The White House today lifted a longstanding restriction on medical marijuana research, giving a green light to a growing group of mainstream scientists who are interested in investigating the potential health benefits of pot. Such research will no longer have to undergo review by the Public Health Service, a process ostensibly meant to ensure the use of scientifically valid clinical trials, but in practice has served as a barrier to launching studies. A bipartisan group of lawmakers, and even opponents of legalization, had called for the requirement to be lifted.
