A long history of using hallucinogenic plants exists among humans for ceremonial and religious purposes. It is difficult to define psychoactive drugs that are so diverse in chemical structures. Hallucinogens are a group of drugs that alter an individual’s awareness of Classic hallucinogens Common classic hallucinogens include: 49 ● D-lysergic acid diethylamide (LSD) is one of the most potent mind-altering chemicals. It is a clear or white odorless substance found in a fungus that grows on rye or grains. ● Psilocybin originates from mushrooms in tropical and subtropical regions of South America, Mexico, and United States ● Peyote (mescaline) is a small spineless cactus with mescaline as its main ingredient. ● DMT (N,N-dimethyltryptamine) is a powerful chemical found in plants in the Amazon. Ayahuasca is a tea from these plants, called hoasca, aya, and yage. ● 251-NBOMe is a synthetic hallucinogen similar to both LSD and MDMA, but much more potent. Classic hallucinogens temporarily disrupt communication through the brain and spinal cord. Additionally, some interfere with serotonin, which
surroundings, emotions, and thoughts. Despite their name, hallucinogens do not consistently cause hallucinations. 48 These are divided into two categories including classic hallucinogens and dissociative drugs. regulates mood, sensory perception, sleep, hunger, body temperature, sexual behavior, and intestinal muscle control. These hallucinogens cause individuals to see images, hear sounds, and feel sensations that seem real, which generally begin within 20-90 minutes and can last from 15 minutes to 12 hours. These are commonly referred to as a trip by the individual. The short-term effects can range from tachycardia and nausea to seeing intense colors and changes sense of time. Other short-term effects of hallucinogens include increased blood pressure, tachypnea, and hyperthermia, loss of appetite, dry mouth, spiritual experiences, relaxation, uncoordinated movements, excessive sweating, panic, paranoia and psychosis, and bizarre behaviors. Long-term effects include persistent psychosis and hallucinogen persistent perception disorder, which are evident in individuals with mental illness.
DISSOCIATIVE HALLUCINOGENS
Common dissociative drugs include: ● PCP (phencyclidine), also known as “angel dust,” which was developed as a general anesthesia but is no longer used because of serious side effects. Now it is found in a variety of forms. Users snort PCP powder, swallow tablets and capsules, or smoke the drug by applying it (in powder form) to a leafy substance such as marijuana. In addition, users increasingly are dipping marijuana or tobacco cigarettes in liquid PCP and smoking them. ● Ketamine is a dissociative anesthetic for animals and humans and is a noncompetitive N-methyl-d- aspartate receptor antagonist. It is commonly used medically as an analgesic and sedative but is also being explored for its therapeutic effects that offer a potential alternative treatment for depression, suicidal ideation, substance use disorders, and
PTSD. 50 This has also been used as a date rape drug. ● Dextromethorphan (DXM) is an over-the-counter cold and cough medicine. ● Salvia is a plant common to southern Mexico and Central and South America. This drug is ingested by chewing fresh leaves and drinking the extracted juice. Dissociative hallucinogens interfere with glutamate, which regulates pain perception, environmental response, emotion, learning and memory. Dissociative drugs can cause numbness, disorientation, loss of coordination, hallucinations, and increases in blood pressure, heart rate and body temperature; long term effects may include speech problems, memory loss, weight loss, anxiety and depression, or suicidal thoughts.
