Abstract

Opium poppies grow wild worldwide, and testing for morphine is now highly sensitive. Currently, many authorities worldwide do not pursue urinary morphine concentrations of less than 100 ng /ml. This is because such low urinary morphine concentrations are likely to be environmental morphine identifications (EMIs) and are also unlikely to be associated with pharmacological responses.
