99. At the latest right after World Word II the US & UK forces discovered how far German chemical companies had advanced in developing a series of Zyklon B derivatives. Among them one could find a kind of LSD and around 60 stuffs which could be utilized in tortures but also to poison enemies who are to be eliminated, weakened or discredited.
Because of the communist menace trying to spread out of the Soviet Union and China, both US & UK made an effort to lure around 1,500 German scientists in spite their obvious participation in crimes and that most of them were convinced nazis. Many of course stayed in Germany and others came back with filled bank accounts to make careers at BASF, BAYER, HOECHST, and several middle sized companies. That's the reason the German leadership in fabricating well calibrated poisons is still unmatched.
With their usage -as powder or spray depending on your targeting plan or victim- you can cause plain stupid behavior, craziness, diminished creativity, physical dis-coordination, extreme fear, and even death.
During my 10 1/2 years living there between August 1982 and April 1993 and because of my outspokenness as an anti-Catholic and pro-American individual, I was targeted several times (and since) by operatives working for a joint venture between the German State and the Vatican City.
Of course -based on my experience and knowing that Germany is desperate in the recent decade for good news around their accomplishments to favor the export of their products- I'm sure that the Argentinian and Brazilian soccer teams were victims of a type of poisoning during breakfast both in Germany 2006 and South Africa 2010. I also give credit to former First Lady Laura Bush when she writes in her newly appeared book Spoken From The Heart about the 2007 poisoning of the US delegation at a G-8 meeting in Heiligendamm.
