Still happening, in 2023 I was sold a sheet of 25C-NBOMe that was allegedly LSD. Damn near killed a man I was in love with at the time, thankfully the plug was familiar with me and knew to get my money back by the next day. The fool was selling to me straight from his bedroom, I just let him know I'd be waiting there for the money and it showed up. He claims that the other 9 sheets were all purchased by one guy who was "eating them up like candy". They were double-sized tabs of mickey mouse wizards on a tie-dye background, with a ninth of an image of the disney castle on the background. It was obvious that the blotter was printed and perforated as a full page, and then broken down.
Edit: This page was picked up in Massachussetts a couple of years ago. Outside of a vendor notorious for moving things in agar tablets, I've ony seen two other N-Benzylated drugs being produced, some 25B-NBOH crystal, as well as those infamous 25E strawberries.
