Thorpe 1939 found that fruitflies Drosophila melanogaster reared on a medium containing peppermint oil would show a preference for this substance as adults, whereas normally-reared flies avoid peppermint oil. The practical applicability of this phenomenon for narcotic detection was tested by rearing Drosophila on a medium containing either marijuana or heroin. When released in a 6 ft. x 1 ft. x 1 ft. screened chamber designed to approximate an open room, flies reared on narcotics showed no tendency to approach them.
