Soon, it will be possible to measure one’s drug impairment by simply using a smartphone app. Not only would this make the process of identifying drunk drivers easier, but it would provide a tool for drinkers and drug users to ascertain their own level of impairment in hopes of dissuading them from getting behind the wheel of a car. The technology behind the app is used currently to diagnose neurological diseases such as Alzheimer’s and Parkinson’s. Its accuracy has made it popular within the United States Marine Corps as a training tool for Apache attack helicopter pilots. How Does the Impairment App Work? It works similarly to the horizontal gaze nystagmus test, which police officers use during field sobriety tests to detect jerking movements in a suspected drunk or drugged driver’s eyes when they follow an object from side to side. These jerking motions are called saccades or micro-saccades. Researchers hope to identify the specific saccadic eye motions that correlate with different kinds of drugs to round out the app’s utility. The app is being created in response to the increase in crashes involving marijuana use in recent years. A national survey of 9,000 nighttime drivers found a nearly 4 percent increase in drugged driving since 2007. That study suggests that drivers under the influence of marijuana increase their risk of crashing by 25 percent. Once the app releases, measuring impairment will be as simple as taking a selfie. With such an accessible format, it is hoped that marijuana and other drug users make the right choice before deciding they are okay to drive. In the event that you do drive and get pulled over, Attorney Will Smith has some advice about whether you should consent to a field sobriety test in the video below:

New App Allows Drivers, Law Enforcement to Test Impairment with Ease

Shortly, it may become possible to assess one’s level of drug impairment using a simple smartphone app. This advancement not only holds the potential to streamline the process of identifying impaired drivers but also provides a valuable tool for individuals who use drugs and alcohol to gauge their own level of impairment, to discourage them from taking the wheel while under the influence.

The underlying technology behind this app has been primarily employed for diagnosing neurological diseases like Alzheimer’s and Parkinson’s. Its remarkable accuracy has even led to its adoption as a training tool for Apache attack helicopter pilots in the United States Marine Corps.

So, how does this impairment-detecting app function?

It operates in a manner reminiscent of the horizontal gaze nystagmus test, a test commonly used by police officers during field sobriety tests to detect jerking eye movements in individuals suspected of driving under the influence of alcohol or drugs. These jerking motions, known as saccades or micro-saccades, serve as indicators of impairment. Researchers working on the app aim to pinpoint the specific saccadic eye motions associated with various types of drugs to enhance the app’s versatility.

The development of this app is a response to the growing concern over the rise in accidents involving marijuana use in recent years. A national survey involving 9,000 nighttime drivers has revealed a nearly 4 percent increase in cases of drugged driving since 2007. This study suggests that individuals driving under the influence of marijuana are at a 25 percent higher risk of being involved in a crash.

Once this app becomes available, assessing impairment will be as simple as taking a selfie. With its user-friendly format, there is hope that individuals who have used marijuana or other drugs will make responsible choices and refrain from driving when impaired. However, when someone decides to drive under the influence and subsequently gets pulled over by law enforcement, it’s crucial to seek legal advice and guidance.
