Two questions: is marijuana a 'drug?', and can it help you get off harder drugs? The AP reports: Three weeks before he was arrested on marijuana and gun possession charges, singer David Crosby told a newspaper he was through with drugs. Crosby, who was to perform Friday in Frederick, told The Frederick News-Post in a mid-February interview that drugs were no longer a part of his life. "I haven't been tempted by that stuff for 15 years. You get past it," he said. The newspaper published the story Thursday. Police say they found an ounce of marijuana, a .45-caliber handgun and a knife in a suitcase Crosby left in a New York hotel room. He was arrested Saturday when he returned to pick up the luggage. "When I really got toasted toward the end of the hard drugs, it made me not want to write," he told the newspaper. "I wasted a lot of time when I could have been making music." Crosby, 62, was a founding member of both The Byrds and Crosby, Stills, Nash & Young.
