While marijuana use is about to become legal in Washington and Colorado, that won't mean pot will be welcome at the states' colleges and universities.
Instead, federal laws and college rules of conduct will combine to keep pot illegal on campuses.
Darin Watkins, a spokesman for Washington State University, says most colleges have student codes of conduct that prohibit marijuana and other drugs - and the ballot measures that legalized pot have no power over those codes.
Watkins says students at Washington State who violate the code face a variety of punishments, up to expulsion.
Also, marijuana remains illegal under federal law, another key reason that campuses will remain cannabis-free.
The Drug Free Schools and Communities Act requires that any university receiving federal funds adopt a program to prevent use of illicit drugs by students and employees.
