Did molly tell you about her sister, methylone? Most people are probably unaware that what they think they're taking as MDMA or molly is actually a chemical called methylone that looks similar in chemistry, except for an extra oxygen particle thrown in there.
The substance known as BK-MDMA, is hard to distinguish from its molly. Even when buying capsule form, methylone can look like off-white crystals that can range in size from a solid chunk to raw sugar granules.

According to one London based DJ, who takes both MDMA and methylone, the latter makes him desire more (similar effect to cocaine), has a worse comedown, not quite as good a high, and leaves your heart racing.
Cops who have been making drug arrests in Miami, are increasingly seeing that the drugs they're collecting aren't MDMA or Ecstasy, but methylone. Previous years had shown a higher percentage of MDMA street seizures but now the tables have turned. More often than not, BK-MDMA has been sold as molly, and drug dealers have been earning quite a profit from a drug that should cost less than its sister.
As drugs become more and more diluted with synthesized lookalikes, it becomes even more important to test what you're taking and know who you get it from, so you don't end up with a bad night on your hands.
