MDMA (ecstasy) can induce euphoria and reduce anxiety and depression. It is being studied for potential therapeutic uses for PTSD and cancer patients. While it can provide benefits, it also has risks. Short term side effects include increased heart rate, sweating, and jaw clenching. Long term risks include depression, anxiety, and memory loss. A clinical trial found MDMA-assisted psychotherapy significantly improved symptoms of PTSD in patients who had not benefited from other treatments. However, more research is still needed to fully understand ecstasy's risks and potential medical applications.
