MDMA, known as Ecstasy, is a chemical that is usually taken orally as a capsule or tablet. It is a man-made drug that is chemically similar to both stimulants and hallucinogens. It distorts the perception of time and the sense of touch. Taking Ecstasy causes chemical changes in the brain that affect your mood, appetite and sleep. Repeated use of Ecstasy ultimately may damage the cells that produce serotonin, which has an important role in the regulation of mood, appetite, pain, learning and memory. There already is research suggesting Ecstasy use can disrupt or interfere with memory.
