May be addictive to hallucinogens



LSD acts on a part of the brain, the so-called limbic system, where emotionality and the motivation of certain behaviors are localized. This leads to depth psychological access to the subconscious. This has the consequence that the real perception is disturbed. Thinking and feeling are just as massively influenced as the feeling for space and time. The feeling for the limits of oneself is lost.

Hallucinations can be life-threatening under certain circumstances, because the consumption of LSD can lead to overestimating oneself, for example, which makes one feel like one can fly. Depending on the mood before consumption, suicidal thoughts can arise.

So-called horror trips or bad trips are also described in which consumers feel threatened or persecuted. Weeks after ingestion there may be so-called "flashbacks", which in turn can lead to a temporary loss of reality. LSD does not lead to physical dependence.
The effects of LSD occur about 30 minutes after ingestion and last about 6-12 hours. The intensity of the effect depends on the dose taken, the current mood and expectations (set) as well as the external environment (setting). The active ingredient content of the drug on the market fluctuates considerably, so that the effect for the consumer is unpredictable. Fatigue can occur after the intoxication.

Physical and psychological effects of the drug

  • Sweats
  • Disorientation
  • Balance disorders
  • dizziness
  • nausea
  • Palpitations
  • reduced responsiveness
  • Change from
    o body awareness
    o Sense of space and time
  • euphoria
  • Thought leaps
  • Loss of reality with hallucinations (visual and acoustic hallucinations)
  • Schizophrenia-like sensation
  • Anxiety and panic, sometimes fear of death (horror trip)
  • occasional desire for self-destruction with thoughts of suicide

Mixed consumption with other drugs can lead to a mutual reinforcement of the effects.

Effects of continued use

  • psychological addiction
  • Recurrence of the state of intoxication even without drug use = flashback even after weeks and months
  • Psychoses with persistently distorted perception of "getting stuck"


LSD can still be detected in the blood 12 hours after ingestion, and in the urine for 1-2 days. In the hair, the detection is possible much longer.
