These are some problems that MDMA can cause:

You Feel Sick

MDMA can make you throw up. You might also get the chills or the sweats.

You Overheat

MDMA can make your body temperature so hot that, in rare cases, it can cause liver, kidney, or heart failure or even death.

No Appetite

MDMA can make you not want to eat. Over time, you might lose too much weight and get sick.


If you are addicted to MDMA and try to quit the drug, you can become irritable, nervous, or depressed. You can also feel very tired, have trouble staying focused, and have cravings to take more MDMA.
