Opium – Perhaps the most ancient of the “Plants of the Gods,” plant remains in Europe clearly indicate that opium was being used by people more than 10,000 years ago. And not only was opium the first effective painkiller, it was also employed as an inspiration by composers and poets. Only in the 19th century did it become widely realized as a highly addictive substance. Some have suggested that this “Plant of the God” might also be termed a “Plant of the Devil.”
