect on Serotonin producing neurons 2 wks: 83-95% reduction in serotonin axon density. 7 yrs: some recovery occurs, but significant loss of serotonin neurons has occurred.

  25. PMA • Effects similar to that of MDMA, but more toxic. • Is extremely potent and lethal. • Schedule 1 Drug in 1973 • Sold in tablet, capsule, or powder form. • Administered orally, inhaled, or injected. • >50 mg = LETHAL, causing cardiac arrhythmia, renal failure, vomiting, hyperthermia, convulsions, and death. • Street Names: Death, Mitsubishi Double-Stack.

  26. PMA Cont. • 1973: produced in Canada in clandestine labs. • 11 deaths attributed to its use in this year alone. • 2000: 7 deaths due to PMA use. • Victims believed they were taking ecstasy, so they accidentally overdosed.

  27. Serotonin-like Hallucinogens

  28. Also called Indoleamine Psychedelics • Act as agonist of Serotonin Receptors • specifically 5-HT2 Serotonin Receptors

  29. Examples:LSDPsilocybinPsilocinDMTBufotenineOloliuquiHarmine

  30. LSDLysergic Acid Diethylamide

  31. Street Names Acid, Battery Acid, Pane, Brown Bombers, Coffee, Crystal Tea, Dots, Golden Dragon, Haze, Looney Toons, Microdot, Lucy, Paper Acid, Pearly Gates, Pink Panther, Rainbow, Superman, White Lightening, Window Glass, Yin Yang, Zen, Yellow Sunshine, Sugar Cubes, & others.

  32. Derived from ergot alkaloids of the rye fungus. • Colorless, odorless, bitter taste. • Most potent mood & perception altering drug known to man. (can cause effects at 25 μg = in weight to a few grains of salt). • Can be synthesized in 1 week • Was used to treat alcoholism, paranoia, schizophrenia, and autism.

  33. History • 1938: Albert Hofmann synthesizes LSD-25 • 1943: Hofmann discovers hallucinogenic effects 1st hand when he accidentally ingests it. • Later he ingests 0.25 mg of it thinking it is a minimal dose, when in actuality it is 10 times the dose needed to produce an effect. “My visual field wavered and everything appeared deformed as in a faulty mirror. Space and time became more and more disorganized and I was overcome by fear that I was going out of my mind… It was particularly striking how acoustic perceptions, such as the noise of water gushing from a tap or the spoken word, were transformed into optical illusions.”

  34. History Cont. • 1950-1963: LSD used experimentally in mental facilities as treatment for mental disorders. • 1950’s: CIA & Army conduct secret experiments on human subjects using LSD. • 1953: Frank Olsen, a biochemist, kills himself after unknowingly consuming a drink containing LSD. • 1966: Timothy Leary, an former professor at Harvard, forms a religion called “League of Spiritual Discovery” in an attempt to use LSD and other hallucinogens legally.

  35. History Cont. • 1976: truth about the CIA & Army experiments are uncovered, revealing that nearly 585 soldiers and 900 civilians were given LSD without their knowledge for research purposes. • March 31, 2003: DEA busts the biggest LSD lab in history, seizing 41.3 kg or 91 lbs. of LSD.

  36. LSD in Popular Culture • Timothy Leary was a psychologist in the 1960’s advocating LSD use to enhance awareness. He began running experiments with subjects under the influence of LSD. Jerry Garcia was among them. • He also coined the phrase: “Tune in, Turn on, Drop out.” • After being removed from his position at Harvard, Leary founded two institutions for further LSD study.

  37. LSD in popular culture cont. • Lewis Carroll's Through the Looking Glass written about an LSD experience. • Popular musicians of the 1960’s greatly influenced by LSD. Ex- Beatles, Grateful Dead etc.

  38. Pharmacokinetics • Administered orally, smoked, snorted, or injected. • Doses 25-300 μg. (lethal dose = 14,000 μg) • Microdots: tablet form, Window panes: LSD in gelatin, Blotter acid: liquid added to paper, Sugar cubes: LSD in sugar cubes. • Absorbed within 1 hour. • Effects last 6-12 hours. • Diffuses across all barriers in body • Metabolized in liver and excreted in urine • No physical/physiological dependence • Few if any withdrawal symptoms • Tolerance and cross-tolerance to other hallucinogens does occur. (is lost within days after cessation of use).

  39. Pharmacodynamics • Binds to 5-HT2 serotonin receptors • Effects due to disruption of raphe nuclei (pons/medulla), which filters incoming sensory stimuli, creating surge of sensory information and overload of brain circuits. • Effects cerebral cortex (involved in mood, cognition, and perception) & locus ceruleus (receives sensory info) • LSD in high concentrations in iris of eye.

  40. Effects • Dilation of pupils, dizziness, dreamy detached feelings, changes in time perception, color/smells/sounds intensified, increase heart rate & blood pressure, sweating, dry mouth, hallucinations. • At High doses causes nausea, tremors, & confusion. • Moods typically depends on mood prior to use, causing those to become intensified. • However, moods can change quickly from euphoria to terror and panic.

  41. 2 Types of Emotional Responses to LSD: • Ecstatic-Transcendental Reactions: users become talkative, euphoric, ideas seem to have great importance. • Panic & Psychotic-like Reactions: users experience intense anxiety & fear, lose control of thoughts & emotions, become paniced. Known as aBad Trip • Can result in accidents or accidental suicides due to individual attempting to flee panic and terror they are experiencing.

  42. Long-Term Effects • Psychosis = dramatic mood swings • HPPD (Hallucinogen Persisting Perception Disorder) = also called Flashbacks. Former users experience spontaneous/repeated/continuous sensory distortions (seeing false motions or trails, etc.)

  43. DMT(Dimethyltryptamine) • Short-acting serotonin agonist (30 min) = Called “businessman’s lunch break drug” • Produces LSD-like effects • snorted or smoked • Can’t be taken orally, because acid in stomach destroys drug before absorption can occur. • Metabolized by MAO (monoamine oxidase) • Found in Leguminous trees & shrubs in West Indies and South America • Dose 60-150 mg

  44. Bufotenine • Found in toad skins • Metabolized by MAO

  45. Psilocybin/Psilocin(4-phosphoryl-DMT)/(4-hydroxy-DMT) • Found in psiloycbe mexicana mushroom • Peak effects within 2 hours, and last 6-10 hours. • Psilocybin broken down into psilocin (active psychedelic agent). • Eaten dried or fresh • Hallucinogenic effects at doses > 4 mg • Dried mushroom contains 0.2-0.4% psilocybin • Street Names: mushrooms, magic mushrooms, shrooms, Musk, Silly Putty, Simple Simon.

  46. Psilocybin/Psilocin History • 1955: identified by Gordon Wasson • 1958: extracted by Albert Hofmann • Ate 32 mushrooms to discover effect.

  47. Ololiuqui • Found in morning glory seeds • Used by tribes in Central & South America • 100+ seeds creates hallucinations, distorted visions, confusion. • Side Effects: nausea, vomiting, headache, & sleepiness.
