My experiences with insufflated 2C-B were not as bad as people describe, but it hurts a lot and has caused sores abs bloody noses. I heard that diluting it in saline helped, so I tried that. Dear god was that painful. I had a friend that had insufflated it 6-7 times prior, but after that will never insufflate it in any form again. It was just plain miserable.
More to the point, you found 2C-I? I haven't bought any since the pre-WebTryp days. My friend still has it in storage for me somewhere, but I haven't bothered to try to reclaim it. I just remember a lot of people saying that they had developed HPPD after using it in high doses, a claim that disappeared with it until the NBOMEs appeared
