Those who report ingesting MDMA generally describe a wide array of feelings that include euphoria, love, and self-confidence. They also describe an increased ability to feel connected and empathetic towards those around them as well as a heightened ability to speak about vulnerable material. This last part is key to its promise as a treatment for PTSD; healing from traumatic events can require an ability to discuss memories and feelings related to the trauma that can otherwise be too dysregulating. MDMA stimulates the release of neurotransmitters such as serotonin, norepinephrine, and oxytocin which is thought to contribute to these psychological phenomena. It also has a wide array of physical effects ranging from increased energy and heart rate to potentially more dangerous side effects such as hyperthermia, dehydration, sweating, and nausea. While it is considered safer than many other illicit substances, there are cases of people overdosing and having significant health consequences.
