Blotters

LSD blotters are small squares of absorbent paper infused with lysergic acid diethylamide (LSD), a powerful psychedelic substance. These blotters are one of the most recognizable forms of LSD distribution because the paper can hold tiny measured doses, often decorated with colorful artwork, symbols, or graphic designs. A single square is commonly referred to as a “tab.” LSD blotters became closely associated with psychedelic culture from the 1960s onward and remain widely discussed in music, art, psychology, and drug policy conversations today.
