Abstract
We disclose a drug tracking system and method of use which may be used to screen a subject's bodily waste and to identify the drug the subject has consumed. The system includes a drug that is tagged with a food dye that may be detected in the subject's bodily waste using absorption spectroscopic analysis. The subject consumes the tagged drug and a user obtains a sample of the subject's bodily waste. The user may analyze the subject's urine using an absorption spectroscopic technique. The user may enter the emission spectrum obtained from the absorption spectroscopic analysis into a database that includes the signature emission spectra from multiple food dyes that are used as drug tags. The emission spectra may be compared and the identity of the food dye and its associated drug may be determined.
