New York can claim its bagels are the real thing, but in a recent journalistic investigation from the folks at New York Magazine into the purity of street-bought molly — what the courts and scientists call 3,4-methylenedioxy-methamphetamine or MDMA — the city's supply turned out to be less than 100% authentic. Meanwhile, in San Francisco, where "rumor had it" the molly was purer, a home-test kit and then lab data confirmed that all of the purchased substance was the genuine article.

In test-cases back on the East Coast, substances sold as "MDMA" turned out more frequently to be Ethylone, which inspires a weaker euphoria and is related to methylone and butylone, and MDA, an MDMA sibling known for it's faster and "trippier" results.

A California nonprofit run by a couple named Earth and Fire Erowid helped NYMag: They arrange and anonymize testing of molly and other drugs, posting the results at in a database designed to keep clubgoers from becoming hospitalgoers. After the home tests, the couple helped run lab tests to confirm and clarify.

The project itself was prompted by the recent incident at Wesleyan University in Middletown, Connecticut, where 11 students were hospitalized by a drug sold as molly" that, according to police, contained a mix of other chemicals.
