Lysergic+acid+diethylamide+(LSD)

Lysergic acid diethylamide, abbreviated LSD or LSD-25, also known as lysergide and colloquially as 'acid', is a semisynthetic psychedelic drug of the ergoline family, well known for its psychological effects which can include altered thinking processes, closed and open eye visuals, synaesthesia, an altered sense of time and spiritual experiences, as well as for its key role 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 brain damage, and has extremely low toxicity relative to dose, although in rare cases adverse psychiatric reactions such as anxiety or delusions are possible.

LSD is manufactured from lysergic acid which occurs naturally in the ergot fungus that grows on wheat and rye. It is available in liquid, powder, tablet (microdots), and capsule form. The liquid is often applied to blotter paper squares (frequently with colorful designs), stickers, sugar cubes, candy, or soda crackers. LSD is also available in dropper bottles or in the form of gelatin sheets/shapes (window panes).



LSD's psychological effects (colloquially called a "trip") vary greatly from person to person, depending on factors such as previous experiences, state of mind and environment, as well as dose strength. They also vary from one trip to another, and even as time passes during a single trip. An LSD trip can have long-term psychoemotional effects; some users cite the LSD experience as causing significant changes in their personality and life perspective.

LSD can cause pupil dilation, reduced appetite (for some, it increases), and wakefulness. Other physical reactions to LSD are highly variable and nonspecific, and some of these reactions may be secondary to the psychological effects of LSD. The following symptoms have been reported: numbness, weakness, nausea, hypothermia or hyperthermia (decreased or increased body temperature), elevated blood sugar, goose bumps, increase in heart rate, 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.
