[For more, see video cross-posted at NewsBusters.] CBS This Morning journalist Barry Petersen on Monday offered a puff piece on legalized pot in Colorado, displaying no skepticism about health effects. Instead, he happily explained that "more than 60,000 gathered to party for 4/20. In marijuana lore, the day in April to celebrate all things pot." Petersen noted that the convention includes "an actual trophy for the best pot." He informed viewers that the award went to "a Denver-grown variety called Ghost Train Haze." The entire story contained zero mention of any downside to increased pot use, despite the just-released study concluding that even casual marijuana use may damage your brain.
