We report the analysis of poppy seed filling for morphine and codeine content. Concentrations in the range 17.4 to 18.6 micrograms/g (morphine) and 2.3 to 2.5 micrograms/g (codeine) were found in different lots of the filling, which is widely used in baking. The effect of consumption of poppy seed filling on opiate urinalysis results is discussed. Morphine concentrations as high as 4.5 mg/L are reported, with persistence of concentrations greater than 0.3 mg/L as long as 35 h after consumption.
