o











LSD effects, LSD psychological and physical effects.








The effects of LSD are unpredictable.

The effects of LSD are unpredictable. They depend
on the amount taken; the user’s personality, mood, and expectations; and
the surroundings in which the drug is used.

Usually, the user feels the first effects of the drug 30 to 90 minutes
after taking it.

The physical effects include dilated pupils, higher body temperature,
increased heart rate and blood pressure, sweating, loss of appetite, sleeplessness,
dry mouth, and tremors.




LSD produces strong delusions and visual hallucinations.

Sensations and feelings change much more dramatically than the physical
signs. The user may feel several different emotions at once or swing rapidly
from one emotion to another. If taken in a large enough dose,
the drug produces delusions and visual hallucinations.
The user’s
sense of time and self changes. Sensations may seem to
“cross over,” giving the user the feeling of hearing colors
and seeing sounds. These changes can be frightening and can cause
panic
.

Users refer to their experience with LSD as a “trip” and to
acute adverse reactions as a “bad trip.” These experiences are
long – typically they begin to clear after about 12 hours.

Some LSD users experience severe, terrifying thoughts and feelings,
fear of losing control, fear of insanity and death, and despair while
using LSD
. Some fatal accidents have occurred during states of
LSD intoxication.




LSD : the flasback effect

Many LSD users experience flashbacks, recurrence of certain aspects of
a person’s experience, without the user having taken the drug again. A
flashback occurs suddenly, often without warning, and may occur within
a few days or more than a year after LSD use. Flashbacks usually occur
in people who use hallucinogens chronically or have an underlying personality
problem; however, otherwise healthy people who use LSD occasionally may
also have flashbacks. Bad trips and flashbacks are only part of the risks
of LSD use. LSD users may manifest relatively long-lasting psychoses,
such as schizophrenia or severe depression. It is difficult
to determine the extent and mechanism of the LSD involvement in these
illnesses.
