How to almost always be able to tell if someone smokes

[mushypeas]

I noticed that before i started smoking i called it "pot" and now that i smoke i call it "weed"

ive also noticed that in a ton of my friends do the same and i can always tell if someone does by this.

anybody else know this as true?

not realli i call it green i did before i started too maybe its cause i grew up in a green society with a green family
