Blotter acids, commonly known as LSD, have been around for many decades. Synonyms for this drug include acid, tabs, hits, dots, and paper. LSD is a psychedelic drug that alters the user's perception, mood, and thinking. It is commonly taken by placing a small piece of paper containing the drug under the tongue, where it is absorbed into the bloodstream. LSD is a powerful drug that can have both positive and negative effects on the user, depending on the dosage and individual factors. While it may be used recreationally, it can also have therapeutic benefits when used under medical supervision.
