Is Tobacco Money Tainted?

Here's a recipe for academic controversy: First, find dozens of hard-core teenage smokers as young as 14 and study their brains with high-tech scans. Second, feed vervet monkeys liquid nicotine and then kill at least six of them to examine their brains. Third, accept $6 million from tobacco giant Philip Morris to pay for it all. Fourth, cloak the project in unusual secrecy. At UCLA, a team of researchers is following this formula to produce what it hopes will be a groundbreaking study of addiction. So far, the scientists have proved that the issues of animal testing and tobacco-funded research are among the most contentious on university campuses.
