Alpha-methyltryptamine (IT-290 or 3-IT)

AMT is a psychedelic amphetamine-tryptamine first developed in the 1960's for anti-depressant research , although it was never very successful as a prescription antidepressant. Its effects usually last 8-14 hours when swallowed and 3-6 hours when insufflated. Its effects are often characterized as a cross between a psychedelic and an MDMA, with empathogenesis and strong physical stimulation common. One common side effect with both insufflated and oral ingestion of AMT is powerful nausea and associated vomiting.

Price
Rare, but sometimes sold at events for 5-20$ per dose, available from exotic chemical suppliers for 100-150$ per gram, aproximately the same from underground sources

AMT was placed in Schedule I in the United States on April 4th, 2003 through the emergency scheduling procedure. This makes it illegal to buy, sell, or possess without a license.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
