By the end of 1992, Balabanova and her colleagues had examined eleven Egyptian mummies, finding nicotine in all of them, cocaine in eight, and hashish in ten; of some seventy-two Peruvian mummies, at least twenty-six had traces of nicotine, sixteen of cocaine, and twenty of hashish; the two Sudanese skeletons both showed nicotine, but not cocaine or hashish, and of ten burials in Germany, eight had revealed the presence of nicotine, but none had any cocaine or hashish content.
