as well as Bangladesh. Poppy seeds are widely used in Kashmir as a topping on various breads, especially kulcha. Poppy seeds, along with tulsi (basil) seeds, are added to beverages such as thandai, sharbat, milkshakes, rose milk, almond milk and khus khus milk. Health effects Eating large quantities of poppy seeds can cause a phytobezoar which can block the bowels, although this is unlikely if the seeds are consumed in moderation as an ingredient in cooked or baked foods. Allergy (type 1 hypersensitivity) to poppy seeds is rare, but has been reported and can cause anaphylaxis. False positive drug tests Although the drug opium is produced by "milking" latex from the unripe fruits ("seed pods") rather than from the seeds, all parts of the plant can contain or carry the opium alkaloids, especially morphine and codeine. This means that eating foods (e.g., muffins) that contain poppy seeds can result in a false positive for opiates in a drug test. However the results provided will not be the same for someone who uses opiates. Morphine levels in poppy seeds range between 4 and 200 mg/kg. According to an article published in the Medical Science Law Journal, after ingesting "a curry meal or two containing various amounts of washed seeds" where total morphine levels were in the range 58.4 to 62.2 µg/g seeds, the urinary morphine levels were found to range as high as 1.27 µg/ml (1,270 ng/ml) urine. Another article in the Journal of Forensic Sciences reports that concentration of morphine in some batches of seeds may be as high as 251 µg/g. In both studies codeine was also present in the seeds in smaller concentrations. Therefore, it is possible to cross the current standard 2,000 ng/ml limit of detection, depending on seed potency and quantity ingested. Some toxicology labs still continue to use a cutoff level of 300 ng/ml. Discovery Channel's MythBusters series episode "Poppy Seed Drug Test" demonstrated that eating both poppy seed bread and poppy seed bagels resulted in both of the hosts testing positive for opiate use, 30 minutes later. To minimize the problems caused by false positives for competitive athletes, the USADA recommends that competitive athletes refrain from eating foods containing poppy seeds several days prior to a competitive event. A fictional example of such a false positive test in popular culture was in the Seinfeld episode "The Shower Head", where the character Elaine Benes was
