MDMA
SUBSTITUTES
Some of the drugs that
are in pills that are supposed to be pure MDMA have effects that are very similar or overlap with those of Ecstasy.
Methylone is one of the "bath salts" (see the "Stimulants"
chapter) because its struc-ture
resembles cathinone (its chemical name is 3,4-methylenedioxy-N-methylcathinone). However, its neurochemical effects resemble those of MDMA. It preferentially
releases serotonin, but also dopamine
and norepinephrine, and users find its behavioral effects similar to MDMA. Its toxicity is also
similar to MDMA, and multiple overdose
deaths caused by methylone have been reported in the
scientific literature around the world. The pattern of toxicity is the same,
with stimulation of the sympathetic nervous system, high body temperature, and the cascading organ failure
associated with serotonin syndrome.
Little is known yet about its long-term effects, although some preliminary reports indicate that it does not cause long-term decreases in serotonin like those caused
by MDMA. However, there are only a
few research reports out, so it is early to conclude
much about its long-term effects.
The piperazine drugs (mCPP, TFMPP, BZP) are another
group of drugs that have appeared
increasingly in pills that are supposed to be MDMA. These aren't exactly MDMA-like, although there is some overlap in what they do. Each is a little different.
BZP is like a stimulant: it causes stimulant-like behaviors in rodents and
increases the release of dopamine and
to a lesser extent serotonin. It also has properties common among addictive drugs in animal tests. TFMPP
and mCPP are more serotonin selective
and have been used to assess serotonin function in research laboratories for many years. Both release serotonin but
have hallucinogen-like behavioral
actions that probably reflect a stimulation of serotonin receptors. The combination of BZP and TFMPP most closely resembles the effects of MDMA. TFM PP or
mCPP alone resemble hallucinogens
more than MDMA and can cause severe anxiety, hallucinations, and sympathetic
nervous system stimulation.
