LSD Addiction

LSD, D-lysergic acid diethylamde, also commonly referred to as ‘acid’ is a potent synthetic hallucinogen. A Schedule I drug under the Controlled Substances Act, it is illegal in the USA because of its potential for abuse, dangers, and because there is no accepted medical use for the substance. Its original form is a white, clear crystal that can be crushed into a powder and dissolved, though it is found now in a variety of forms including tablets, sheets of paper laced with the substance, liquid form, capsules, sugar cubes and more.

LSD is a powerful hallucinogen the effects of which last up to 8 hours. It affects the emotions of users as well as their sensory perception, and can lead to dangerous hallucinations and psychotic symptoms.

Important Dates in the History of LSD

According to a report from the University of Maryland, the history of LSD started in a Swiss lab in 1938.

  • 1938: LSD first synthesized by a chemist named Albert Hoffman. At the time, the chemist and his lab, Sandoz, were researching possible therapeutic value of the drug as a circulatory and respiratory stimulant but their research was discontinued when it was found to have no such help.
  • 1943: Hoffman discovered the hallucinogenic properties of LSD through accidental ingestion and studies began to determine its effectiveness in helping treat schizophrenia and other mental illness.
  • 1947: Sandoz markets LSD under the name Delysid as a multi-use cure for many psychiatric illnesses from schizophrenia to alcoholism.
  • 1948: LSD was introduced to the US.
  • 1940s through 1970s: LSD researched extensively; during this time it became a drug of abuse by psychiatric and medical professionals who shared it with their friends.
  • 1960s: Acid became a part of the hippie subculture, was used casually and often.
  • 1970: Controlled Substances Act in USA places LSD as an illegal, Schedule I drug.
  • 1980s: Use of LSD in psychotherapy was discredited, and scientific study of the drug ended as prohibitive legislation worked to stop its abuse because of its potentially dangerous qualities.

Effects of LSD


LSD is a powerful hallucinogenic drug that comes in a variety of forms.

As it is a hallucinogen, the major effects of LSD relate to its perception-altering abilities. According to the University of Hawaii, the effects of acid take 30 to 45 minutes to be felt, and last between six to eight hours, while the University of Maryland reports that they may last up to 12 hours. The drug’s hallucinogenic effects are caused by a disruption of the interaction of serotonin, a neurotransmitter in the brain, and nerve cells. Serotonin has a role in many important processes in the body, such as control of behavioral, perceptual, and regulatory systems and the detection of external stimuli from all over the body. There are several short and long-term effects of LSD.

Short-term Effects of LSD:

  • Physical Effects:
    • Dilated pupils
    • Raised body temperature
    • Rapid heartbeat, elevated blood pressure
    • Increased blood sugar
    • Salivation
    • Dry mouth
    • Tingling fingers and toes
    • Weakness
    • Tremors
    • Palpitations
    • Facial flushing
    • Chills and goose bumps
    • Sweating
    • Nausea
    • Loss of appetite
    • Dizziness
    • Blurred vision
    • Sleeplessness
  • Psychedelic Effects:
    • Visual hallucinations (can be flashes of color and light, geometric designs, distortions of reality, or even completely new images)
    • Intensification of smells and sounds
    • Sense of heightened understanding
    • Distorted sense of time
    • Distorted perception of body
    • Synethesia (blending of sensory perceptions, hearing colors and seeing sounds)
    • Quick changes in emotions, can feel euphoric then quickly change to fear or sadness

Long-term Effects of LSD:

  • Drug-induced psychosis: Some individuals are affected by a distorted ability to think rationally, understand reality, or communicate with others after taking the drug. This condition can last for years.
  • Hallucinogen Persisting Perception Disorder: More commonly known as flashbacks, some users feel the sensory distortions produced by LSD long after taking the drug. This can be very dangerous, especially depending on the situation you are in at the time.
  • For people with pre-existing psychological conditions, LSD can result in prolonged psychotic states and can aggravate the symptoms of the pre-existing condition.
  • Chronic use of LSD can cause depression, violent behavior, or a distorted perception of time.

Dangers of LSD

According to Brown University, the most common dangers associated with LSD result from ‘bad trips’. A bad trip on LSD includes a variety of psychological symptoms that can persist for a good part of the drug’s duration, which is up to 12 hours.

Symptoms of a bad trip include:

  • Intense anxiety
  • Panic
  • Terrifying thoughts and feelings
  • Despair
  • Fear of losing control, losing one’s identity
  • Fear of death, fear of disintegration into nothingness
  • Paranoia
  • Rapid mood swings
  • Violent or hazardous behavior (especially dangerous, can lead to accidental death, suicide, homicide, or self-mutilation)
  • Possibility of seizure

While these are the symptoms of a bad trip on LSD, it is possible to feel any of these symptoms at some point while the feeling the drug’s effects. It is very dangerous to operate cars or machinery while on acid.

LSD Abuse

A report by The National Drug Intelligence Center shows that LSD abuse is more common among males than females, and is most common among twelfth grade students than any other age group. The data also shows that white Caucasian males are the predominate LSD user group entering hospital emergency departments for LSD-induced symptoms.

Developing Tolerance to LSD and LSD Addiction

Though it has its share of dangers, according to the National Institute on Drug Abuse LSD is not considered an addictive drug because it does not produce compulsive drug-seeking behavior. While that is true, LSD tolerance does develop over time meaning that users who take the drug often will have to increase their dosage to achieve the same state of intoxication that was previously achieved. Tolerance is dangerous, as it results in high levels of LSD in the body. In addition, as individuals take higher doses of LSD the effects of the drug become more unpredictable.

The University of Hawaii reports that while physical dependence on acid does not develop, it is possible to be psychologically dependent on the drug. Individuals who take it often may feel like they need it to function and will feel anxious and panicky without it.

Treatment at Rehab Centers for LSD Addiction

Due to the fact that LSD is not really addictive and that there are no withdrawal symptoms associated with stopping use of the drug, treatment at LSD addiction rehab centers is more psychological than physical. As LSD and others write, the need to get treatment for LSD addiction arises once tolerance, and possibly dependence, develops. At that time it is clear that an individual is taking LSD too often, and that its effects are getting more and more dangerous.

Rehab centers for LSD addiction focus on behavior modification and psychological treatment. Individuals who are struggling with an LSD abuse and addiction problem will be taught other ways to relax and to spend time previously spent high on LSD. During treatment, counseling and more in-depth psychological treatment may be necessary as some individuals take LSD as a means of self-medication for depression and other conditions. Once they stop taking the drug, the symptoms of underlying disorders may surface and further treatment would be addressed at that time.

Another possible factor in the treatment of LSD addiction is the possibility that LSD abuse has led to paranoia or the development of other psychological conditions that were not previously present. This would also require the appropriate treatment and would be addressed once discovered.
