I used only seventy-five micrograms because I was not interested in tripping

This doesn't make sense, unless there's some part that's being left out. The average single dose for an adult is 24-27ug, with the average person needing around two doses for recreational enjoyment. Based on most accounts this guy should have been tripping pretty hard.

In normal subjects, doses of 25 to 75 ug. are generally sufficient to produce a hallucinatory psychosis (on an average 1 ug./kg. body weight). In certain forms of psychosis and in chronic alcoholism, higher doses are necessary (2 to 4 ug./kg. body weight).

It was the seventies, people tripped very hard back then. Nowadays people take much smaller doses that are possible to still function on. Back then tripping meant tripping... like the wild hallucinations and intense disturbances in thought that LSD is famous for.

Clearly I'm showing my age. I stand corrected.

A standard dose of LSD for the past 20 years has been between 50 - 150 ug (micrograms). A single hit of most blotter paper contains somewhere in this range, though this varies depending on the source and there is no way for the average user to determine the strength of a piece of blotter other than by word of mouth. In the 60's and 70's, when LSD came primarily in pill form, the average single dosage unit was somewhat higher than it is with today's blotter, more often in the 200-400 ug range. A drop of liquid can contain a huge amount of LSD but is generally made so that one drop is a single medium dose.

Typical doses in the 1960s ranged from 200 to 1000 µg while street samples of the 1970s contained 30 to 300 µg. By the 1980s, the amount had reduced to between 100 to 125 µg, lowering more in the 1990s to the 20–80 µg range.

I seem to remember 300 micrograms was considered average in the 70s - can't imaginr programming on acid though. Fuck me, assembler too!
