Larry King spoke about the legalization of marijuana Wednesday on HuffPost Live. King said he has "always felt" that marijuana should be legal, arguing that it was legally available until the liquor industry intervened, and claiming that it helps sick people. "I know that it helps ill people," he told HuffPost Live's Jacob Soboroff and Alyona Minkovski. "I know it's great used with cataracts. I think it will be legal." King said he thinks that legalization would be "logical" and that marijuana is OK "in moderation." "I don't think you should smoke marijuana and drive," he cautioned.
