Abstract
The present disclosure describes a toilet apparatus for detecting a drug marker in a urine sample. The drug markers are fluorophores each of which emits a unique fluorescence spectrum. Accordingly, the toilet does not detect the drug but rather, the drug marker. The user consumes a drug composition which includes a drug and a fluorescent drug marker. The user urinates normally into the toilet and fluorescence spectrometer within the toilet analyzes the urine for drug markers based on their unique fluorescent spectra. Computer software associated with the toilet identifies, and in some embodiments, quantifies the fluorescent spectra by comparing the detected spectra to known spectra of fluorescent markers associated with the drug.
