4. Experience Timeline


4.1 11:00 AM - Ingestion of 18 mg 2C-I


The user ingested 18 mg of 2C-I at 11:00 AM, marking the start of the experience. The substance was consumed in pill form, and no immediate effects were felt after ingestion.


4.2 11:30 AM - Onset of Effects


The first noticeable effects began at around 11:30 AM, approximately 30 minutes after ingestion. The user reported subtle bodily sensations that gradually increased in intensity over the next 30 minutes. These bodily sensations were described as harsher than those experienced with 2C-B, with a prominent component of nausea. The user experienced a strong urge to vomit, but was able to avoid it.


4.3 12:00 PM - Approaching Peak


By 12:00 PM, the user was approaching the peak of the experience. The nausea gradually subsided over the next 30 minutes. At this time, the user began experiencing visual distortions. The first visual changes included the user's hands becoming partly translucent, appearing aged and wrinkled. Blood vessels under the skin were clearly visible, and the hairs on the back of the hands began to "dance" in response to music, moving in a downward flow like a waterfall.


The user also experienced geometric visual patterns, similar to level 4 visuals, particularly on the walls. These patterns resembled Mayan-style designs, gently oscillating and rotating. Additionally, the wooden computer desk transformed, becoming covered with a holographic layer of wooden spiral patterns that also rotated in sync with the music.


4.4 1:00 PM to 3:30 PM - Peak Experience


The peak of the experience lasted from approximately 1:00 PM to 3:30 PM. During this period, the user reported visuals reminiscent of 2C-B, but with greater intensity than a lower dose (18 mg) and intermediate to the effects of a higher dose (36 mg). The bodily sensations were stronger than those of 2C-B, but the experience was not overwhelmingly unpleasant—though the user described the body high as less enjoyable compared to other psychedelics.


When the user looked at his face in a mirror, he observed a greyish complexion with visible blood vessels, reminiscent of a Sith Lord character from Star Wars: Knights of the Old Republic. The typical serotonergic effect of significant pupil dilation was also present.


An interesting visual experience occurred when a discolored area of the wooden bathroom floor transformed into what appeared to be Mayan religious art. The eyes in the wood of the apartment floor became "all-seeing." The user also encountered a pair of all-seeing eyes in the kitchen, which seemed to judge him, leaving him unsure of whether their gaze was approving or disapproving.


Despite the powerful visuals, this experience was not as introspective as those associated with LSD or psilocybin. The user did report some novel thought associations, such as linking a work colleague's repetitive hand motions with the fluctuations in global political systems, a metaphor reflecting perceived randomness and lack of meaning.


4.5 3:30 PM - Going Outside


At approximately 3:30 PM, the user decided to go outside. By this time, the pupil dilation persisted, but the visual intensity had greatly reduced. The user experienced a pleasant feeling associated with a residual serotonin buzz, which provided a gentle high in both the mind and body.


The comedown began gradually and continued over the next 2 hours. The user reported returning to baseline consciousness between 6:00 PM and 7:00 PM.


5. Conclusion


The 18 mg dose of 2C-I produced a notable psychedelic experience characterized by significant visual distortions, geometric patterns, and bodily sensations. The peak intensity occurred about 1 to 2 hours after ingestion, with visuals being more intense than 2C-B but not as overwhelming as higher doses of the substance. The experience was less introspective than other psychedelics, but it led to some novel associations and metaphors. The comedown was gradual, with the user returning to baseline consciousness by early evening.


This report provides a detailed, structured look at the effects of 18 mg of 2C-I, highlighting both the visual and cognitive effects experienced by the user during the course of the experience.
