Well then he wouldn't even get high at all and would be bummed out the rest of the evening. Even if its NBOMe he can still have a damn good time as long as hes not taking 10 of them, which based on the questions it doesn't sound like he is. There are ways to know if you have NBOMe or LSD based on the taste of the blotter if you really want to get an idea of what you got.. but Id just keep it under my tongue and ride out and enjoy whatever I got.. He also just says he got a blotter, not that he knows what it is.
Why? I don't understand this train of thought. Christ. "If its not LSD fuck it its useless" "throw your money away" "you cant have any fun on anything but LSD" 8(
I admittedly don't have a vast experience with either compound spanning years on end but my recent 25i-nbome experience was one of my all time favourite experiences.. it was intense as hell, uplifting, euphoric, absolutely no anxiety or paranoia, and the visuals were absolutely stunning.. and the colours that were painted over the world on the come down were absolutely breathtaking and beautiful, I saw ones with my eyes closed that Ive never seen before. I loved the experience very, very much.. to say to just throw away the blotter if its not LSD is completely absurd to me.. at least figure out what you're taking and then take the proper precautions with it (ie, not taking 10 hits if you know its NBOMe).
