A system, comprising:

• a wearable device, the device comprising:
• a blood intoxicant level (BIL) sensor;
• an attaching linker, wherein the attaching linker secures the BIL sensor in proximity to a region of skin of a user for sensing the BIL;
• and
• a communications hub configured to send/receive information to and from the wearable device;
• and
• a non-transitory computer-readable medium in which a program is stored for causing a processor to perform a method comprising:
• receiving, from the user, a plurality of contacts, wherein each contact corresponds to a trusted individual;
• forming one or more sets of contacts from the plurality of contacts;
• identifying a contact set from the one or more sets of contacts;
• triggering a first user alert in the wearable device when data received by the BIL sensor indicates that the user has passed a first intoxicant threshold;
• and
• transmitting a trusted individual alert and a second user alert when the data received by the BIL sensor indicates that the user has passed a second intoxicant threshold, wherein the trusted individual alert is transmitted to all of the trusted individuals in the selected contact set, further wherein the trusted individual alert comprises an indication that the user has exceeded the second intoxicant threshold and a location of the user;
• and wherein the second user alert is a persistent indicator on the wearable device.
