T0:00-Dose taken as soon as I get out of class with 8 mg Ondansetron for nausea. I decide IΒm going to go by myself to run some errands on the other side of town. T0:05-While waiting for the subway I am struck with a sharp pain in my stomach and lower abdominal cramps. It passes after about a minute or so.

Summary
Very limited human data. Reports highlight a steep doseβresponse curve, mild visuals versus cognitive effects, rare bladder discomfort, and pronounced inter-individual variabilityβcareful titration is essential.
Perspectives
“This drug is okay at best. At 30 mg I barely had threshold effects, but the urinary symptoms presented in full force. This time demonstrated that the drug was definitely responsible for exacerbating that state.”

Tolerance
Build-up

Acute tolerance: develops within a single session β the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Acute tolerance appears to build rapidly after one session and decays over roughly 1β2 weeks, consistent with broad psychedelic patterns; exact kinetics for 2CβiP are unknown. Crossβtolerance with other serotonergic psychedelics is expected.
