Drugs of Abuse: Psychedelic Agents By: Kimber Bailey Topics of Discussion Hallucinogens Psychedelic Drugs Classes LSD Psilocybin mushrooms Uses for Psychedelic Drugs Defined Types Previous practices Past beliefs Psychedelic Psychotherapy Psycholytic Therapy Psychedelic Therapy Current Research and Therapy Hallucinogens These are mind altering elements that induce experiences that are qualitatively different from those experienced in ordinary consciousness. Almost all hallucinogens contain nitrogen and are therefore classified as alkaloids. Many hallucinogens have chemical structures similar to those of human neurotransmitters, such as serotonin, and temporarily modify the actions of neurotransmitters and receptor sites. Hallucinogens Serotonin Neurotransmitter: Norepinephrine http://en.wikipedia.org/wiki/Norepinephrine http://en.wikipedia.org/wiki/Serotonin Hallucinogen: Mescaline http://en.wikipedia.org/wiki/Mescaline Hallucinogens Irony of Hallucinogenic Drugs These drugs do not actually cause hallucinations. Hallucinogens simply modify a person’s regular perception. The person is usually quite aware of the illusions and nature of the perceptions that he or she is experiencing. Hallucinogens Common Misinterpretation It is believed that the effects of hallucinogens mimic psychological conditions. For example, many people believe the use of hallucinogens will lead to the following: Psychosis Schizophrenia Thought disorder Hallucinogens However, these types of drugs can actually result in psychological trauma if consumed without a person’s knowledge. Date rape drugs are a common case that cause extreme vomiting and loss of memory. Hallucinogens There are three types of hallucinogens: 1. Psychedelics psychoactive drugs whose primary action is to alter the thought processes of the brain 2. Dissociatives reduce or block signals to the conscious mind from other parts of the brain, typically the physical senses 3. Deliriants also called anticholinergics a special class of dissociatives which are antagonists for the acetylcholine receptors These three drug classes can all cause subjective changes in one’s perception of thought, emotion, and consciousness. Psychedelic Drugs Many psychedelic drugs are thought to disable filters which keep signals that are unrelated to everyday functions from reaching the conscious mind. This filtering has been described as mind expanding, or consciousness expanding. The drug “expands” the realm of experience available to conscious awareness. These filtered signals are presumed to originate in several other functions of the brain, including the senses, emotions, memories, and the subconscious mind. Psychedelic Drugs The most remarkable characteristic of psychedelic drugs is the variation in their effects. The level and type of effect that is achieved is dependent among: Dosage Set/Type Setting Many psychedelics are extremely nontoxic. It is difficult to overdose on these compounds alone. Combinations with other drugs make overdosing more likely. Psychedelic Drugs There are three common classes: Serotonergic Psychedelics These Empathogens and Entactogens These are serotonin 5-HT2A receptor agonists. are serotonin releasers. Cannabinoids These are CB-1 cannabinoid receptor agonists. Serotonergic Psychedelics This class includes the major hallucinogens Tryptamine-based compounds Phenethylamine-based compounds LSD and psilocybin Mescaline and 2C-B At lower doses, these include sensory distortions such as the warping of surfaces, shape suggestibility, and color variations. Higher doses often cause intense and fundamental distortions of sensory perception such as synesthesia or the experience of additional spatial or temporal dimensions. Empathogens and Entactogens These are phenethylamines. Examples include MDMA (or ecstasy), MDA, and similar drugs. The effects are characterized by feelings of openness, euphoria, empathy, love, and heightened self-awareness. However, visual hallucinations is not experienced by the user. Cannabinoids The cannabinoids are Tetrahydrocannabinol (THC) and related compounds. These compounds are capable of activating the body’s endogenous cannabanoid system. The effects associated with these drugs are General change in consciousness, mild euphoria, feelings of general well-being. Relaxation or stress reduction. Increased appreciation of humor, music and other art, joviality, metacognition and introspections. Enhanced recollection of episodic memory, increased sensuality, loss of inhibition, creative or philosophical thinking. Disruption of linear memory, paranoia, agitation, and anxiety. Two Examples of Psychedelic Drugs LSD http://www.usdoj.gov/dea/photos/lsd/lsd_blotter_full_sheet.jpg “acid” Psilocybin Mushrooms http://www.jeshannon.com/images/shrooms.jpg “shrooms” LSD Lyrsergic acid diethylamide, LSD, LSD-25, or acid is a semisynthetic psychedelic drug. LSD binds to most serotonin receptor subtypes except for serotonin 5-HT3 and serotonin 5-HT4. Recreational doses can affect 5-HT1A, 5-HT2A, 5HT2C, 5-HT5A, 5-HT5B, and 5-HT6 receptors. The hallucinogenic effects are attributed to its strong partial agonist effects at 5-HT2A receptors. Specific 5-HT2A agonist drugs are hallucinogenic, so large 5-HT2A specific antagonists block the hallucinogenic activity of LSD. LSD http://en.wikipedia.org/wiki/LSD LSD LSD is, by mass, one of the most potent drugs yet discovered. Dosages are measured in micrograms. Doses of almost all other drugs, both recreational and medical, are measured in milligrams. While a typical single dose of LSD may be between 100 and 500 micrograms, threshold effects can be felt with as little as 20 micrograms. Dosages by frequent users can be as high as 1,200 micrograms, although such a high dosage may precipitate unpleasant physical and psychological reactions. LSD Estimates for the lethal dosage (LD50) of LSD range from 200 μg/kg to more than 1 mg/kg of human body mass. LSD is not considered to be addictive. There are no known human cases of such an overdose. Users do not exhibit the commonly accepted definitions of addiction and physical dependence. Rapid tolerance build-up prevents regular use. This tolerance diminishes after a few days’ abstention from use. LSD LSD’s psychological effects vary greatly from person to person, depending on factors such as previous experiences, state of mind and environment, as well as dose strength. LSD causes expansion and altered experience of senses, emotions, memories, time, and awareness for 6 to 14 hours, depending on dosage and tolerance. There is a reported 30% possibility of “flashbacks”. A psychological phenomenon in which an individual experiences an episode of some of LSD’s subjective effects long after the drug has worn off—sometimes weeks, months, or even years afterward. Flashbacks can incorporate both positive and negative aspects of LSD trips. Psilocybin Mushrooms Psilocybin is a psychedelic alkaloid of the tryptamine family and is found in psilocybin mushrooms. It is present in hundreds of species of fungi, including those of the genus Psilocybe and Panaeolus. The intensity and duration of recreational and entheogenic use of psilocybin mushrooms vary depending on species of mushrooms, dosage, individual physiology, and set and setting. Psilocybin Mushrooms http://en.wikipedia.org/wiki/Psilocybin Psilocybin Mushrooms Psilocybin is a prodrug that is converted, mostly in the liver, into the pharmacologically active compound psilocin in the body by dephosphorylation. It is broken down by monoamine oxidase. http://www.hallucinogen.dk/rusmidler/psykedelika/svampe/images/biokemi/dephosphorylase.gif This chemical reaction takes place under strongly acidic conditions or enzymatically by phosphatases in the body. Psilocybin Mushrooms Many types of psilocybin mushrooms bruise blue when handled or damaged. Psilocybin is rapidly dephosphorylated in the body to psilocin which then acts as a partial agonist at the 5-HT2A serotonin receptor in the brain where it mimics the effects of serotonin. This is due to the oxidation of active compounds, however, bruising is not a definitive method of determining a mushroom’s potency. Psilocybin is an 5-HT1A and 5-HT2A/2C agonist. The toxicity of psilocybin is relatively low – approximately 12.5 mg/kg The psilocybin content of psychoactive mushrooms is quite variable and depends on species growth conditions, drying conditions, and mushroom size. Psilocybin Mushrooms Effects last from 2-6 hours depending on dose, species, individual brain chemistry, and individual metabolism. Difficult trips may occur when psychedelic compounds are taken in a non-supportive of inadequate environment, by an inexperienced person, or in an unexpectedly high doses. At low doses, hallucinatory effects occur. The effects are often pleasant, even ecstatic. They including a deep sense of connection to others, confusion, hilarity, and a general feeling of connection to nature and the universe. Walls seem to breathe, a vivid enhancement of colors occurs, and organic shapes become animated. At higher doses, experiences tend to be less social and more entheogenic. It often catalyzing intense spiritual experiences. Uses for Psychedelic Drugs Early military research focused on their use as incapacitating agents. They were hypothesized to induce a subject to talk during an interrogation. The drugs use was very inconsistent. The individuals did not consistently speak accurately and coherently. The types of hallucinogens have been used within medicinal and religious traditions around the world. They have been used in shamanic forms of ritual healing and divination, in initiation rites, and in the religious rituals of syncretistic movements. Uses for Psychedelic Drugs The rise of the Abrahamic religions (Judaism, Christianity, and Islam) caused a decline of entheogenic use. The authority of scripture and the priesthood gradually reduced the role granted to direct spiritual experience, especially by the laity. Interest in the drugs tended to focus on either the potential for psychotherapeutic applications of the drugs. Also, hallucinogens were used to produce a “controlled psychosis”. Ethenogenic is the term used to describe the effects of the drugs during ceromonial or spiritual use. This use was in order to understand psychotic disorders such as schizophrenia. Hallucinogens were also researched in several countries for their potential as agents of chemical warfare. Psychedelic Psychotherapy Psychedelic psychotherapy refers to psychotherapeutic practices involving the use of psychedelic drugs. The use of the term psychedelic emphasizes the ability of psychedelic drugs to facilitate exploration of the psyche, which is fundamental to most methods of psychedelic psychotherapy. Many studies found that the use of psychedelic drug greatly facilitated psychotherapeutic processes and proved particularly useful for patients with problems that were otherwise difficult to treat. Alcoholics, drug addicts, sociopaths, and psychopaths Hallucinogen Persisting Perception Disorder (HPPD) is a diagnosed condition where some effects of hallucinogenic drugs persist after a long time. Medical technology has yet to determine what causes this condition. Psychedelic Psychotherapy Some hypothesize that drugs such as LSD may be useful in psychotherapy, especially when the patient is unable to “unblock” repressed subconscious material through other psychotherapeutic methods. Experiments concerning the use of psilocybin in the treatment of personality disorders and other uses in psychological counseling have also been conducted. Psychedelic Psychotherapy Multidisciplinary Association for Psychedelic Studies (MAPS) began in 2001 to study the effects of psilocybin on patients with obsessive-compulsive disorder. http://www.maps.org/pioneers/images/hofmann_large.jpg http://www.maps.org/pioneers/images/huxley_large.jpg Psychedelic Psychotherapy Psycholytic Therapy: Primarily studied in Europe, psycholytic therapy involves the use of low to medium doses of psychedelic drugs, repeatedly at intervals of 1-2 weeks. The therapist is present during the peak of the experience and at other times as required. He or she assists the patient in processing material that arises and is present to offer support when necessary. Psychedelic Therapy Primarily researched in North America, psychedelic therapy involves the use of very high doses of psychedelic drugs, with the aim of promoting a transcendental, ecstatic, religious, or mystical peak experience. Psychedelic Psychotherapy Current Research and Therapy: Current research therapy includes using psilocybin with terminally ill patients in the intention of helping them to accept their condition. The stress and anxiety experienced by many terminally ill patients causes them much suffering in the last months of their lives Some patients claimed that the use of psilocybin helped them tremendously in terms of acceptance. Other therapies include the use of MDMA, more commonly known as Ecstasy, to treat Post-Traumatic Stress Disorder (PTSD).
