LSD (acid)

No matter why you came to this page, either you decided to buy LSD or to use some of the products listed on our website, maybe it’s maybe it’s just curiosity to learn or you are worrying about one of your relatives, we will give you answers and leads about harm prevention in order to limit aggravating factors associated with LSD use.

A powerful hallucinogen, LSD comes in blotting paper (paper soaked with acid), microtip (like a pencil point), sometimes as a liquid.


LSD causes powerful sensory interference, hallucinations, hysterical laughter. Those effects are very intense and difficult to describe and can vary individually.


The up phase and the comedown can be very unpleasant. In those moments, the risk of a “bad trip” is high: dread, panic attacks, phobia, confusional states or even delirious breath or serious and lasting psychiatric accidents.


The effects are very variable. You never know the active substance content, even for little doses. Do not stay alone.
Mixing with certain antibiotics (Rulid®, Josacine®) is particularly dangerous.
