Okay, I just want to clear a few things up...
1.) I am not laying any blotter of any kind. I've been dealing with a very legitimate LSD supplier, and being a very experienced LSD user and a responsible person, I test my product and I am 100% sure it is LSD. It's white on white, unperforated, and the chick I buy it from smells funny and talks about the grateful dead a lot.
2.) The reason I am asking this question is because, more than once, people have told me that they flat-out didn't trip off of the blotter. I am 100% sure the hits I've gotten contain LSD (and more often then not, the hits tend to be dosed with a rather heavy hand).
3.) My hypothesis was that the person who was laying this particular blotter was using a medicine dropper to lay it and didn't disperse it correctly. This is white on white blotter, so they definitely didn't use food dye of any sort to check for even distribution.
4.) On the subject of NBOMEs, I am 100% in the camp that says these should never be sold misrepresented as LSD. I had a close friend nearly die, and myself suffered pretty serious problems from being sold NBOMEs misrepresented of LSD.
