Andy Roberts - Britain’s Clandestine LSD Chemists

The history of clandestine LSD production in Britain dates back to the mid-1960s, driven by an increasing consumer demand that far exceeded the legal sources. Initially, access to LSD was limited to small amounts leaking from medical research contexts, but unauthorized manufacturing quickly gained momentum as recreational use grew. This rise in illicit production occurred despite limited legal oversight before 1966, when the legal status of LSD only fell under the Poisons Act. Victor James Kapur, a chemist who ran a shop in North London, serves as a primary example of this early clandestine manufacturing. His operation later became linked with broader criminal networks, including a connection that involved the notorious Kray twins. Investigations eventually revealed the existence of these clandestine labs, illustrating the complex intersection of illicit chemical production, counterculture, and organized crime in twentieth-century Britain.
