There is no truth to this misconception.
Neither ingested psilocybin, nor LSD can be transferred through contact
with someone's skin.
This myth is most likely rooted in the fact
that d-lysergic acid diethylamide (LSD) in its purest form (powder) can
in fact be absorbed into the body through contact with the skin or
mucous membranes such as the nose, mouth, or eyes. Psilocybin/psilocin
also are absorbed through mucous membranes and sensitive skin, along
with other "less pure" forms of LSD.

or Metel), which contain the alkaloid "scopolamine." Certain other
