This is only related in that it's another person incarcerated over LSD, but I've always found this individual and his story pretty fascinating:

The second link discusses Gordon Todd Skinner, who was the informant that facilitated the arrest of Pickard. I don't know how much of that information is accurate, but it's an engrossing read and it paints a horrible picture of what a government informant can get away with.
