Wow.... went to a friends and took some fentanyl in a form I'd never even heard of. It was on paper that had been torn from a longer strip, printed with stuff that i don't actually remember at the moment. Guy said it was 1600 micrograms, and I'm pretty sure it was actually at least some kind of opiate. I put it under my tongue and got the taste I associate with most opiates, then within 5 minutes could feel it through my head, up until the point that i had a full blown opiate rush, intensely. I was very surprised at the strength and speed that that stamp sized piece of paper hit me. I was actually really talkative and uplifted mentally, kinda like I feel on coke, except exactly the opposite physical effects on my functions and other feelings. I don't think this makes much sense, but either way, it was badass, followed by about 20 mg of hydrocodone a little later. Oh shit I think I'm about to get sick, hopefully it'll pass quick.
