“…False‐negative screening results can occur if too much time has passed between opioid use and testing or if metabolites are not present in sufficient quantity to be detectible . A number of substances have also been associated with false‐positive immunoassay results for opioid use, including ingested poppy seeds, as well as dextromethorphan, diphenhydramine, quinine, quinolones, levofloxacin (Levaquin), ofloxacin (Ocuflox) rifampin (Rifadin), and verapamil (Calan) . A 2017 study that compared meconium drug screening with maternal urine drug screening to detect opioid exposure among woman‐newborn dyads at birth found that maternal urine drug screen had a higher sensitivity (0.52; 95% CI, 0.39‐0.65) and specificity (0.88; 95% CI, 0.79‐0.97) for the detection of intrauterine opiate exposure compared with meconium drug screening .…”

“…Many opioids can be missed during routine screening, generating significant false-negatives, and it has been reported that screening is also prone to many false-positive results in the presence of poppy seeds and quinolone antibiotics [13,94]. Indeed, poppy seed paste used in foods could lead to positive urine tests for opioids, even if increased cut-off levels are used and different biomarkers are considered for the differential diagnosis, such as the presence of thebaine to ensure justice for each individual [13,95]. Moreover, if an individual is currently taking a lawful medication containing codeine, the test can suggest that he/she has used heroin.…”

“…O século XIX foi marcado por grandes avanços medicinais, pois em 1803 o farmacêutico Friedrich Wilhelm Adam Sertürner conseguiu isolar a morfina da espécie Papaver somniferum. Tal acontecimento foi um marco crucial para o início do processo de isolamento de princípios ativos de espécies vegetais, pois pouco tempo depois no ano de 1819 ocorreram as extrações da quinina e quinidina obtidas da espécie Cinchona spp e, posteriormente a atropina da espécie Atropa belladona em 1831 (PUNDARIKAKSHUDU et al, 2018;OZBUNAR et al, 2019).…”
