What is the worst thing that could happen if someone took two mollys?

Taking two molly (MDMA) pills can significantly increase the risk of severe side effects, including overheating, dehydration, and serotonin syndrome, which can be life-threatening. The higher dose may lead to anxiety, panic attacks, or dangerous changes in heart rate and blood pressure. Additionally, the purity and dosage of the pills can vary, increasing the chance of overdose or harmful reactions. It is crucial to seek immediate medical attention if any severe symptoms occur.
