2. T+01:00:00 [intensity]
intensity
± PLUS/MINUS — Threshold — something may be present, but it's right at the edge of perception. A stronger experience would confirm it; otherwise it may be nothing.
3. T+02:20:00 [intensity]
intensity
+ PLUS ONE — Clearly noticeable. You can tell when it began and how it's changing, though its full character isn't apparent yet.
4. T+00:00:00 [note]
Changes were noticed inside the first hour, including degraded handwriting, yet the author found no clear way to gauge the drug's progress. The only distinct effect was auditory: sharp noises seemed to trail a metallic, spike-like after-tone. In a silent room the experience seemed to vanish entirely, prompting the reflection that a deaf person might have judged the material inactive.
