LSD is the best known and most researched psychedelic. It is the standard against which all other psychedelics are compared. It is active at extremely low doses and is most commonly available on blotter or in liquid form.
BASICS EFFECTS IMAGES HEALTH LAW DOSE CHEMISTRY
CAUTION: NBOMes sold as LSD/Acid
Since 2013, some blotter and liquid "acid" being sold in the Americas and Europe contains NBOMe compounds instead of LSD. The NBOMe chemicals can cause strong effects even on a single standard hit of blotter (1/4" (6mm) square). Unlike LSD, NBOMes can cause death. NBOMe compounds are usually bitter while LSD-containing liquid or blotter has only a mild metallic flavor or no flavor at all.

LSD Use On the Rise, 1993


I suddenly became strangely inebriated. The external world
became changed as in a dream. Objects appeared to gain inrelief;
they assumed unusual dimensions; and colors became more glowing.
Even self-perception and the sense of time were changed. When the
eyes were closed, colored pictures flashed past in a quickly changing
kaleidoscope. After a few hours, the not unpleasant inebriation,
which had been experienced whilst I was fully conscious, disappeared.
