LSD begins its life as a crystal, and from there is distributed in a consumable form. In the 60s, “microdots” (tiny pills) and gelatin pills (window panes). They were often distributed, along with blotter, to buy liquid LSD. Today, blotter paper is the main form in which acid is observed. Although liquid and gel tabs are sometimes encountered as well. Many people who use LSD regularly prefer liquid acid to all other forms because when properly stored, it can last for many years, absorbs quickly, and is easy to effectively split.
