Physical effects of ecstasy
The stimulants in ecstasy actually speed up the activity in the central nervous system. At the same time the hallucinogens in the drug can affect perception, causing things to appear distorted, or things that don't exist to be seen or heard.
There are usually three phases experienced when taking ecstasy:
Coming up: the user may experience tightening of muscles, especially jaw, dilated pupils, visual distortions, nausea or vomiting, strong pulse, increased temperature, confusion and panic.
Plateauing: the user may experience feeling happy, more awake, relaxed, open, confident, talkative and have decreased urine output and increased thirst.
Coming down: the user can feel physically exhausted, depressed, anxious, paranoid, irritable, unable to sleep and the comedown will be more intense if they have taken other drugs, including alcohol.
