Nevertheless, amaizingly, the California Highway Patrol Driving Under the Influence Enforcement Manual identifies "green tongue" as a sign of cannabis influence. It is also identified as a possible indicator of cannabis use by the National Highway Traffic Safety Administration's Drug Evaluation and Classification Training Program.
The smoke itself does not turn your tongue green, so perhaps the idea is that, for instance, if you are smoking from a joint some amount of unburnt cannabis may find its way into your mouth and the chlorophyll found therein may stain your tongue. Then a green tongue may be a sign of smoking a joint, or drinking green tea or eating celery.

the color of your tongue generally doesnt change. but the cotton mouth associated with marijuana will give it a dried out appearance sometimes with a thick coat of white saliva.
They cannot know for sure, but it is an indicator. When smoking marijuana, the tongue sometimes becomes dry or white. In slang it is known as "having cotton mouth." There are also oral swabs that many officers carry. The swab tests for marijuana. The officer can swab the tongue and get a result right there on scene.
