The Effects of Lsd Essay Example for Free
The Effects of Lsd Essaylysergic acid diethylamide was first synthesized on November 16, 1938 by Swiss chemist Albert Hofmann at the Sandoz Laboratories in Basel, Switzerland as sidetrack of a large research program searching for medically useful ergot alkaloid derivatives. LSDs psychedelic properties were discovered 5 years later when Hofmann himself accidentally ingested an dark quantity of the chemical. The first intentional ingestion of LSD occurred on April 19, 1943, when Hofmann ingested 250 mg of LSD. He said this would be a threshold dose based on the dosages of other ergot alkaloids. Hofmann found the personal effect to be much stronger than he anticipated. Sandoz Laboratories introduced LSD as a psychiatric drug in 1947. Beginning in the 1950s the US of import Intelligence Agency began a research program code named Project MKULTRA. Experiments included administering LSD to CIA employees, military personnel, doctors, other administration agents, prostitutes, mental ly ill patients, and members of the general public in order to study their reactions, usually without the subjects knowledge. The project was revealed in the US congressional Rockefeller Commission cut through in 1975.In 1963 the Sandoz patents expired on LSD. Also in 1963, the US Food and Drug Administration classified LSD as an Investigational New Drug, which meant new restrictions on medical and scientific use. Several figures, including Aldous Huxley, Timothy Leary, and Al Hubbard, began to advocate the consumption of LSD. LSD became central to the counterculture of the 1960s. On October 24, 1968, possession of LSD was made illegal in the United States. The last FDA approved study of LSD in patients ended in 1980, while a study in healthy volunteers was made in the late 1980s.Legally approved and regulated psychiatric use of LSD continued in Switzerland until 1993. Today, medical research is resuming around the world. Lysergic acid diethylamide, abbreviated LSD or LSD-25, bes ides known as lysergide (INN) and colloquially as acid, is a semisynthetic psychedelic drug of the ergoline family, well known for its psychological effects which thunder mug include altered thinking processes, closed and open eye visuals, synesthesia, an altered sense of time and spiritual experiences, as well as for its key region in 1960s counterculture.It is used mainly as an entheogen, recreational drug, and as an agent in psychedelic therapy. LSD is non-addictive, is not known to cause superstar damage, and has extremely low toxicity relative to dose. However, adverse psychiatric reactions such as anxiety, paranoia, and delusions argon possible. LSD was first synthesized by Albert Hofmann in 1938 from ergotamine, a chemical derived by Arthur Stoll from ergot, a grain fungus that typically grows on rye. The short form LSD comes from its early code name LSD-25, which is an abbreviation for the German Lysergsaure-diethylamid followed by a sequential number.LSD is sensitive to oxygen, ultraviolet light, and chlorine, especially in solution, though its potency may last for years if it is stored away from light and moisture at low temperature. In pure form it is a colorless, odorless, tasteless solid. LSD is typically delivered orally, usually on a substrate such as receptive blotter paper, a sugar cube, or gelatin. In its liquid form, it crowd out excessively be administered by intramuscular or intravenous injection. LSD is precise potent, with 2030 g (micrograms) being the threshold dose.New experiments with LSD have started in 2009 for the first time in 40 years. Introduced by Sandoz Laboratories, with trade-name Delysid, as a drug with various psychiatric uses in 1947, LSD quickly became a therapeutic agent that appeared to show great promise. In the 1950s, officials at the U. S. Central Intelligence Agency (CIA) thought the drug might be applicable to mind control and chemical warfare the agencys MKULTRA research program propagated the drug among untried servicemen and students.The subsequent recreational use of the drug by youth culture in the Western world during the 1960s led to a political firestorm that resulted in its prohibition. Currently, a number of organizationsincluding the Beckley Foundation, MAPS, Heffter Research Institute and the Albert Hofmann Foundationexist to fund, encourage and coordinate research into the medicinal and spiritual uses of LSD and related psychedelics. LSD can cause pupil dilation, reduced or increased appetite, and wakefulness.Other physical reactions to LSD are highly variable and nonspecific, some of which may be secondary coil to the psychological effects of LSD. Among the give outed symptoms are numbness, weakness, nausea, hypothermia or hyperthermia, elevated blood sugar, goose bumps, heart rate increase, jaw clenching, perspiration, saliva production, mucus production, sleeplessness, hyperreflexia, and tremors. Some users, including Albert Hofmann, report a strong metallic taste for the duration of the effects.LSD is not considered addictive by the medical community. Rapid tolerance build-up prevents regular use,citation needed and cross-tolerance has been demonstrated amongst LSD, mescaline and psilocybin. This tolerance diminishes after a few days after cessation of use and is probably caused by down regulation of 5-HT2A receptors in the brain. LSDs psychological effects (colloquially called a trip) vary greatly from person to person, depending on factors such as previous experiences, state of mind and environs, as well as dose strength.They as well vary from one trip to another, and even as time pass during a single trip. An LSD trip can have long-term psych turned on(p) effects some users cite the LSD experience as causing significant changes in their temper and life perspective citation needed. Widely different effects emerge based on what Timothy Leary called set and setting the set being the general mindset of the user, and the setting being the physical and social environment in which the drugs effects are experienced.Some psychological effects may include an experience of radiant colors, objects and surfaces appearing to ripple or breathe, colored patterns bottom of the inning the closed eyelids (eidetic imagery), an altered sense of time (time seems to be stretching, repeating itself, changing speed or stopping), crawling geometric patterns overlaying walls and other objects, morphing objects, a sense that ones thoughts are spiraling into themselves, loss of a sense of identity or the ego (known as ego death), and other powerful psycho-physical reactions. Many users experience dissolution surrounded by themselves and the outside world.This unitive quality may play a role in the spiritual and religious aspects of LSD. The drug sometimes leads to disintegration or restructuring of the users historical personality and creates a mental state that some users report allows them to have more choice regarding the nature of th eir own personality. If the user is in a hostile or otherwise unsettling environment, or is not mentally prepared for the powerful distortions in perception and thought that the drug causes, effects are more likely to be unpleasant than if he or she is in a comfortable environment and has a relaxed, balanced and open mindset.LSD causes an altered sensory experience of senses, emotions, memories, time, and sense for 6 to 14 hours, depending on dosage and tolerance. Generally beginning within thirty to ninety minutes after ingestion, the user may experience anything from clear-sighted changes in perception to overwhelming cognitive shifts. Changes in auditory and visual perception are typical. Visual effects include the illusion of movement of atmospherics surfaces (walls breathing), after mage-like trails of moving objects (tracers), the appearance of moving colored geometric patterns (especially with closed eyes), an intensification of colors and brightness (sparkling), new textu res on objects, blurred vision, and shape suggestibility. Users commonly report that the inanimate world appears to animate in an unexplainable way for instance, objects that are static in three dimensions can seem to be moving relative to one or more additional spatial dimensions. Many of the basic visual effects resemble the phosphine seen after applying pressure to the eye and have also been studied under the name form constants.The auditory effects of LSD may include echo-like distortions of sounds, changes in ability to discern concurrent auditory stimuli, and a general intensification of the experience of music. Higher doses often cause intense and fundamental distortions of sensory perception such as synesthesia, the experience of additional spatial or temporal dimensions, and temporary dissociation. The potential uses of LSD end of life anxiety, alcoholism, pain, cluster headaches, spiritual, and creativity. These are the potential adverse effects adverse drug interactions, mental disorders, and suggestibility and also psychosis.
