Companies creating breathalyzers to detect marijuana’s main psychoactive ingredient appear to be rushing to develop their technology as Canada prepares to legalize the drug.
An engineering professor at the University of British Columbia is the latest to create a breathalyzer that she claims can detect the THC levels in the breath of someone who has smoked marijuana.
The handheld device can identify the chemical in a matter of seconds, and will be used to detect drivers who may be under the influence of the drug.
This could revolutionize the way that marijuana is detected, as spit and blood tests are not nearly as immediate.
Companies are hopeful that their devices will be ready by next Spring, when Canada hopes to have the drug legalized.
