LSD

Lysergic acid diethylamide, commonly known as LSD (from German Lysergsäure-diethylamid), and known colloquially as acid, is a potent psychedelic drug. Effects typically include intensified thoughts, emotions, and sensory perception. At sufficiently high dosages LSD manifests primarily mental, visual, and auditory hallucinations. Dilated pupils, increased blood pressure, and increased body temperature are typical. Effects typically begin within half an hour and can last for up to 20 hours (although on average the trip lasts 8-12 hours). LSD is also capable of causing mystical experiences and ego dissolution. It is used mainly as a recreational drug or for spiritual reasons. LSD is both the prototypical psychedelic and one of the "classical" psychedelics, being the psychedelic with the greatest scientific and cultural significance. LSD is synthesized as a solid compound, typically in the form of a powder or a crystalline material. This solid LSD is then dissolved in a liquid solvent, such as ethanol or distilled water, to create a solution. The liquid serves as a carrier for the LSD, allowing for accurate dosage and administration onto small pieces of blotter paper called tabs. LSD is typically either swallowed or held under the tongue. LSD is pharmacologically considered to be non-addictive with low potential for abuse. Adverse psychological reactions are possible, such as anxiety, paranoia, and delusions. LSD is active in small amounts relative to other psychoactive compounds with doses measured in micrograms. It is possible for LSD to induce either intermittent or chronic visual hallucinations, in spite of no further use. Common effects include visual snow and palinopsia. In cases where this causes distress or impairment it is diagnosed as hallucinogen persisting perception disorder (HPPD). While overdose from LSD is unknown, LSD can cause injury and death as a result of accidents stemming from psychological impairment.
