All About LSD
LSD stands for d-lysergic acid diethylamide. It’s also called acid. It’s a type of
psychedelic drug that can lead to hallucinations. It alters a person's ability to
think and feel. It can cause changes in sensation and emotions.
In its pure state, LSD is a white, odorless powder. It's usually sold in liquid form
or as tablets or capsules. It's often put on absorbent paper. This paper is then cut
into small, decorated squares. Each square is one dose.
LSD is very potent. Small amounts can cause strong effects. These effects are hard
to predict. They usually start 30 to 90 minutes after taking the drug. They are strongest 3
to 5 hours later. They can last for up to 12 hours.
The typical effects of LSD include the following:
Intense sensory experiences (brighter colors, sharper sounds)
Mixing of the senses (colors are heard or sounds seen)
Distorted sense of time and space (minutes can seem as long as hours)
Distorted body image (a person feels as if he or she is floating or being pulled down
The physical effects of LSD include:
Unpleasant and intense
While using LSD, or “tripping,” a person may feel anxiety or fear. The hallucinatory
effects can be unpleasant, such as spiders crawling on the skin. Or they can be so
strong the person feels like he or she is losing control.
Having a bad reaction to LSD and similar drugs is common. The scary sensations may
last a few minutes or several hours. They can be mildly frightening or terrifying.
The user may feel panicked, confused, suspicious, anxious, and helpless.
Usually, the bad feelings go away when the drug wears off. But some people have them
for several days after. Sometimes, these effects can last weeks or months.
Some people can have a flashback. They may have a repeat experience of the effects
days, weeks, or even years after using the drug. The user may see intense colors and
other hallucinations. The flashback can seem pleasant or produce severe feelings of
Flashbacks most often occur in people who used LSD over a long period. But they can
happen in people who occasionally use the drug. Heavy users may develop brain damage,
such as problems with memory and attention span.
LSD's effects vary from person to person. They depend on many factors. These include
the person's size, weight, and health. It also matters how much of the drug is taken
and if it is used with other drugs.
It's not safe to drive after using LSD. Sensory and perceptual distortions may cause
the user to "see" things that impair driving.
If someone has a bad reaction to LSD, seek medical help right away. Stay with the
person until he or she receives care.
