It became available on the streets in the 1960s, but was soon outlawed. With LSD tablets, it is difficult to tell how much LSD is actually in the blotter. Tabs are often dipped in another chemical agent in order to bind the LSD to the paper. The binding chemical agents can often cause side effects, such as grinding of the jaw and restlessness. Liquid acid is ingested per drop.
Many users prefer liquid acid to tabs because no chemical binding agents are needed.
A Short History of LSD LSD was first synthesized in 1938 by a chemist working for Sandoz Laboratories in Switzerland. It was initially developed as a circulatory and respiratory stimulant. However, no real benefits of the compound were identified and its study was discontinued. In the 1940's, interest in the drug was revived when it was thought to be a possible treatment for schizophrenia. Because of LSD's structural relationship to a chemical that is present in the brain and its similarity in effect to certain aspects of psychosis, LSD was used as a research tool in studies of mental illness.
