With the number of states that have passed recreational marijuana laws, the need to detect stoned drivers has increased. Technology companies have come to the rescue, creating devices to detect whether an individual has recently smoked or ingested marijuana. While the devices are still undergoing testing, one researcher, who happens to be a volunteer officer, has begun field testing.
Like the alcohol breathalyzers that are commonplace, the marijuana breathalyzer detects the active ingredient, THC, in an individual’s breath. Based on the reading provided, an officer will be able to tell if a person has recently ingested or smoked marijuana. However, unlike alcohol, where there have been countless studies regarding the point of impairment, the research in regards to marijuana is lacking.
