Chemist Olga Nikolaevna Zelenina heads a laboratory at the Penza Agricultural Institute. She is an expert in the biology of hemp and poppy, and is a sought-after expert in legal cases involving narcotics produced from these plants. Last year, she was asked by defence lawyers to give her opinion in a case involving imported poppy seeds. The prosecutors didn't like her evidence though, and now she's in prison accused of complicity in organized drug trafficking."
