http://en.wikipedia.org/wiki/Effects_of_MDMA_on_the_human_bodyShort-term experiential effects, which tend to last less than 4 hours, include:
Mental and physical euphoria
A sense of general well-being and contentednessDecreased negative emotion and behavior such as stress, anxiety, fear, and paranoia
Increased sociability and feelings of communication being easy or simple
Increased urge to communicate with others
Increased empathy and feelings of closeness or connection with others[11]Reduced insecurity, defensiveness, and fear of emotional injury[12]
Decreased irritability, aggression, anger, and jealousy
A sense of increased insightfulness and introspection[11][13]
Mild psychedelia (colors and sounds are enhanced, mild closed-eye visuals, improved pattern recognition, etc.)
Enhanced tactile sensations (touching, hugging, and sex)
Effects beginning after the main effects of MDMA have ended, which can last several days, include:
Lowered mood or even depression (comedown) after the effects have worn off
Increased anxiety, stress, and other negative emotions
Residual feelings of empathy, emotional sensitivity, and a sense of closeness to others (afterglow)As you see, if you didn't have all the social effects, it was fake MDMA.
