Can you tell the difference between poppy seeds and morphine in a hair folical test?

Yes, poppy seeds and morphine can be differentiated in a hair follicle test. While poppy seeds contain trace amounts of morphine, the concentrations are typically low and do not produce significant effects or a positive test result for morphine use. Hair follicle tests can detect specific metabolites and differentiate between the two, as morphine from opiate drug use will be present in much higher levels than from consumption of poppy seeds. Thus, a positive test for morphine could indicate drug use rather than dietary consumption.
