LSD stands for lysergic acid diethylamide. It is an illegal street drug that comes as a white powder or clear colorless liquid. It is available in powder, liquid, tablet, or capsule form. LSD is usually taken by mouth. Some people inhale it through the nose (snort) or inject it into a vein (shooting up).
Street names for LSD include acid, blotter, blotter acid, blue cheer, electric Kool-Aid, hits, Lucy in the sky with diamonds, mellow yellow, microdots, purple haze, sugar cubes, sunshine tabs, and window pane.
LSD is a mind-altering drug. This means it acts on your brain (central nervous system) and changes your mood, behavior, and the way you relate to the world around you. LSD affects the action of a brain chemical called serotonin. Serotonin helps control behavior, mood, the senses, and thinking.
LSD is in a class of drugs called hallucinogens. These are substances that cause hallucinations. These are things that you see, hear, or feel while awake that appear to be real, but instead of being real, they have been created by the mind. LSD is a very strong hallucinogen. Only a tiny amount is needed to cause effects such as hallucinations.
LSD users call their hallucinogenic experiences "trips." Depending on how much you take and how your brain responds, a trip may be "good" or "bad."
A good trip may be stimulating and pleasurable and make you feel:
A bad trip can be very unpleasant and frightening:
The danger of LSD is that its effects are unpredictable. This means when you use it, you do not know if you will have a good trip or a bad trip.
How fast you feel the effects of LSD depends on how you use it:
LSD can harm the body in different ways and lead to health problems such as:
Some LSD users have flashbacks. This is when parts of the drug experience, or trip, return, even without using the drug again. Flashbacks occur during times of increased stress. Flashbacks tend to occur less often and less intensely after stopping use of LSD. Some users who have frequent flashbacks have a hard time living their daily life.
LSD is not known to be addicting. But frequent use of LSD can lead to tolerance. Tolerance means you need more and more LSD to get the same high.
Treatment begins with recognizing there is a problem. Once you decide you want to do something about your LSD use, the next step is getting help and support.
Treatment programs use behavior change techniques through counseling (talk therapy). The goal is to help you understand your behaviors and why you use LSD. Involving family and friends during counseling can help support you and keep you from going back to using (relapsing).
As you recover, focus on the following to help prevent relapse:
Resources that may help you on your road to recovery include:
Your workplace employee assistance program (EAP) is also a good resource.
Call for an appointment with your health care provider if you or someone you know is using LSD and needs help stopping.
