I would have considered myself an experienced psychonaut before the occurrence I'm about to describe, even though I now realize I experienced a lot of things I was completely new to and definitely not expecting.

Ever since my teen years I have wanted to have a psychedelic experience and experience hallucinations. Originally my intention was to get access to LSD but so far I have yet to experience acid. Imagine my excitement when a friend of mine said he had access to blotter.
I chose to try this chemical out only having smoked cannabis and taking the occasional opiate. The most messed up I've ever been before this experience had to be a toss-up between the first time I got REALLY messed up with a blunt by myself or when I smoked Fentanyl....both pretty cool experiences.
Itยs evening at home during a quiet holiday break. I had been planning for a few days to have a trip, most likely with 4-HO-MET, which has been a great ally lately.
I have had experience with a few research cannabinoids, including JWH0-018, AM-2201, and JWH-250. I have also used ecstasy around seven times, cannabis regularly for the last three years, salvia, alcohol, and tobacco.
User Background Information: I am a 26 year old male with post-graduate education. I am 5ย9ย tall, 180 lbs in weight, and am very lean with strong heart function. This will be somewhat important later. I received the compound after I returned from work and was set on testing it immediately.
Previous experience- Old old days (~20 y.a.): lsd, mushrooms, pcp Recent trials: legal RCs such as JWHs, 4-Aco-DMT, 4-HO-MiPT; 5-MeO-DALT and this one- 25C-NBOMe I had previous trialed ~5 times with 300-950 ug administered on blots taken in buccal/lip and submitted a report based on these experiences.
[Erowid Note: Driving while intoxicated, tripping, or extremely sleep deprived is dangerous and irresponsible because it endangers other people. Don't do it! ] Myself, my girlfriend K, and a close personal friend D all ingest approximately 900 ยตg off 2C-C-NBOMe which had been sourced from a European distributor with a...

(25C-NBOMe / ~450ug) - First Experience - "Crazy For Trying" Date: October 18, 2013 Time: 10:30pm-3:00am Drug: 25C-NBOMe Hcl (not complexed) Dose: 400 - 500ug buccal Please note, this was my first experience with this drug although I'm an experienced user of psychedelics in general.
So here i am staring at the computer screen, "do i take it nasally or sublingual with a surficant". no response. friends are here. out of time, this is research anyways right? "i think two of us should go sublingual and two of us should try it nasally".
I planned for a springtime trip with a good friend, M. Iโd taken 1 tab of LSD about 10 days earlier in Canyonlands National Park, Utah. Otherwise, I hadnโt used a serotonergic psychedelic in about 3 months.
I haven't taken anything for about 18 years and my first trip since was with 750ยตg and 250ยตg at t+2.3 taken buccally under the upper lip. My experience in the past is mostly with LSD and MDMA. When I allowed my tongue to touch the blotter there was a slight chemical taste, not really bitter or unpleasant.
(25C-NBOMe/1 mg) Experience: LSD twice in the 90s. MDMA a couple dozen times, starting in the mid-90s and most recently 2 months ago. 2C-B three times, all within last 6 months. No other psychedelics.
400ยต 25C-NBOMe Complexed Blotter - For The Scientist, Not The Shaman This will be two trip reports for the price of one. First with one blotter and then seven days later with two of the same blotters.
about 2 weeks ago i had 7mg of 25c-Nbome and jesus fucking christ that was a bad trip, I will try to explain all that i remember. i brought about 250mg of 25c. I weighed up 7mg on my scale.(i got confused and thought a mg was 100ug). I put the shit into a small line and snorted it, it burnt like fuck.
