This passage from Wikipedia is infinitely funny to me:

DMT has a rapid onset, intense effects, and a relatively short duration of action. For those reasons, DMT was known as the “businessman’s trip” during the 1960s in the United States, as a user could access the full depth of a psychedelic experience in considerably less time than with other substances such as LSD or psilocybin mushrooms.

“Have you always wanted to have a transcendent psychedelic experience but just could never fit it in to your busy schedule? Now you can, with DMT™! Ask your dealer about it today!”
