On campuses nationwide, professors and administrators have passionately debated whether their universities should accept money for research from tobacco companies. But not at Virginia Commonwealth University, a public institution in Richmond, Va.

That is largely because hardly any faculty members or students there know that there is something to debate  a contract with extremely restrictive terms that the university signed in 2006 to do research for Philip Morris USA, the nation’s largest tobacco company and a unit of Altria Group.

The contract bars professors from publishing the results of their studies, or even talking about them, without Philip Morris’s permission. If “a third party,” including news organizations, asks about the agreement, university officials have to decline to comment and tell the company. Nearly all patent and other intellectual property rights go to the company, not the university or its professors.

“There is restrictive language in here,” said Francis L. Macrina, Virginia Commonwealth’s vice president for research, who acknowledged that many of the provisions violated the university’s guidelines for industry-sponsored research. “In the end, it was language we thought we could agree to. It’s a balancing act.”
