Abstract
The drug tracking system may be used to screen a subject's bodily waste and to identify a drug the subject has consumed. The system includes drug tags which include a one or more food dyes, each detectable in a subject's bodily waste using photographic or absorption spectroscopic analysis. The system may further include a database in which is stored the spectral signature of each drug tag and the unique drug associated with each drug tag. A spectral analysis obtained by analyzing a bodily waste sample may be entered into the database. The database may include instructions for comparing the spectral analysis to the spectral signature of each drug tag. The instructions may further report the unique drug associated with a drug tag which has a spectral signature matching the spectral analysis.
