AbstractEcstasy is a drug which is composed of methylenedioxymethamphetamine, or MDMA. Dr. Marcel Koo, a pharmacologist at Hong Kong University, says it "increases the frequency of brainwaves and produces a hyper-arousal state and sensory overload." It causes spontaneous activity in the retina, so users often see after-images or "ghosts" of things seen seconds before, on top of what they see in the present. In addition, the drug causes synesthesia - where colors are heard and sounds seen.
