It's hard to compare 2C-E and LSD. I can even state it more clearly after my trip on 25I-NBOMe (which kind of disappointed me overall but nonetheless it produced LSD-like OEVs because there weren't only OEVs like patterns and things on surfaces but also very realistic visuals forming "in air", this is something I haven't noticed with other psychedelic phenethylamines, I guess only DOTFM gave me a real loss of feeling of time and visuals took control over me, 25I-NBOMe here even seems light compared).
But to the point - the visuals one gets after 2C-E and LSD are different, the kind of euphoria and bodyloading is different. It's like with any group of drugs. You can't really compare opioids with benzodiazepines and they're both depressants, the same goes for caffeine and cocaine etc.
Really? That's tiny, you wouldn't even get a trip out of one tab. You'd need about four for a proper medium-strong experience.
I would bet that it's actually true. The amount of LSD / blotter is lower and lower with years. I remember getting such a weak blotter (at least it cost me 3 times cheaper than normally this person sold it, one good turn deserves another, right?) that I felt absolutely nothing after taking half the blotter, then I added the second piece after an hour because there were clearly no effects but it didn't help a bit. I guess it was some terrible batch. But I still remember times when one blotter set me up good for like 12 hrs.
But there's another strange thing I learned from Erowid: "Threshold 20 ug / Light 25 - 75 ug / Common 50 - 150 ug...". Is there anyone who feels threshold at 20ug or can say that gets a common experience after consuming 50ug?
