A joint University of California, SFO/University of Pittsburgh study has been released which finds "playing violent videogames can lead young men to believe it is acceptable to smoke marijuana and drink alcohol", Gamasutra reports. Reuters is also carrying the story, with some information about methodology available in that piece. From the article: "Brady and Matthews had a group of 100 male undergraduates aged 18 to 21 play either Grand Theft Auto III or The Simpsons: Hit and Run. In the Simpsons game, players took the role of Homer Simpson and their task was to deliver daughter Lisa's science project to school before it could be marked late. In Grand Theft Auto III, players took the role of a criminal, and were instructed by the Mafia to beat up a drug dealer with a baseball bat."
