Our Mission

Our goal is to not only develop cutting edge science and technology
to address impaired driving, but also to champion the national
dialogue about marijuana-impaired driving.

About Us

The Hound® marijuana breathalyzer solves the fundamental safety problem associated with marijuana legalization: How to objectively determine if someone recently used marijuana and therefore could be impaired while driving or working.  Hound Labs, Inc. has created the world’s first field-tested marijuana breathalyzer to measure recent marijuana use in breath. Working with senior scientists, law enforcement, and researchers, the Company developed a patent-pending technology using a combination of chemistry, physics, and engineering. This novel approach resulted in the incredibly efficient and responsive technology required to measure THC (the psychoactive ingredient in marijuana) in breath – a method that is more than one million times more sensitive than the technologies used today to measure alcohol in breath.

The issue of impairment is complicated because there is no accurate device on the market today to measure recent marijuana use. Although measuring THC in blood, urine, or saliva is relatively easy, these types of testing do not distinguish recent use from use days or weeks earlier. However, THC can only be measured in breath for a few hours after smoking and then it disappears. This time period is critically important because it correlates with the window of impairment identified by researchers. The Hound device measures recently used THC in breath, helping law enforcement and employers to ensure safety while also ensuring that responsible users who smoked days or weeks prior to testing will not be arrested or fired for merely testing THC positive.

“As we examined last week, Hound Labs is in the process of testing a breathalyzer that can measure THC content in a user, which, if approved, could wind up helping law enforcement in a big way by getting impaired drivers off the roads and ensuring law enforcement doesn’t arrest non-impaired drivers.”

"From a trauma center perspective, I have seen the terrible, senseless tragedies related to impaired driving," Lynn said. He's seen it from a law enforcement perspective, too, and knows the challenges police officers face when dealing with impaired drivers. ~ CBS News

“..if all goes well (which is the expectation of its CEO Mike Lynn), they’ll be in the hands of law enforcement and interested consumers by late 2016. Clinical testing will involve legal medical marijuana patients at the University of California, Berkeley’s campus…”
~ The Motley Fool

“Other companies have touted the ability to detect marijuana through the breath in products currently in testing, but Mr. Lynn says his product will be the first to give precise measurements in picograms — measurements of one trillionth of a gram — that can be used to determine a person’s current level of intoxication from smoking marijuana.”
~ The Washington Times

"Our ability to measure THC in breath really should shift the national dialogue from one about simply detecting if THC is in someone's body to a conversation where standards can be developed that reflect actual impairment," said Lynn. ~ Fortune

"Law enforcement officers around the country are anxiously waiting on the day when a portable weed breathalyzer becomes reality, so they can stop relying on the scientifically dubious roadside munchies test. Thankfully, one Californian company (Hound Labs) claims to be almost there." ~ Gizmodo

"It's not as if every breathalyzer will be replaced overnight [but] it will completely change the ability to recognize stoned drivers," he says, "[and] our technology also will prevent the wrongful arrest of people who have some THC in their system but are not impaired." ~ US News

"As we examined last week, Hound Labs is in the process of testing a breathalyzer that can measure THC content in a user, which, if approved, could wind up helping law enforcement in a big way by getting impaired drivers off the roads and ensuring law enforcement doesn't arrest non-impaired drivers." ~ The Motley Fool

"Developed at UC Berkeley, trials on Hound Labs' new technology will begin early next year at UC San Francisco. That's when Alameda County sheriff's deputies will begin carrying the prototypes of the firm's handheld device to conduct voluntary roadside tests." ~ San Francisco Chronicle

About Hound Labs, Inc.

Hound Labs, Inc. is a scientific device company that developed the first technology to rapidly, accurately, and inexpensively detect and measure the levels of both marijuana and alcohol in a person’s breath. Dr. Mike Lynn, an ER physician, reserve deputy sheriff, and former venture capitalist and Mr. Kuni Oh, a patent attorney with deep technical background in engineering and science co-founded the Oakland-based company in 2014.
