Myth

"Psychedelics are physically harmless by nature, so they're emergency-free."

What's behind it

Classic psychedelics (LSD, psilocybin, mescaline, DMT) do in fact have a favorable physical safety profile compared to many other substances. This gives rise to the myth that no emergencies are possible — which is not true.

What's actually true

  • Bad trips can turn into acute mental health crises with danger to yourself or others.
  • Psychotic episodes with psychedelics are documented — especially with a family predisposition or mixed use with cannabis.
  • Injuries from falls, traffic, or uncontrolled movements while on psychedelics are real emergencies.
  • Mixed use with lithium or other psychiatric drugs is clinically risky (see cluster psychedelics-lithium, psychedelics-ssri).
  • Acute cardiovascular complications are rare, but possible with a predisposition and a high dose.

What follows

Relatively physically safe does not mean emergency-free. Bad trips, psychoses, falls, and mixed-use complications are real emergency scenarios. Trip-sitting, set & setting, and awareness are essential.

Psychedelics are classified in science and harm reduction as “relatively physically safe” — that’s evidence-based. But it does not follow that no emergencies can arise.

Real emergency situations with psychedelics:

  • Bad trip with danger to yourself or others — jumping out of a window, walking into traffic, self-harm
  • Psychotic episode — persistent, even after the effects have worn off
  • Fall injury, traffic accident from distorted perception
  • Hyperthermia with DOI/DOC and some NBOMes
  • Serotonin syndrome with mixed use of MAO inhibitors
  • Seizure with mixed use of lithium

Practical consequences:

  • Set & setting is not “nice to have” — it’s the central safety measure
  • Trip-sitting by an experienced, sober person is essential at higher doses
  • Low starting doses with an unknown substance or a new setting
  • Drug checking — especially with tablets or powders sold as “LSD” (often they’re actually NBOMes or DO substances with a different profile)

In an acute mental health crisis: see emergency scenarios panic-crisis and psychotic-episode. If there’s danger to yourself or others: 112 or the Berlin crisis service (Berliner Krisendienst).
