1. A method for informing a user of an intoxication state, comprising:

  • upon receiving an input from the user at a wrist-borne mobile computing device associated with the user, prompting the user to provide a breath sample to a sample receiving module at a first time point;

    at a processing subsystem in communication with the sample receiving module, receiving a breath sample signal derived from the breath sample;

    at the processing subsystem, determining a value of a blood alcohol content (BAC) metric from the breath sample signal;

    at the processing subsystem, generating a predicted temporal profile of the BAC metric for the user over time, based upon the value of the BAC metric and the first time point; and

    transmitting commands, from the processing subsystem to the wrist-borne mobile computing device, that prompt the wrist-borne mobile computing device to display information from an analysis derived from the predicted temporal profile at a display of the wrist-borne mobile computing device, thus informing the user of the intoxication state.
