"The plane arrived Friday just before 3 p.m. from Toronto when inspectors with Customs and Border Protection thought they smelled marijuana and began a search, the sources said. Trained drug-sniffing dogs helped search the plane, and Bieber was interviewed at length before agents decided to admit him hours later."

If US Customs had found anything they would have charged him with importing pot and seized the plane. He would be in Federal lock up and probably there till after the big game. They have zero tolerance. Even a roach would bring charges and you can bet the media would be all over it.
