Hallucinogen
Use
Disorder is
an
addiction
to
hallucinogens,
including
ketamine
(special
K), phencyclidine
(PCP),
LSD
(acid),
MDMA
(ecstasy), mescaline,
psilocybin
(magic
mushrooms),
salvia,
and
many
other
psychedelic
drugs.
Hallucinogens
cause
psychoactive,
mind-altering
effects
such
as seeing,
hearing,
or
feeling
things
that
aren’t
really
there.
Taking
hallucinogens
can
cause
frightening
hallucinations,
disorientation,
poor
judgment,
and
dangerous
risk-taking
behavior.
Physiological
effects
include
elevated
heart
rate,
increased
blood
pressure,
dilated
pupils,
and
often
can
induce
nausea
and
vomiting. Repeated
use
of
hallucinogens
such
as
LSD
or
ecstasy
leads
to
tolerance
and
can
result
in
psychological
dependence.
