Question: 1 tab of acid is how many ug?
Answer: The most common form of LSD is paper blotter divided into about 1/4" squares called tabs. A single tab usually contains between 30 - 100 ug of LSD. Paper blotters are created by taking a sheet of absorbant paper (usually decorated and perforated) and soaking it in a dilution of lysergic acid diethylamide.
