"LSD is initially produced in crystalline form. The pure crystal can be crushed to powder and mixed with binding agents to produce tablets known as "microdots" or thin squares of gelatin called "window panes"; more commonly, it is dissolved, diluted, and applied to paper or other materials. The most common form of LSD is called "blotter acid" - sheets of paper soaked in LSD and perforated into 1/4-inch square, individual dosage units."
I am guessing then that Purple Haze and Orange Sunshine were blotter acid since they were pills? Good recreation in the early 70's, but the greatest danger is that you never knew what is was being "cut" with.
I was given some "MIT clinical" acid, and experienced my first out-of-body experience. I have cleaned up but still really appreciate the Moddy Blues and The Search for the Lost Chord.
