The Los Angeles Times editorial board says that Gil Kerlikowske should have checked such sources as the Congressional Research Service before jumping to conclusions. An April report, issued to advise Congress on whether to loosen federal restrictions on medical marijuana, examined studies comparing teen pot smoking in states with and without medical marijuana laws and found no connection between such laws and drug use. "Concerns that medical cannabis laws send the wrong message to vulnerable groups such as adolescents seem to be unfounded," it stated. They also note that there's little evidence that continued criminalization has discouraged teen drug use, but better education might.
