X, or the scientific name MDMA (methylenedioxy-methamphetamine). It is a synthetic, mind-altering drug that acts both as a stimulant and a hallucinogenic. However, research shows that Ecstasy tablets can contain a number of other drugs that can be dangerous when combined, including methamphetamine, ketamine, cocaine, DXM and the diet drug ephedrine, making it very dangerous.

Ecstasy will increase your heart rate and blood pressure. Other physical effects include tremors, muscle cramps, nausea, faintness, chills, sweating and blurred vision. People who use ecstasy are also at risk of dehydration, which may not seem like a big deal, but by interfering with the body’s ability to regulate its temperature, it puts you at risk of dangerous, sometimes fatal, and overheating.

Shortly after taking Ecstasy, you may also feel confusion, depression and severe anxiety—but these psychological effects have also been reported to occur days or weeks after taking the drug.

Ecstasy directly affects the brain chemical serotonin, and how your brain cells communicate with each other. Clinical studies show that Ecstasy can be harmful to your brain and can increase the risk of long-term problems with memory and learning. Taking too much Ecstasy can interfere with the body's ability to regulate its temperature. This can cause hyperthermia and can lead to liver, kidney and cardiovascular failure.
