Effects of LSD

  • Uncontrollable fits of laughter
  • Delirium

Risks associated with LSD and possible consequences

Psychological problems

LSD users can have a negative experience commonly known as a “bad trip.” This may happen when the user begins to panic and no longer wishes to feel the effects of the drug. A person in such a state should not be left alone.

The initial effects of LSD are followed by an often unpleasant period commonly known as “down.” The following effects may occur:

  • Anxiety
  • Panic
  • Paranoia
  • Fear

Consequences associated with safety and law

Drug possession is illegal. Simply possessing a small quantity can lead to fines and a criminal record. These consequences also apply to people younger than 18. To learn more, consult the Éducaloi website This hyperlink will open in a new window..
