Just a note, confirming with just one reagent is also not enough. There has been a case of tryptamine being added to 1P-LSD to fool the Ehrlich, and it does not take a genius to do the same strategy with DOx or NBOx. Thus additional reagents should be used to check explicitly for the presence of those, or more ideally, instrumental analytics are preferred.
When I was in high school, the kids knew how to get NBOMe blotter to pop as containing an indole (and therefore fooling some half-baked assays of reagent tests). It instilled a STRONG sense of caution in me, where even a well tested sheet I often won't exceed 4-6 tabs, since I know I've bodied ~7.5mg of 25C-NBOMe before and that is roughly as far as I'm trying to push that possibility. I would advise most people start with one tab or two though, I'm just a fucking freak with that sort of thing.
Oh yes.. : Some potent synthetic cannabinoids (SGT's) have also been found on (mostly blank) papers.
(forgot to mention this)
I just finished smoking my last sheet of this maybe a month ago! I had 50mcg tabs of MDMB-4en-PINACA I put on old blotter I had kicking around so it was easier to dose, and it came out in a far more evenly-distributed fashion than it ever did when I infused to any of a variety of smokeable plants. I did find that 1-3mg was a sweet spot, 4-6 was a lot and 8+mg of MDMB-4en-PINACA smoked in one sitting was world-spinningly nauseating. Before ever touching synthetic cannabinoids, I was the type to smoke 7 full grams of rosin in 2 days without problem, fully functioning, smoking it in a lossless enail setup. That's to say, like I mentioned above, don't do this shit just because I bodied it, I may be a freak in some metabolic manner.
A strip is 10 hits. A sheet is 100 hits. A page is 1000 hits. A Bible is 10,000 hits and that’s a full gram of LSD in 100ug/doses. Yes, the blotter is thicker and/or larger for most higher dose RC drugs. This info is all on Erowid.org, I’ve worked with Dancesafe and The Drug Coalition of America for over a decade while getting GC/MS testing for different drugs from differing supply chains. Also, go try to lay 1mg of LSD on standard acid-free, highly absorbent cotton paper, such as organic 250 GSM stock, perforated into small, usually 0.25-inch, individual tab blotter paper and see how much you’re gonna screw it all up. I’ve also probably done and moved more acid $$$$ than you in my life.
I have ran through 3 separate social circles of acid traffickers who handle the chem side of things too, 2 are nomadic, not one of them used this scheme you're talking about. They always ran a strip as 10, a sheet as 100, a page as 900 (3 sheets x 3 sheets), and a bible as 9,000 (ten pages). Often a gram was broken down per bible, but for the most part a gram would become a half liter of mildly acidified saline that would be broken down into distribution droppers, which would then be moved and turned into smaller consumer-level droppers by suppliers for street level drug dealers. I have no doubts at all that these practices vary as all of this was on the east coast of the US. I'm glad somebody else here like you brought up how exceptionally difficult laying blotter is, I've been working on different techniques for it for uh, half a decade or so? I'm still only mediocre with it tbh. It is crazy what you can fit onto paper though, I could get 8mg of 2C-B, 10mg of methamphetamine, 4mg of etizolam, and at one point something like 12.5mg of DOM onto standard sized tabs. It's fucking nutty what you can do with it, but it takes an absurd amount of patience, observation and an absolutely antisocial amount of obsession on things. I'm sure you also cringe at the thought of how many people don't think to use a level on their drying dishes. I've made some real like "menace to society" uneven shit when I was first starting, thankfully I just self-supply and have a strange obsession with blotter as a medium, I've never participated in trafficking myself. I'd keep quiet about it on BL anyways, there's a known presence of LEOs here.
