It's not like that.

Roughly speaking, MDMA doesn't exactly create an artificial closeness, it's more like it breaks down artificial walls. The effects can last far longer than the high - if you're taking it in the right setting, with the right intention, etc.

There's a lot to be said for living life drug-free. However, MDMA has genuine therapeutic potential. If a doctor prescribed your friend Prozac, would you say, 'Have you tried not being depressed?' - similar thing. (Yes, some doctors prescribe MDMA.)
