Answer

The acute effects of MDMA have an initial onset of 30 minutes after oral intake and are characterized by anxiety, tachycardia, and elevated blood pressures. Associated symptoms include diaphoresis, bruxism, jaw clenching, paresthesias, dry mouth, increased psychomotor activity, and blurred vision. Within 1 hour, these sympathomimetic effects are replaced by feelings of relaxation, euphoria, and increased empathy and communication. While overt auditory and/or visual hallucinations are uncommon, patients report increased sensory tactile enhancement and mild visual distortions, such as halos. These effects plateau for up to 90 minutes and then diminish over 3-4 hours.

Many users attempt to prolong these effects by taking additional doses of the drug. However, when too much additional MDMA is consumed in a single session, individuals report unpleasant symptoms of autonomic hyperarousal associated with feelings of restlessness, paranoia, and anxiety. Tolerance to the psychoactive properties of MDMA develops rapidly, and the user is unable to restore the euphoric effects with repeated doses. Instead, sympathomimetic effects predominate, placing the patient at risk for cardiovascular instability, arrhythmias, and hyperthermia.

In addition, following the acute effects of MDMA, users often report a 24- to 48-hour period characterized by lethargy, anorexia, and dysphoria. This period of lethargy is known as the blues or colloquially “suicide Tuesday” after weekend ecstasy use and is dangerous because other drugs often are co-ingested to help ease the "crash" after psychostimulant administration.
