Psychoactive substances

LSD and psilocybin: risks, distressing experiences and help

About 3 min read

You do not need to label yourself addicted to ask for help after a psychedelic experience. Intense fear or distressing changes afterwards can be a reason to seek professional discussion in their own right.

What classic hallucinogens are

This group includes LSD (lysergide), psilocybin mushrooms, mescaline and DMT. Them is a substances that temporarily alter a person's mood, thoughts and perception: emotions can range from bliss to intense fear. LSD is one of the most potent substances known, producing vivid perception of colour and shape, a slowing sense of time, and sometimes cross-sensory experiences such as sounds being perceived as colours (synaesthesia).

Physical dependence is low — that does not mean "safe"

This is a genuinely important difference: LSD or psilocybin do not become something the body constantly "demands", the way opioids, nicotine or alcohol can. Deaths from an LSD overdose are "virtually unknown".

Real risks: the "bad trip", accidents, mental health

LSD strongly distorts perception: the shape, movement and colour of objects can change, along with a person's sense of their own body; impaired judgement and a distorted sense of depth and time increase the risk of injury.

Mental health is another important factor. There is some evidence that hallucinogens might bring about or trigger a schizophrenia-like illness in people with predisposing factors, although there is little evidence that they cause long-term psychiatric problems for most people. This means the risk can be considerably higher for people with a personal or family history of psychosis or schizophrenia.

Lasting perceptual changes some people report

Some people have reported a condition lasting days or even months after taking LSD — Hallucinogen Persisting Perception Disorder (HPPD): a brief, unexpected recurrence of certain aspects of the drug experience, sometimes called a "flashback". This does not happen to everyone and is not well understood, but it does occur and can be distressing. If something like this happens after use, that is reason enough for an individual medical assessment — even if use does not continue.

"Not addiction" — so no need for help?

No. Learning that physical dependence generally does not develop sometimes leads to the wrong conclusion that "this isn't serious." In fact, other reasons for seeking help are enough on their own: using frequently to escape problems or to "manage" emotions; one frightening, difficult experience followed by ongoing anxiety or perceptual changes; or simply being unhappy with how the use is affecting your life. The need for an assessment does not depend on the question "is this addiction?" — it depends on how the use is affecting you personally.

Questions

Does an enquiry mean an addiction diagnosis?

No. It is a first step towards discussing the concern professionally.

Does research justify self-treatment?

No. Clinical research conditions cannot be transferred to unsupervised use.

Are LSD and ketamine the same category?

Do not equate them: classic psychedelic and dissociative effects differ.
