^ Dude that's horrible HR, a blotter can hold at least 2.5 mgs, likely even more... Death isn't the only risk, you also gotta take peoples mental health into consideration as well as hospitalizations. I know bromo d-fly is probably the last thing your gonna find on a blotter but 2.5+mgs of that shit can cause vasoconstriction so bad that it will likely result in a hospitalization, along with a 36 hour nightmare.
If the blotter was layed by some random who doesn't know what they're doing then a single blotter, while it very well not gonna kill someone (although it's possible), can also result in a hospitalization.
Even if the blotter is LSD there is a blotter going around at 732mcs!!! (

This dose can also cause a traumatizing experience and a mental break, imagine a first time user taking one of these blotters which is an equivalent to 10-12 blotters, it's not gonna be a pretty sight
! The average blotter contains around 60-80mcs ...
While it may not be an everyday occurence for something to go wrong with a single blotter it's not outside the realm of possibility and there's no doubt that your risking your life when taking random, unknown blotters. Don't be offended by my post, like I said I've got no problems with you Crashing but this type of advice can get someone hurt.
OP if you don't want to take any risk of adverse effects then don't consume random blotters, if you do at least invest in a reagent test kit or send it in to ecstasydata.org. Even a reagent test kit won't tell you what dose is on the blotter but at least you will know what your taking. Taking unknown dosed blotters is very risky, especially if you don't even know what drug is on the blotter.
Nobody can tell you what's gonna happen if nobody knows the dose or substance, if you want to consume NBOMe or DOx at least order them online from vendors who know what they're doing that way you know the dose and substance you will be ingesting, you will also be saving a fuckload of money compared to buying blotters of someone on the street. NBOMe is rediculously cheap online, as is DOx...
