1 1 Hallucinogens (Psychedelics)

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

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

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

5 5 Nature of hallucinogens PsychedelicPsychotogenicPsychotomimetic

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

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

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

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

10 10 Traditional Hallucinogens Physiological effects 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 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 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 Effects of this hallucinogen can last 2-12 hours Tolerance to the effects of LSD develops very quickly Tolerance to the effects of LSD develops very quickly

12 12 Other LSD types agents Mescaline (Peyote) 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 13 Other LSD types agents Psilocybin - its principal source is the Psilocybe mexicana mushroom 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 14 Other LSD types agents Dimethyltryptamine (DMT) 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 15 Other Hallucinogenic (LSD type) Nutmeg Nutmeg – Myristica oil responsible for physical effects – High doses can be quite intoxicating – Can also cause unpleasant trips

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

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

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

20 20 Other hallucinogens Phencyclidine (PCP) 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 21 Other hallucinogens Phencyclidine (PCP) physiological effects Phencyclidine (PCP) physiological effects – Hallucinogenic effects, stimulation, depression, anesthesia, analgesia – Large doses can cause coma, convulsions, and death PCP psychological effects PCP psychological effects – Feelings of strength, power, invulnerability; perceptual distortions, paranoia, violence, psychoses,

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

56 56 Botanical intoxicants…future mayhem? None of these plants are addictive, other than cultivation of the opium poppy in the U.S., which is not common. Illicit cultivation of Cannabis spp., of course, continues. None of these plants are addictive, other than cultivation of the opium poppy in the U.S., which is not common. Illicit cultivation of Cannabis spp., of course, continues. Eradication of the illicit drug market of hallucinogens may drive the “resourceful” to these botanicals more than today. Eradication of the illicit drug market of hallucinogens may drive the “resourceful” to these botanicals more than today. It is not feasible to eradicate these botanicals from U.S. territory It is not feasible to eradicate these botanicals from U.S. territory The Internet will drive an ever wider dissemination of information on these botanicals to those seeking this information The Internet will drive an ever wider dissemination of information on these botanicals to those seeking this information
