Breathalyzers, blood tests and standard sobriety tests can be used by police officers to ascertain to a high degree of accuracy whether a driver has been impaired by alcohol. However, no such measures are available to law enforcement for the purpose of identifying drivers who are under the influence of marijuana. A company based in Quincy, Massachusetts, seems to have found a way to test for marijuana impairment, and the test relies on tears as samples for this test.
Impairment Measurement Marijuana and Driving (“IMMAD”) is working with the Biomedical Forensics Program of Boston University’s School of Medicine to refine how tears can be used to establish the quantity of active cannabinoids within a driver’s body as a measure of how impaired the driver may be.
The research team’s work established that a person’s tears are a good way to identify and measure which particular cannabinoids may be inactive or active. This particular sample is more specific and sensitive when compared to a person’s saliva or breath. The abstract of this research paper was discussed in April at a forensic science conference, and the paper itself will be presented later this year at a virtual conference of the Midwest Toxicology & Therapeutic Drug Monitoring Association.
Sabra B. Jones, a professor at Boston University, worked with Allen Mello, one of her graduate students, last fall and winter to document the efficacy level of relying on tears as an indicator of the magnitude of cannabinoids present in one’s body. The team relied on the understanding that since tears contain a lot more fat/lipophilic contents and since marijuana as well as its compounds are fat soluble, tears would give better test results when compared to one’s breath or saliva, which contain hardly any fats.
Recreational cannabis is legal in Massachusetts, and the research team recruited volunteers who used their own marijuana for the research. Tears and blood samples were then drawn for analysis. Mello conducted this research to fulfil the requirements of a course. The program trains people who would like to work as forensic scientists, and a chemistry/biomedical background is crucial for such forensic scientists, such as those working in crime labs. The research submitted must meet all the requirements of studies published in peer-reviewed journals, and Mello’s work met this criteria. What is left now is to develop the test further so that it can be commercialized.
Once this test method is finalized and validated by the scientific community, it could potentially play a role in the work of cannabis companies, including companies such as Pac Roots Cannabis Corp. (CSE: PACR) (OTCQB: PACRF) (FSE: 4XM).
