Hallucinogens and Dissociative Drugs Long-Term Effects of Hallucinogens See page 5. from the director: Research Report Series Hallucinogens and dissociative drugs— which have street names like acid, angel dust, and vitamin K—distort the way a user perceives time, motion, colors, sounds, and self.

According to the 2012 National Survey on Drug Use and Health, more than 180,000 Americans aged 12 and older reported current (past- month) use of LSD and 32,000 reported current use of PCP.1 New hallucinogenic/dissociative drugs have also emerged on the scene in recent years. Salvia, historically used by indigenous tribes of Southern Mexico during religious rituals, has replaced LSD and PCP as the most commonly used hallucinogenic drug. In fact, past-year use of salvia among the nation’s 12th-grade students is While regular use of hallucinogenic and dissociative drugs in general has more than 1.5 times that of LSD (3.4 remained relatively low in recent years, a recent study reported that the United percent versus 2.2 percent) and almost States ranks first among 36 nations in the proportion of high school students 5 times that of PCP (3.4 percent ever using LSD or other hallucinogens in their lifetime (6 percent versus 2 versus 0.7 percent).2 percent in Europe).3 Why Do People Take Hallucinogenic or Dissociative Drugs? Hallucinogenic and dissociative drugs have been used for a variety of reasons.4,5 Historically, hallucinogenic plants have been used for religious rituals to induce states of detachment from reality and precipitate “visions” thought to provide mystical insight or enable contact with a spirit world or “higher power.” More recently, people report using hallucinogenic drugs for more social or recreational purposes, including to have fun, help them deal with stress, or enable them to enter into what they perceive as a more enlightened sense of thinking or being. Hallucinogens have also been investigated as therapeutic agents to treat diseases associated with perceptual distortions, such as schizophrenia, obsessive- compulsive disorder, bipolar disorder, and dementia. NIDA Research Report Series 3 How Do Hallucinogens (LSD and Psilocybin) Affect the Brain and Body? How Do Hallucinogens Work? Classic hallucinogens are thought to produce their perception-altering effects by acting on neural circuits in the brain that use the neurotransmitter serotonin.6-9 Specifically, some of their most prominent effects occur in the prefrontal cortex—an area involved in mood, cognition, and perception—as well as other regions important in regulating arousal and physiological responses to stress and panic.

  • Monitoring Anesthetic Depth
    ANESTHETIC MONITORING Lyon Lee DVM PhD DACVA MONITORING ANESTHETIC DEPTH • The central nervous system is progressively depressed under general anesthesia. • Different stages of anesthesia will accompany different physiological reflexes and responses (see table below, Guedel’s signs and stages). Table 1. Guedel’s (1937) Signs and Stages of Anesthesia based on ‘Ether’ anesthesia in cats. Stages Description 1 Inducement, excitement, pupils constricted, voluntary struggling Obtunded reflexes, pupil diameters start to dilate, still excited, 2 involuntary struggling 3 Planes There are three planes- light, medium, and deep More decreased reflexes, pupils constricted, brisk palpebral reflex, Light corneal reflex, absence of swallowing reflex, lacrimation still present, no involuntary muscle movement. Ideal plane for most invasive procedures, pupils dilated, loss of pain, Medium loss of palpebral reflex, corneal reflexes present. Respiratory depression, severe muscle relaxation, bradycardia, no Deep (early overdose) reflexes (palpebral, corneal), pupils dilated Very deep anesthesia. Respiration ceases, cardiovascular function 4 depresses and death ensues immediately. • Due to arrival of newer inhalation anesthetics and concurrent use of injectable anesthetics and neuromuscular blockers the above classic signs do not fit well in most circumstances. • Modern concept has two stages simply dividing it into ‘awake’ and ‘unconscious’. • One should recognize and familiarize the reflexes with different physiologic signs to avoid any untoward side effects and complications • The system must be continuously monitored, and not neglected in favor of other signs of anesthesia. • Take all the information into account, not just one sign of anesthetic depth. • A major problem faced by all anesthetists is to avoid both ‘too light’ anesthesia with the risk of sudden violent movement and the dangerous ‘too deep’ anesthesia stage.

  • Hallucinogens
    Hallucinogens What Are Hallucinogens? Hallucinogens are a diverse group of drugs that alter a person’s awareness of their surroundings as well as their thoughts and feelings. They are commonly split into two categories: classic hallucinogens (such as LSD) and dissociative drugs (such as PCP). Both types of hallucinogens can cause hallucinations, or sensations and images that seem real though they are not. Additionally, dissociative drugs can cause users to feel out of control or disconnected from their body and environment. Some hallucinogens are extracted from plants or mushrooms, and others are synthetic (human-made). Historically, people have used hallucinogens for religious or healing rituals.

  • From Sacred Plants to Psychotherapy
    From Sacred Plants to Psychotherapy: The History and Re-Emergence of Psychedelics in Medicine By Dr. Ben Sessa ‘The rejection of any source of evidence is always treason to that ultimate rationalism which urges forward science and philosophy alike’ - Alfred North Whitehead Introduction: What exactly is it that fascinates people about the psychedelic drugs? And how can we best define them? 1. Most psychiatrists will define psychedelics as those drugs that cause an acute confusional state. They bring about profound alterations in consciousness and may induce perceptual distortions as part of an organic psychosis. 2. Another definition for these substances may come from the cross-cultural dimension. In this context psychedelic drugs may be recognised as ceremonial religious tools, used by some non-Western cultures in order to communicate with the spiritual world. 3. For many lay people the psychedelic drugs are little more than illegal and dangerous drugs of abuse – addictive compounds, not to be distinguished from cocaine and heroin, which are only understood to be destructive - the cause of an individual, if not society’s, destruction. 4. But two final definitions for psychedelic drugs – and those that I would like the reader to have considered by the end of this article – is that the class of drugs defined as psychedelic, can be: a) Useful and safe medical treatments. Tools that as adjuncts to psychotherapy can be used to alleviate the symptoms and course of many mental illnesses, and 1 b) Vital research tools with which to better our understanding of the brain and the nature of consciousness. Classifying psychedelic drugs: 1,2 The drugs that are often described as the ‘classical’ psychedelics include LSD-25 (Lysergic Diethylamide), Mescaline (3,4,5- trimethoxyphenylathylamine), Psilocybin (4-hydroxy-N,N-dimethyltryptamine) and DMT (dimethyltryptamine).

  • Acute Toxicity Associated with the Recreational Use of the Novel Dissociative Psychoactive Substance Methoxphenidine
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2014 Acute toxicity associated with the recreational use of the novel dissociative psychoactive substance methoxphenidine Hofer, K E ; Degrandi, C ; Müller, D M ; Zürrer-Härdi, U ; Wahl, S ; Rauber-Lüthy, C ; Ceschi, A Abstract: INTRODUCTION: Methoxphenidine is a novel dissociative designer drug of the diarylethy- lamine class which shares structural features with phencyclidine (PCP), and is not at present subject to restrictive regulations. There is very limited information about the acute toxicity profile of methoxpheni- dine and the only sources are anonymous internet sites and a 1989 patent of the Searle Company. We report a case of analytically confirmed oral methoxphenidine toxicity. CASE DETAILS: A 53-year-old man was found on the street in a somnolent and confusional state. Observed signs and symptoms such as tachycardia (112 bpm), hypertension (220/125 mmHg), echolalia, confusion, agitation, opisthotonus, nys- tagmus and amnesia were consistent with phencyclidine-induced adverse effects. Temperature (99.1°F (37.3°C)) and peripheral oxygen saturation while breathing room air (99%) were normal. Laboratory analysis revealed an increase of creatine kinase (max 865 U/L), alanine aminotransferase (72 U/L) and gamma-glutamyl transpeptidase (123 U/L). Methoxphenidine was identified by a liquid chromatogra- phy tandem mass spectrometry toxicological screening method using turbulent flow online extraction in plasma and urine samples collected on admission. The clinical course was favourable and signs and symptoms resolved with symptomatic treatment. CONCLUSION: Based on this case report and users’ web reports, and compatible with the chemical structure, methoxphenidine produces effects similar to those of the arylcyclohexylamines, as PCP.

  • MDMA Get 24/7 Help Now!
    MDMA Illicit substances can be categorized into one of three major drug types: depressants, stimulants, and hallucinogens. Depressants consist of substances that slow or “depress” the body’s normal functions. In contrast, stimulants do the opposite: they jump-start the central nervous system, increasing the user’s heart rate, blood pressure, respiration and body temperature. Hallucinogens are unlike either of the other illicit drug groups; as the name suggests, these are drugs that cause hallucinations, whether visual or auditory. Sometimes, illicit drugs can fall into two of these three categories. Methylenedioxy-methamphetamine, more commonly called MDMA, is one such example. It falls into two categories: stimulant and hallucinogen. MDMA drug addiction is one type of addiction treatment available through the Wellness Retreat Recovery program. Get 24/7 help now! All calls are free and confidential! 888-821-0238 MDMA About MDMA Like any other stimulant, MDMA increases the user’s energy, blood pressure, heart rate, and respiration. Still, MDMA stands apart from other stimulant drugs because it triggers a number of effects that are more common among hallucinogens. In fact, MDMA is most well-known for being the active ingredient in Ecstasy, a “club drug” that distorts the user’s senses and evokes uninhibited feelings of sensuality. Other effects include: increased sensory reception (i.e. fabric seems softer, drinks taste stronger, etc.) increased sensitivity to light emotional exacerbation sexual arousal Overall, MDMA has been known to intensity users’ emotional and physical experiences. However, this does not make MDMA a “safe” drug as many users might argue. The Effects of MDMA on the Brain Just like with any other illicit substance, continued use of MDMA can lead to addiction.

  • Pharmacology – Inhalant Anesthetics
    Pharmacology- Inhalant Anesthetics Lyon Lee DVM PhD DACVA Introduction • Maintenance of general anesthesia is primarily carried out using inhalation anesthetics, although intravenous anesthetics may be used for short procedures. • Inhalation anesthetics provide quicker changes of anesthetic depth than injectable anesthetics, and reversal of central nervous depression is more readily achieved, explaining for its popularity in prolonged anesthesia (less risk of overdosing, less accumulation and quicker recovery) (see table 1) Table 1. Comparison of inhalant and injectable anesthetics Inhalant Technique Injectable Technique Expensive Equipment Cheap (needles, syringes) Patent Airway and high O2 Not necessarily Better control of anesthetic depth Once given, suffer the consequences Ease of elimination (ventilation) Only through metabolism & Excretion Pollution No • Commonly administered inhalant anesthetics include volatile liquids such as isoflurane, halothane, sevoflurane and desflurane, and inorganic gas, nitrous oxide (N2O). Except N2O, these volatile anesthetics are chemically ‘halogenated hydrocarbons’ and all are closely related. • Physical characteristics of volatile anesthetics govern their clinical effects and practicality associated with their use.
