They were discovered in 1942, at the height of World War II, German soldiers discovered it during a raid in London, England. A simple whiff of a yerb leaf is known to have to same effect as smoking several Marijuana joints. Now illegal in all countries except Russia, its main supplier is the Russian dealer/struggling actor, Dimitri Boris-Doris. After analysing the original leaves found in London, Dimitri, now standing 7ft 2" from getting so high, discovered the ingredients and has since grown his own from his hometown of Mother, Russia.
