Discovered by Albert Hofmann in 1938, mass manufactured for use in psychiatry by the pharmaceutical manufacturer Sandoz from 1947 and utilised by the CIA in the 1950s, Lysergic Acid Diethylamide, or LSD-25, was banned in 1967 after its widespread adoption by the counter culture. An effective dose of this invisible, tasteless and odourless compound is 20-30 micrograms. Prior to the ban it had been supplied injected in solution, dripped onto sugar cubes like a vaccination against polio and, famously (by Ken Kesey’s Merry Pranksters), stirred into a bowl of Kool Aid. After LSD was banned the severity of being caught in possession, as with other narcotics, was determined by the weight of the prohibited substance found. For this reason and for other practical concerns in the early 1970s many illegal manufacturers opted to distribute doses using perforated sheets of relatively light-weight, absorbent paper – so called ‘blotter’ – that had been immersed in the chemical. These were labelled with increasingly elaborate designs some of which sat within each individual square whilst others spread over a number or even the whole sheet. Such sheets usually adopt the same format: divided into 900 ¼ inch squares. For some the ingestion of such ¼ inch printed paper squares resulted in a significant right of passage that promised some level of profound insight (but instead simply disrupted a capacity for basic perception). However, these tiny paper squares became vehicles for an iconography or branding which, ironically, promoted clandestine activity. Rather than celebrating consumer society, they could be seen to have sought to undermine or circumnavigate it. They also recall (and occasionally quote) late Modernism, specifically: Conceptual art, Fluxus, Minimalism, Pop and Surrealism. The prints presented at NADA follow an invitation to the artists involved to design a sheet of ‘blotter’ (without the active ingredient of Lysergic Acid Diethylamide). The resulting designs have each been reproduced digitally in editions of 100 prints.
