I want to try molly once in my life, but i'm afraid of the side effects. what does it do?

"molly": A molly is the purest form of ecstasy (mdma), a recreational drug used for increased energy & partying. Best to avoid such drugs altogether & get your highs from good friends, family, interesting activities. U don't need drugs to have fun. Side effects r not worth the risk.

We can't know: Molly is an unregulated street drug. Anyone could put literally anything into pill form and call it molly. There is no way to know what you are taking, nor what its effects might be. It could be mdma, it could be lye, it could be ricin, it could be dust from a shelf.
