Sidney Malitz: "In the film which I will now show, there are two monkeys (Macacus rhesus) who have been receiving daily subcutaneous injections of LSD, starting with 1 µg./kg. and gradually working up to very high doses. In the first scene, one animal had received 240 µg./kg. and the other 140 µg./kg. ... The equivalent of the maximum dose of LSD these animals received, in a man weighing 70 kg., would be 16,800 µg. and 9,800 µg. respectively; these are massive doses
Please Note: Personally, I think that it was those who conducted such cruel experiments as these who should be "...sacrificed some time in the near future, and their brains examined" -- RK
