With marijuana becoming legal in more and more states across the U.S., concerns about road safety have taken center stage.
As regulations regarding how much alcohol can be safely consumed before driving have been hammered into the public eye for years, many worry that newly legalized pot rules need to be paid the same attention.
However, in order for law enforcement agencies to uphold the rules governing marijuana consumption while driving, an easy system to test the amount of cannabis a driver has ingested is necessary.
For that reason, many companies are working to come up with a device that can detect marijuana the way that traditional breathalyzers measure a driver's alcohol level.
Cannabix Technologies Inc., a Canadian-based firm, says it is nearing the final stages of developing a ‘pot breathalyzer". The device is still only a prototype, but once it becomes available for widespread use, it could revolutionize the way that police enforce marijuana laws.
Will It Be Accurate Enough?
While the advent of a pot breathalyzer would be a major step forward for marijuana legalization, experts say it won't be accurate enough to be used on its own at first. The device would detect whether or not a person has THC, the psychoactive ingredient in cannabis, in their system, but probably wouldn't be able to tell just how much.
More Research Needed
So far, there has been no consensus regarding what amount of THC, if any, is safe for drivers. In Washington and Montana, drivers must have less than 5 nanograms/milliliter, though Pennsylvania allows just 1 ng/ml and some other states don't allow any amount of THC at all.
