MDMA powder is a purer form of Ecstasy. In Addition, the main ingredient in both is MDMA which is a type of methamphetamine. As a result when taken, either drug induces feelings of extreme euphoria. The user also may feel an increase of energy, as well as a lost sense of time and a strong emotional attachment to those around them. Both drugs are available in tablet or capsule form. Furthermore, the purest form of Molly is a crystal-like powder, usually sold in capsules. The effects of either Molly or Ecstasy last between three to six hours.
