BACtrack is an American breathalyzer manufacturer founded in 2001 by Keith Nothacker in San Francisco, California, operating as a division of KHN Solutions. The company worked with the U.S. Food and Drug Administration to establish the evaluation criteria for personal breathalyzers and received the first FDA marketing clearance for a consumer unit in 2004. BACtrack pioneered fuel-cell sensor technology in pocket-sized devices and launched the first Bluetooth-connected smartphone breathalyzer in 2013. The Go is a keychain-format unit with a folding mouthpiece, semiconductor sensor, and a battery rated for 150 tests. Supreme collaborated with BACtrack on the SS18 BACtrack Go Keychain, a working breathalyzer in white with red box-logo branding.
