2C-E
Aliases: Europa, Eternity, Aquarust, 2ce
Summary
2,5-Dimethoxy-4-ethylphenethylamine (also known as 2C-E, or colloquially as "Aquarust" and "Eternity") is a lesser-known psychedelic substance of the phenethylamine class. It is a member of the 2C-x family of psychedelic phenethylamines, which are closely related to the classical psychedelic mescaline. Like other psychedelics, it is thought to produce its effects by binding to serotonin receptors in the brain, although the precise mechanism is poorly understood.
Perspectives
“It seems I have the misfortune of adverse reactions to 2C-E, what has been touted as a spectacular substance by many. The headspace was unique and enjoyable, as was the visual aspect, but unfortunately my explorations seem to be hampered by the feeling of being acutely poisoned.”
“There was a strange devil-angel pairing. As I was being told of the ecstatic white-light ascent of my partner into the God-space of an out-of-body experience, I was fighting my way out of a brown ooze. She saw the young Jesus at the bottom of a ladder drifting upwards step by step to some taking-off place, and I saw all the funny gargoyles around the base of the ladder surrounded by picnic bunting. For me it was the 4th of July, rather than Easter!”
“This wasn't bouncy or fun but there was a depth there waiting to be explored. I felt as though I was at the door, peeping inside.”
