Customs officials decline to confirm the report, saying only that an American artist entered Norway with a small amount of marijuana that was detected by a sniffer-dog. Norwegian law prevents law enforcement officials from naming suspects.

A customs officer who spoke on condition of anonymity said Thursday that the artist was also carrying more cash than is legally allowed and was subsequently fined 52,000 kroner ($8,600) for the violations.

Snoop Dogg was scheduled to perform Thursday at a musical festival in the southern town of Kristiansand.

The rapper, whose name is Calvin Broadus, has in the past been arrested on marijuana possession.
