Cops don't do anything to people who are high in public as long as they aren't holding and aren't causing problems. They won't arrest you, they won't do a thing. Especially in Florida. Florida sucks and there's nothing to do but be high, and the cops know this.
Besides that, if you're around cops, you're somewhere you shouldn't be, and if those cops can tell that you're high, you can't handle your shit.
