MDMA makes people feel very friendly and loving, but it has negative effects too. You can become moody or have sleep problems.
After people take MDMA, they might:
- feel dizzy
- have muscle cramps
- clench their teeth
- have a fast heart beat
- have high blood pressure
- feel very hot
This can be dangerous in crowds or on the dance floor where it's already too hot. Once the effects wear off, you could feel sad or nervous for days.
Heavy use of MDMA can give you problems that last a long time. You may feel confused or depressed a lot. Or you might have problems with your memory.
