I also worked at a beer distributor and had three cases of assorted beer on the floorboard of my pickup. At the time, I wasn't drinking much ever though. The beer was some just barely outdated stuff I snagged for free for my buddies. It was about 11:30 at night I think.
I show the license and registration but am ordered out of the truck. I say I haven't been drinking and they don't smell alcohol but my eyes are freakin' bleeding! I had been getting stoned and playing video hockey with a buddy. I got pulled over after running him home, next stop was to drop off the beer at another buddies house.
They make me do the whole field sobriety test, shine the light in my eyes and all that and I pass with flying colors. The know I'm stoned though and the cops (another one showed up right away) are pissed because they can't do squat about it! I also had absolutely no weed or paraphanalia on me. I may have even had a little of the "you boys are shit out of luck" attitude! White guy, white area and white cops. You can get away with that.
That's what the field sobriety test is for right? I passed it and must have been pretty much fine to drive. They really should have had no problem with having to just let me go. Guys get screwed having to blow because they've been drinking even though they pass that. So then they blow at just .08% or a fraction higher and are nailed with a DUI. The cops make them blow because they can, when they should be letting them go.
I wouldn't recommend anyone drive after smoking weed if they aren't used to it. A normal stoner type though, is really no danger at all as far as I'm concerned.
