Naphyrone (nrg-1) being sold over internet as “pond cleaner”

May 30, 2010, 2:03 pm

In the wake of the recent reclassification of mephedrone (4-methylmethcathinone) in Britain as a class B drug, new chemicals — many apparently manufactured in China — have rushed to fill the void.  According to press reports, the most prevalent of these is naphyrone (nrg-1), which is sold over the internet where it is often labelled as a “pond cleaner“.

Unfortunately, almost nothing is known about the pharmacology or toxicology of this drug.  According to Wikipedia, naphyrone (nrg-1) is a derivative of pyrovalerone, a stimulant that blocks re-uptake of norepinephrine, dopamine, and serotonin.  Therefore, it would be reasonable to anticipate sympthomimetic effects after ingestion of naphyrone, as well as the possibility of serotonin syndrome. Given the lack of knowledge concerning naphyrone, this drug has the potential to become very dangerous.

A correspondent on Erowid reported that after snorting a substance sold over the internet as naphyrone, he experienced sympathomimetic signs and symptoms without any accompanying psychogenic or emphathogenic effects.  His conclusion: “not worth trying again”.
