Police say people who smoke weed have ‘green tongues,’ though there’s no scientific evidence

Police say people who smoke weed have ‘green tongues,’ though there’s no scientific evidence.

From USA TODAY: Police say people who smoke weed have ‘green tongues,’ though there’s no scientific evidence. Police officers across the USA have used the observation as one of several signs to justify probable cause and make arrests in criminal cases, specifically in DUI cases.

Police officers across the USA alleged in some DUI cases that people who recently smoked marijuana had green tongues. One specialized training program taught all around the world has law enforcement look for a “possible green coating”.

However, police point to no scientific studies that show marijuana causes someone’s tongue to turn green. These leads many criminal defense lawyers to consider “green tongue” arrests to be based on junk science.

“If someone is going to be convicted, it should be based on facts proven beyond a reasonable doubt,” said Bradley Myerson, a defense attorney in Vermont. “Green tongue has nothing to do with marijuana ingestion, let alone impairment.”
