LSD stands for its chemical name, lysergic acid diethylamide, and is commonly called ‘acid’. LSD was invented by Albert Hoffman.
As a street drug, LSD is usually sold as tiny squares of paper with pictures on them. These are most commonly called “tabs” or “blotters”. But it can also be found as a liquid or as tiny pellets. For further information on this drug, please read our blog post, What is LSD?
