Mixing Cocaine And MDMA: Side Effects And Risks

Medically Reviewed by Johnelle Smith, M.D. on October 11, 2021

Cocaine and MDMA are both powerful stimulants that are dangerous by themselves and even more so when used together. They enhance and prolong each other’s effects and the consequences can be fatal.

Dangers Of Mixing Cocaine And MDMA

Cocaine and MDMA are often used together because of the popularity they share amongst young people and especially people in club or party settings.

Both drugs are stimulants that increase energy and alertness while producing a sense of euphoria. MDMA has the additional effects of stimulating a person’s senses of empathy and emotional closeness.

Cocaine and MDMA can both have negative consequences when abused individually, and these risks are only amplified when they are taken together.

Why Do People Mix Cocaine And MDMA?

Cocaine and MDMA are often found in the same settings, so using them together is often a matter of convenience.

They are also often used together because they tend to enhance or complement each other’s effects. Further, they also prolong each other’s effects and can reduce the need to take multiple doses of either.

What Happens When You Mix Cocaine And MDMA?

Unfortunately, because these drugs enhance each other’s effects, they also enhance their negative effects and potentially fatal side effects as well.

The side effects for either drug are unpleasant, and only become more so when someone is experiencing them simultaneously.

Even worse, the effects of each drug will be prolonged when abusing them together.

The post-acute side effects of MDMA can last up to a week and will likely be much stronger having been mixed with cocaine.

Risks Of Mixing Cocaine And MDMA

This can be especially true when these drugs are combined with high-energy activities like dancing that cause body temperature and heart rate to increase even more.

  • stroke
  • hypothermia
  • seizures
  • coma

  • sudden death

While it is important to remember that cocaine and MDMA are dangerous every single time they are used — whether together or not — they also pose serious long-term health risks.

Using cocaine and MDMA together can wreak havoc on a person’s heart. Furthermore, not all of the consequences of long-term use are physical.

Cocaine And MDMA Abuse Can Lead To Addiction

If someone is abusing cocaine and MDMA to the point where any of these issues are occurring, they are likely already suffering from a substance use disorder.

Cocaine can be very addictive and using it alongside MDMA or any other drug can become life-threatening.

Fortunately, many addiction centers are now well-equipped for treating polydrug use disorders.
