How are lsd dosages typically expressed?

In micrograms.

Explanation:

LSD or acid is a hallucinogenic drug which is considered very dangerous as it alternates the DNA and remains forever in the organism of a user. It is therefore possible for short flashes to occur during a lifetime even even if the person is completely clean.

LSD was most popular during the 1950s and 1960s, especially among the hippy community.
