What is LSD?

LSD is one of the most potent, mood-changing
chemicals. It is manufactured from lysergic acid, which
is found in the ergot fungus that grows on rye and other
grains.
It is produced in crystal form in illegal laboratories,
mainly in the United States. These crystals are
converted to a liquid for distribution. It is odorless,
colorless, and has a slightly bitter taste.
Known as “acid” and by many other names, LSD is sold
on the street in small tablets (“microdots”), capsules or
gelatin squares (“window panes”). It is sometimes
added to absorbent paper, which is then divided into
small squares decorated with designs or cartoon
characters (“loony toons”). Occasionally it is sold in
liquid form. But no matter what form it comes in, LSD
leads the user to the same place—a serious
disconnection from reality.
LSD users call an LSD experience a “trip,” typically
lasting twelve hours or so. When things go wrong,
which often happens, it is called a “bad trip,” another
name for a living hell.
