Quote of the Day:
MDMA, or methylenedioxy- methylamphetamine, was first patented in 1912 by German scientists looking for a substance to control bleeding. The US military experimented with it in the 1950s and this may have led to instances of it being used recreationally in the US in the 1970s. In 1976, an American chemist, Alexander Shulgin, who became known as the godfather of ecstasy, took MDMA himself as part of a personal investigation of psychoactive substances. Shulgin was an industrial chemist who had personal experience of psychedelics and worked closely with America’s Drug Enforcement Agency. He described the feelings MDMA induced as “an easily controlled altered state of consciousness with emotional and sensual overtones”. In his journal he wrote: “I feel absolutely clean inside, and there is nothing but pure euphoria. The cleanliness, clarity, and marvellous feeling of solid inner strength continued… through the next day. I am overcome by the profundity of the experience.”
