pure racemic MDMA has very little stimulant effect. street MDMA can feel stimulating because it is either intentionally mixed with caffeine/speed/meth or contains residual precursor from clandestine synthesis.

my major state was one of deep relaxation ... MDMA does not work like Dexedrine ... I feel totally peaceful.

I meant the psychological role in the book - soma as a tool to melt away discomfort or disturbing feelings, not its literal pharmacology.

The street drug Ecstasy is MDMA usually mixed with speed. MDMA doesn't have a stimulating effect.
