Current drug detection methods, such as blood and urine analysis, are often invasive raise ethical privacy concerns. This study demonstrates that breathing through typical polypropylene-based meltblown cloth face masks is an efficient user-friendly method for collecting drugs from exhaled breath analysis. By using codeine, ephedrine, guaifenesin, chlorpheniramine found in cough syrup model compounds, we these achieved a collection efficiency exceeding 92% the tested drugs. The analysis yielded pharmacokinetic parameters─such half-life (t1/2), time to maximum concentration (Tmax), window─that were comparable those obtained parallel Given increasing demand noninvasive methods due rising abuse of substances like marijuana fentanyl, this expected have broad applications forensic development.
