Snoop Dog, Paris Hilton, Nicole Richie, Tara Reid, George Michael, Justin Timberlake -- we know suspect that all of these celebs are big pot heads.  You've seen pics of them all either stoned off their asses, heard the rumors or even seen them passing the bowl.  Add "Blues Traveler" singer John Popper to the list.

He and his best friend were evidently crusing down the street hittin' a little wacky tobaccy when the cops pulled them over.  His friend was driving, but it was Popper's truck -- so they were both hauled in.  His friend also got a ticket for wreckless driving.

Cops said they smelled the odor of marijuana coming from the SUV and found a small amount of pot and a marijuana pipe.   Of course they smoked the rest of it before they got pulled over - who wouldn't?!

Cops also discovered several hidden compartments where they found 14 weapons, a switchblade knife, a stun gun and night vision goggles. The SUV was also equipped with flashing emergency lights, a siren and public address equipment.  (How strange?!)

Popper says he's a gun collector.  LOL!
