With the recent legalization of marijuana in many states, I have noticed, more and more, an old claim - that smoking marijuana makes users tongues turn green.
Is this true and if not, where did this tale come from?
Apparently, Law Enforcement Officers are checking the tongues of drivers looking for a green tongue as an indicator of marijuana use.
I can't find any Police Department that has a written policy on this but it seems to be prevalent throughout the United States. There are numerous criminal defenses that indicate that the officer used it as a basis for an arrest. Hopefully the fact that people are being arrested and jailed based on this is enough to make this a notable claim.
