it's definitely a love drug & most certainly for friends or lovers to enjoy together. Many moons ago, e's were the big thing in London, most weekends most clubbers were doing smileys, dollars, doves, Mitsubishi, ahh so many, and mainly based with mdma, mdea is also a mix in e.
Now, especially in Spain, Ibiza and other club scene places, pure MDMA is most popular, and it's more of a pure drug.
First effect, the eyes twitch and tighten, although, your sight is much more enhanced with the light effecting your vision. I suppose like a camera lens f.stop is smaller when it has more light.
Next comes the smile, the euphoric feeling & then the freedom, both speech and feeling
Later is the hallucinations, but with all this, mostly is the laughing & sexual enlightenment
Glad you had a good time, YOLO
