Comment Pupillometer (Score 1) 647
we have a similar device that is undergoing field-testing (that is, it is used as a preliminary test for intoxication, but not necessarily admissible in court) in my township: Lower Merion Township, PA. It is called a Pupillometer. It's made by a company called Barenco. See website: http://www.barenco.com/security-products/eyecheck-pupilometer.asp
I personally think that devices like these actually encourage the legalization of drugs, specifically Marijuana because they provide a vehicle of proof for law enforcement to determine intoxicated drivers/pedestrians without placing a burden on hospitals and labs requiring blood tests and time spent analyzing results. If devices like these are proven to be accurate to limits comparable to a PBT (portable breath test), the commonly accepted preliminary standard for determining alcohol intoxication levels, this only provides more compelling evidence for state elected officials to agree with legalization demands.
