The ban expected to last for two years.
Custom officials at the Kjevik Airport in Norway discovered the prohibited substance on Snoop Dogg while he was on his way to a music festival.
The 40-year-old’s lawyer said the rapper had no immediate plans to appeal against the ban.
His client could “live with the decision”, he added.
He went on to perform at Norway’s Hove Festival.
In January, Snoop was arrested in Texas after border agents found cannabis on his tour bus. He was later released with a caution.
The rapper is currently on tour and is expected to appear at the Catalpa.
