Molly is the nickname for what many people think is “pure” MDMA found on the street. This form of MDMA most commonly appears in powder or capsule form. It is a common misconception that MDMA is a safer and purer alternative to ecstasy.
MDMA is a Schedule I substance, meaning that it has a high abuse potential and no accepted medical use. Since MDMA is illegal, it is unregulated on the street, so you can never be sure what drug you are actually taking. On the other hand, ecstasy is usually found in pill form and is generally considered to be less pure than MDMA or Molly, as people who use ecstasy often know that ecstasy is cut with other substances.
