Cocaine is the most powerful stimulant found in nature. The first step in making cocaine is actually soaking the coca plant in kerosene, gasoline or diesel.
Pure cocaine was first extracted from the leaves of the coca plant by soaking the leaves in kerosene, gasoline or diesel. It was initially cheap and was marketed in a fortified wine in France as early as 1863. Its use is now so widespread that in in Los Angeles, three out of every four banknotes are tainted by cocaine or other drugs.
Surprisingly, after the US, New Zealand has one of the highest cocaine use in the world.
