Getting a reading of your blood-alcohol content levels is about to become as easy as glancing at your Apple Watch.

The first-ever wearable alcohol monitor made its debut at CES in Las Vegas this week, giving drinkers a new option for keeping track of whether or not they’re fit to get behind the wheel.

LAS VEGAS — Keith Nothacker is living proof that persistence pays off.

Cult_of_Mac_CES_2015 Nothacker is here at the giant International CES gadget show to introduce a key-size version of his pocket breathalyzer — the first personal, police-grade breathalyzer approved by the Food and Drug Administration. Connected by bluetooth to your iPhone, a quick puff into the $49 BACtrack Vio will tell you instantly if you’re too juiced to drive — or take part in any other activity best done sober.

But 13 years ago, Nothacker was fighting the FDA to bring the device to market.
