There is a report on Erowid (sorry no time to search for it) of an accidental overdose of like 100 or 200mg of 2C-I which did not result in death or any immediately apparent physical harm. Of course, it still sucked the big one for the guy going through it.
Has anyone else noticed a major decreasing return from 2C-I? I mean, I had my best trip on it at like 16mg the second time I tried it. And then 30-35mg which I tried once was somehow really disappointing, and certainly not twice as strong, at least subjectively. Same batch and everything. It maybe has a long-lasting psychological tolerance, but there were three months or so between those two trips.
/me pats self on back for 1000th post. :D
