This photo was posted Wednesday night by Reddit user rnycthrowawa. It shows three hits of Molly after being tested for purity.
The black smudge is MDMA, or "Molly" as it's better known, purchased from The Silk Road, the online drug market recently seized by the FBI.
The FBI have noted the surprisingly high quality and purity of the drugs that were being sold on the Silk Road.
According to law enforcement, from 2011-2013, there were 1,229,465 transactions on the site. 70 percent of which were typically very pure and high quality drugs.
The user also listed several resources for users who worry about purity of newer Molly coming in post-Silk Road closure.
Online drug resource site Erowid.org has a guide to testing Molly with quick examples of what could cause a change in color.
A BuzzFeed Facebook commenter pointed out a concern that many drug users have following the FBI's seizure of The Silk Road.
