Ecstasy drug, which is also known as MDMA, is a psychoactive substance that causes feelings of euphoria, energy, and emotional warmth. However, there are a number of antonyms for this drug, which express the opposite of its effects. These include depression, sadness, lethargy, and apathy, which are all symptoms associated with withdrawal or the come-down after using ecstasy. Other antonyms could include restraint, sobriety, and lucidity, which all represent mental clarity and self-control. While ecstasy can provide temporary pleasure and a sense of connection with others, the contrasting states of emotion and mental function represented by its antonyms provide a stark reminder of why such drugs should be avoided.
