Breathalyzers have been in use by various law enforcement organizations for a long time now. They have come a long way from being stationary large machines that the police needed to escort DUI suspects to. Modern breathalyzers are small enough to fit in a pocket, accurate enough to get the right reading most of the time, and cheap enough to be bought by civilians and private organizations in bulk. Earlier uses of the breathalyzer were largely in law enforcement, or more particularly, in street and highway patrol. The police have to check whether a citizen is under the permissible level of alcohol consumption. If found over the limit, required action can be taken, depending on the national and state laws.
There is a growing amount of research and development in the making of breathalyzers and other types of drug testing devices. Here are two of the most recent and promising advancements in this field:
The Wearable Breathalyzer
The National Institutes of Health had recently conducted a Wearable Biosensor Challenge, and the winner turned out to be a wearable breathalyzer that was then known as the BACTrack Skyn. It is a simple looking wristband that can accurately measure the blood alcohol levels of a person through the skin, or the person’s transdermal alcohol content. The makers of the device stated that the wristband is not intended to be a complete replacement to current lineup of breathalyzers that police officers use. Rather than that, it is meant to be used by doctors in hospitals to track the patients that have a drinking history. The overall goal of the device is to help patients with alcohol problems cope and move ahead with their treatment.
A team of researchers from the University of B.C. have created a device that might be able to measure the presence of marijuana in a person’s breath. According to the theory, THC, the main intoxicant drug in marijuana, stays in the saliva and blood for twelve hours after intake and can be measures using the device the researchers created. It detects THC in the exhaled breath of a person and could help law enforcement agents control the increasing consumption of the substance in places where it is illegal.
