Overview of the Category Hallucinogens are drugs that affect a person’s perceptions, sensations, thinking, self- awareness and emotions. The word “Hallucinogen” means something that causes hallucinations. Definition from The Random House College Dictionary (Revised Edition, 1980) A hallucination is a sensory experience of something that does not exist outside the mind. Seeing, hearing, smelling, tasting or feeling something that isn’t really there. Having distorted sensory perceptions, so that things look, sound, smell, etc. differently than they really are. Hallucinogenic drugs usually produce what are called pseudo-hallucinations: i.e. the user typically is aware that what he or she is seeing, hearing, smelling, etc. isn’t real, but is a product of the drug. But emphasize that the fact that the user knows the hallucinations aren’t real doesn’t make those hallucinations any less dangerous if they occur while driving.

In its simplest terms, it is a transposition of senses. Synesthesia can occur naturally in a small percentage of the population, and can differ from drug induced synesthesia. Examples: The user may “see a flash of color, or some other sight, when the telephone rings.” • Sounds for example, may be transposed into sights. • Sights may be transposed into odors. • The user may “smell” a particular fragrance when he or she looks at something painted yellow. • The illusions and distorted perceptions produced by hallucinogenic drugs may be very alarming, even terrifying. • They may produce panic and uncontrolled excitement. Point out that the expression “bad trip” refers principally to these panic filled reactions to Hallucinogens. The user may be unable to cope with the terror, and may attempt to flee wildly. A user who is emotionally or mentally unstable may become psychotic in response to this frightening experience.

In simple terms, a flashback is a vivid recollection of a portion of a hallucinogenic experience. A flashback does not occur because of a residual quantity of drug in the user’s body. Instead, a flashback essentially is a very intense daydream. But point out that subsequent use of the drug may precipitate a flashback, by causing the user to re-experience the frightening illusions of the previous “bad trip.” Revised: Drug Recognition Expert Course Session 14 10/2015 Hallucinogens Page 4 of 24 Session 14 - Hallucinogens Session 14 - Hallucinogens 3 Types of Flashbacks Sensory Perceptions Emotional • Most dangerous - feelings of panic, fear, etc., Delusion sensation of “bad trip” • A false belief Somatic • Altered body sensations, tremors, weakness, dizziness, crawly, tingly feeling on the skin Illusion Perceptual • Distortions of vision, hearing, smell, taste and • A false perception touch (associated with original “trip” least harmful, unless driving a motor vehicle) Drug Recognition Expert Course 14-7 Drug Recognition Expert Course 14-8 Types of Flashbacks There are three types of flashback: • Emotional: most dangerous - feelings of panic, fear, etc; the sensations of a “bad trip.” • Somatic: Altered body sensations, tremors, weakness, dizziness, crawly, tingly feelings on the skin. • Perceptual: Distortions of vision, hearing, smell, taste and touch (associated with original “trip” least harmful, unless driving a motor vehicle) Delusion and Illusion Remember that hallucinogens produce delusions, illusions, or both. • A delusion is a false belief. Example of a delusion: “I am an Elephant.” • An illusion is a false perception, i.e. a misrepresentation of what the senses are receiving. Example of an illusion: “I see an Elephant.” Revised: Drug Recognition Expert Course Session 14 10/2015 Hallucinogens Page 5 of 24 Session 14 - Hallucinogens Psychotomimetic “Psychotomimetic” means “something that mimics psychosis.” A psychosis is a major mental disorder. It implies a loss of touch with reality. Drug Recognition Expert Course 14-9 Because they often make the user appear to be psychotic, Hallucinogens are sometimes called psychotomimetic drugs. “Psychotomimetic” means “something that mimics psychosis.” A psychosis is a major mental disorder. It implies a loss of touch with reality. Point out some Hallucinogens may create a psychotomimetic response in the user, meaning that they literally appear to have psychosis. Some Hallucinogens come from natural sources, while others are synthetically manufactured. For your information: Other naturally occurring Hallucinogens include nutmeg, jimson weed, morning glory seeds, salvia divinorum, and bufotenine, a substance found in the glands of certain toads. Some regional or local Hallucinogens may be discussed in more detail. Peyote, Psilocybin and Salvia Divinorum are examples of naturally occurring Hallucinogens. Revised: Drug Recognition Expert Course Session 14 10/2015 Hallucinogens Page 6 of 24 LSD, TMA, DMT, MDMA, MDA, and 2CB are examples of synthetically manufactured Hallucinogens. For your information: Drugs such as MDA, MDMA, STP, and TMA all contain amphetamine based compounds. They are for this reason sometimes called “psychedelic amphetamines.” In essence, they are high powered CNS Stimulants that cause hallucinations. • LSD: Lysergic Acid Diethylamide. • 25I-NBOMe: 2-(4-iodo-2,5-dimethoxyphenyl)-N-(2-methoxybenzyl)ethanamine. This synthetic drug and analogs exhibit effects similar to LSD. Referred to as “N-Bomb” or “Smiles”. As of late 2013, 25I-NBOMe and analogs have been banned by DEA for a minimum of two years. • TMA: Trimethoxyamphetamine • DMT: Dimethyltryptamine • MDMA is an abbreviation for 3,4-Methylenedioxymethamphetamine and is commonly referred to as “Ecstasy.” It is a hallucinogen that also acts as a stimulant. It produces an energizing effect, as well as distortions in time and perception and enhances enjoyment from tactile experiences. • MDA is an abbreviation for 3,4-Methylenedioxyamphetamine. It is normally produced as a clear liquid, or as a white powder in capsule or tablet form. • 2CB (4-Bromo-2, 5-Dimethoxyphenethylamine) is a white powder usually found in pressed tablets or gel caps. It is considered a synthetic psychedelic
