What Our Patients are Saying A leading indicator of our success is the feedback we get from our patients. Home Health Library. Evidence for the Health Claim Heroin is a derivative of morphine, the active ingredient in opium which is obtained from the opium poppy. Evidence Against the Health Claim Hair analysis is a more accurate means of testing for heroin use as it is impossible for poppy seed ingestion to produce a false positive result.
Conclusion Some organizations have decided not to take any chances with poppy seeds and drug testing. Image Credit: Nucleus Communications, Inc. Ther Drug Monitor. Poppy seed consumption and toxicological analysis of blood and urine samples.

It has also been shown that the alkaloids present in the opium latex may contaminate the poppy seeds as part of the growing process and that a batch of poppy seeds is the combination of multiple fields in one country: all of these factors may explain why there is such variation within batch and between sources of poppy seeds.
However, the muffin matrix greatly interfered with the extraction process. During the extraction process, a fatty emulsion was formed which affected further sample preparation techniques Figure 3. These aliquots were filtered twice prior to being transferred into HPLC vials however when the chromatograms were analyzed for these muffin extractions, no alkaloids were identified. For this reason, it was not possible to include the poppy seed muffins extract results in the comparison between harvested poppy seeds, thermally processed seeds on their own and poppy seeds on the top of bread buns.
In addition, seed portions from three randomly selected sources were extracted and analyzed with the results shown in Table 8. Again, as was established with extractions of harvested poppy seeds there was much variation in the alkaloids identified and in the levels of those alkaloids present, Deuterated morphine was added prior to extraction of the alkaloids from the seeds and percentage extractions were incorporated into the calculations.
Figure 3. Sample tubes containing poppy seed muffin and extraction solvent, post agitation, and centrifugation. Table 8. Comparison of levels of alkaloids identified in harvested poppy seeds, seeds from the surface of bread rolls and seeds heated with no matrix. What was identified from this data was that whether the seeds were heated on the surface of the bread roll or were heated with no bread matrix, the levels of alkaloids if detected were considerably lower than in the harvested seeds.
Koleva et al. When comparing the results from the current work to levels published in the literature Table 9 it can be seen that these findings are in-keeping with those published by Sproll et al.
The work published by Grove et al. However, this could have been due to the sensitivity of the GC-MS instrument employed, the lack of information regarding the presence of other alkaloids present in poppy seeds at this time as the work reported by Grove et al.
The levels of alkaloids identified in the current work are generally lower than those found by Sproll et al. This research has shown that alkaloid variation exists depends on the specific alkaloids, their source and thermal processing.
It was clear from the data obtained in this current work, and from other studies published in the literature, that there is much variation in the levels of alkaloids identified in poppy seeds. This variation can be attributed to a variety of natural parameters, such as weather and soil conditions, but also in the way that the seeds are harvested Lachenmeier et al. Processing methods prior to packaging and even the baking process has been shown to greatly affect the level of alkaloids Sproll et al.
The findings of this study correlate with the studies published in the literature. When poppy seeds are consumed on a bun or roll, it has been estimated that each roll contains 1—4 g of poppy seeds Lachenmeier et al. Assuming that the average salad contains 3—6 g 1—2 teaspoons of poppy seeds and the average bread bun has between 1. This value cannot be used when relating to young children, the elderly or individuals of poor health Sproll et al.
With respect to the values of morphine obtained in this work for harvested seeds, seeds on top of a bread roll and seeds heated with no matrix Table 10 and taking into account the weights of poppy seeds used in a variety of food products mentioned above, the morphine ingested will not exceed the ARfD determined by the EFSA.
Table Comparison of alkaloids identified on harvested and thermally processed poppy seeds. This update related to the detection of morphine, codeine, oripavine, noscapine, and papaverine in poppy seed samples whereas, the previous report related only to the levels of morphine entering the food chain. Codeine values were given in relation to morphine equivalents, using a conversion factor of 0. Noscapine and papaverine were considered in the most recent publication however, the data that was available to the EFSA did not allow for a hazard characterization but they did conclude that the presence of these compounds would not present a health concern.
In relation to the presence of thebaine and oripavine not included in the work of this paper , it was concluded that there was insufficient data to make any assessment. Based on these updated EFSA findings, the presence of the morphine and codeine in the poppy seeds analyzed in this work, would still would still fall below the recommendations outlined. There is also little or no information on packaging of poppy seeds regarding what, if any, treatment has taken place prior to packaging.
Since the ingestion of poppy seeds has been used as reasons for failure of workplace drug testing and roadside drug testing, more should be done to ensure as much information as is possible is available on the preparation methods of the seeds. The datasets generated for this study are available on request to the corresponding author. This work was approved by the Northumbria University Ethics committee.
