LSD Sheet is a derivative from ergot, a fungus that grows on rye and other grains. It was discovered in 1938 and was used in the early 1950s for experimentation by doctors and therapists to treat individuals with mental disorders, alcoholism, epilepsy and terminal cancer. These experiments proved unsuccessful but the interest in LSD grew as reports of its alleged mystical effects peaked curiosity in many. In response to the growing use of LSD, legislators passed laws in the mid-1960s banning the manufacture and use of this drug. However, illegal laboratories and black market dealers were already producing the drug.
