What is Methiopropamine? Also known as MPA and based on the thiophene ring, Methiopropamine is a structural analog of methamphetamine. While much of the discussion surrounding Methiopropamine is new, the drug itself is not. This analog first appeared in 1942.
It is important to note that Methiopropamine is neither an amphetamine nor a phenethylamine, nor is it a functional analog of either class of drugs. The public sale and use of Methiopropamine is has a much shorter history than the drug itself - Methiopropamine was first offered for sale as a research chemical in the United Kingdom back in December of 2010.
While Methiopropamine has indeed been used as a research chemical in the intervening years, the fact that it still falls into a legal gray area has also given some people reason to view it as a legal high. Since 2010, the use of Methiopropamine has been growing in some parts of the world, and it is often used as a recreational stimulant.
The uncertain legal status of Methiopropamine means that some people are sure to use the drug for recreational instead of research purposes. In fact, Methiopropamine has recently been branded as Blow, and a great deal of its use is thought to be recreational in nature.  
Pharmacology of Methiopropamine Methiopropamine acts as a selective norepinephrine-dopamine reuptake inhibitor. Studies show that Methiopropamine is roughly 1.85 times more selective for norepinephrine than it is for dopamine, an important distinction for research purposes.  
Methiopropamine is thought to be about one third as powerful as dextroamphetamine in its actions as a norepinephrine reuptake inhibitor. Methiopropamine is only 20% as powerful as dextroamphetamine in its actions as a dopamine reuptake inhibitor. Methiopropamine's action as a serotonin reuptake inhibitor is thought to be negligible.  
Methiopropamine and Its Metabolism The metabolism of Methiopropamine is similar to that of its analog methamphetamine. The end product of the Methiopropamine metabolism process is thiophene-2 carboloxylic acid. Methiopropamine is excreted in the urine, while Methiopropamine and thiopropamine are excreted renally.  
Legal Status of Methiopropamine
The use of Methiopropamine is not legal everywhere, and it is important for everyone to understand its legal status before seeking the drug or using it. Currently Methiopropamine is currently illegal in a number of European countries, including Germany,
While the United States does not specifically schedule Methiopropamine at this time, it is important to note that the possession and use of the drug may fall under the Federal Analog Drug Act. Specifically, Methiopropamine could potentially be classified as a methamphetamine analog under the Federal Analog Drug Act.
It is also important to note that a number of states have already moved to make Methiopropamine a Schedule I controlled substance. Florida recently gave Methiopropamine the Schedule I classification, making its sale, use and possession a serious crime.
