There is a basis in fact and theory that the Roman Empire fell, in part, due to Lead Acetate (AKA sugar of lead) being used as a sweetener. As far as I know, the bad effects of lead are well established, and the use of tetra ethylated lead as anti knock additive in car and aviation has endured in the face of solid science = lead is toxic. The oil and auto business bribed regulators to ignore the science, much like the tobacco bribe industry. I use the term 'bribe' in the true sense, https://en.wiktionary.org/wiki/bribe, versus the political sense where 'lobby' is preferred. https://en.wikipedia.org/wiki/Lobbying There is also the Tammany Hall origin - I will meet you in the lobby with a bag of $$, which some say has been done in Congress in those bad old days.
