Cannabix Technologies Inc. is a leader in marijuana breathalyzer development for law enforcement and the workplace. Cannabix is actively developing breath testing technologies in the pursuit of bringing durable, portable tools to market to enhance detection of marijuana impaired driving offences on roads at a time when marijuana is becoming legal in many jurisdictions globally. Cannabix is working to develop drug-testing devices that will detect Tetrahydrocannabinol (THC- the psychoactive component of marijuana that causes intoxication) using breath samples. These devices would be used to provide detection of THC at roadside and identify drivers under the influence of marijuana. In particular, Cannabix is focused on developing breath testing devices for THC detection that would target recent use of THC, (within a two hour time period at time of testing) in contrast to saliva or urine testing for THC which can be invasive and take a considerable amount of time for laboratory analysis. The devices will also be useful for other practical applications such as testing employees in the workplace where intoxication by THC can be hazardous.
