A spilled bong landed a pair of young Dunedin men in hot water with police after officers smelled drugs in their vehicle.

Senior Sergeant Anthony Bond, of Dunedin, said officers stopped an 18-year-old man after he performed a poor stop at a stop sign exiting Prospect Park at 7.40pm Tuesday.

The vehicle smelled strongly of cannabis, which prompted a warrantless search.

Officers found 8.2 grams of cannabis and a small amount of LSD.

The 17-year-old passenger admitted to consuming cannabis, but said he had spilled water from a bong in the car.

Both were given a warning for drug use.
