First-Time LSD Use: The Risks and the Warning Signs

This is not a guide to using LSD, and it does not tell anyone how to. It is what a detox provider sees when a first experience goes wrong, written for the person weighing it up and for whoever is worried about them.

Most first experiences do not end in an emergency room. The ones that do tend to share a small number of features, and every one of them is knowable in advance.

Two things are unknowable to the person holding it, and no amount of care changes that.

Whether it is LSD at all. Substances sold as acid are sometimes something else. The NBOMe compounds are the most frequently reported substitutes and they carry a different, more dangerous risk profile. Someone can be entirely confident about what they took and be wrong.

How strong it is. There is no label and no standard. Two doses that look identical can differ substantially, which is why “it was fine last time” carries less information than people expect.

For what the different formats actually are, see LSD and gel tabs. For why the names are interchangeable, see is LSD the same thing as acid.

A minority of people go on to experience visual disturbances that continue long after use stops — described clinically as hallucinogen persisting perception disorder. It is not common, and it is not something anyone can predict for themselves in advance. It is the outcome people are least likely to have considered.

LSD does not produce the physical dependence that alcohol, benzodiazepines or opioids do, and stopping does not produce that kind of withdrawal. Nobody should be told they need a medical detox for LSD by default.

What people do come in for is the pattern around it — the anxiety or low mood underneath the use, or the fact that acid is rarely the only thing involved. Where alcohol or benzodiazepines are also in the picture, withdrawal from those can be dangerous and does need medical management.
