Is ecstasy a upper or downer?

Answer 1

Ecstasy (MDMA) has some stimulant properties, and therefore one could refer to it as an "upper". Nevertheless, it also has several other effects (feeling of empathy, emotional closeness to others, etc.) which give it the classification of empathogen/entactogen.

Answer 2

It's an upper because of the fact that it is made of amphetamines.
