MDMA, commonly known as Molly, is a powerful psychoactive drug known for its stimulant and empathogenic effects. It is often used recreationally in social settings like music festivals or clubs, where it produces feelings of euphoria, enhanced sensory perception, and emotional openness. Molly typically comes in the form of crystalline powder, while yellow molly or blue dolphin x pills are often seen in pill form, which may contain varying levels of purity or additional substances, making their use risky.
