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.
