Paul McCartney是否曾經藏毒?

On 16 January 1980, McCartney and Wings went to Tokyo for a series of 11 concerts in Japan. While going through customs at Narita Airport, officials found 7.7 ounces (218.3 g) of marijuana in McCartney's luggage. He was arrested and taken to a Tokyo prison whilst the Japanese government decided what to do.
McCartney had been previously denied a visa to Japan (in 1975) because he had been convicted twice in Europe for possession of marijuana. During the ten nights he spent in prison he made a mental list of all the drugs that are legal, but still dangerous. He thought about the fact that many people are addicted to legal drugs, such as cigarettes, whiskey, aspirin, and valium, but marijuana was still illegal.

HOPE IT HELPS!!
