If you're waiting around for the DEA to decide to write you a permission slip then you may end up waiting for the rest of your life. The government probably views this drug as the most dangerous one in existence and I'll try to explain why:
MDMA seems to have the power to help people heal psychological wounds and come together despite their differences, but that's a nightmare for a government who rather have populations remain afraid of one another, fighting with one another, and relying on the government to solve their problems. The government sees it's role as manifesting order out of chaos, and if people are not psychologically conflicted and fighting with one another then a day might come when they begin to feel that they can work together to solve problems on their own without the need for nearly as much government supervision.
