Pharmacology
editMeOPP is anecdotally said to induce significantly less anxiety than similar piperazines, and is usually taken at doses between 120–200 mg. However it is often mixed with stimulant piperazine derivatives such as benzylpiperazine (BZP) for a combined effect.
MeOPP has been found in vitro to inhibit the reuptake and induce the release of the monoamine neurotransmitters. This is a mechanism of action shared with drugs of abuse such as amphetamines, and MeOPP produces somewhat similar effects although it is much less potent and is thought to have relatively insignificant abuse potential.[1] Piperazine derivatives such as trifluoromethylphenylpiperazine (TFMPP) have also been shown to exert a major part of their mechanism of action as nonselective serotonin receptor agonists, and MeOPP has also been demonstrated to act in this way.[2]
Legal status
editFinland
editScheduled in the "government decree on psychoactive substances banned from the consumer market".[3]
New Zealand
editBased on the recommendation of the EACD, the New Zealand government has passed legislation which placed BZP, along with a number of other piperazine derivatives into Class C of the New Zealand Misuse of Drugs Act 1975. A ban was intended to come into effect in New Zealand on December 18, 2007, but the law change did not go through until the following year, and the sale of BZP and the other listed piperazines became illegal in New Zealand as of 1 April 2008. An amnesty for possession and usage of these drugs remained until October 2008, at which point they became completely illegal.[4]
United States
editMeOPP is not scheduled at the federal level in the United States.[5]
Florida
edit"Methoxyphenylpiperazine" is a Schedule I controlled substance in the state of Florida making it illegal to buy, sell, or possess in Florida.[6]
