Why Are Police in PA Looking for Green Tongues in Marijuana DUI Stops?

Many drivers across Pennsylvania have reported that police officers checked their tongues for a green coating during traffic stops. While this may seem unusual, it is a long-standing practice used by law enforcement agencies across the U.S. Some officers believe that a green tongue indicates recent marijuana use. As Pennsylvania law enforcement increases efforts to arrest individuals for driving under the influence of marijuana, concerns are growing about the reliability of this method.

The Green Tongue Test: A Questionable DUI Indicator

Many law enforcement officers believe that marijuana consumption can leave a greenish coating on the tongue. While this method has been referenced in police handbooks since the 1980s, its accuracy remains unproven. Checking a driver’s tongue is often just one of several steps police may take to determine impairment.

Additional Signs of Marijuana Impairment Police May Look For:

• Odor of marijuana: Officers may claim that the smell of marijuana inside the vehicle is strong evidence of recent use.
• Nystagmus (involuntary eye movements): Uncontrolled or shaky eye movement can indicate intoxication from marijuana or alcohol.
• Pupil abnormalities: Dilated, constricted, or pulsating pupils may suggest drug use. Officers often shine a bright light to observe a driver’s reaction.
• Coordination issues: Drivers under the influence of marijuana may struggle with depth perception, balance, or performing roadside sobriety tests.

Can a Green Tongue Be Used as DUI Evidence?

Despite its use in law enforcement, the green tongue theory has been widely criticized in courtrooms. Scientific research has not established a direct link between marijuana use and a green coating on the tongue. In fact, a Utah court once dismissed this method as a mere “hunch” that could not be relied upon as legitimate evidence.

Defending Against a Marijuana DUI Charge

Prosecutors rarely base their entire case on the presence of a green tongue. However, police use multiple observations to build their case. A strong DUID defense attorney can challenge these claims and potentially have your charges reduced or dismissed. Your lawyer will focus on key defense strategies, including:

1. Lack of Probable Cause

• Police must have a valid reason to stop and arrest you. If your arrest was solely based on a green tongue, your case could be dismissed.

2. Witness Testimonies

• Statements from passengers, bystanders, or other witnesses can provide critical context and counter the officer’s claims.

3. Challenging Physical Evidence

• Roadside sobriety tests, breath tests, and blood samples can be flawed due to human error or improper testing procedures. A skilled attorney will investigate potential inaccuracies.
