Skaug acknowledged that some students might feel they should be allowed to consume marijuana on campus if it is legal everywhere else.
"It may be something worth starting a discussion on," Skaug said. "But there are a lot of issues that need to be addressed."
Colleges in Washington already dealt with this issue in 1998 when the state approved the use of medical marijuana, which was also banned on campus, Watkins said.
Students who wanted to use marijuana for medical reasons had to live off-campus, and Washington State waived its requirement that all freshmen had to live in dorms to accommodate them, Watkins said.
Of course, pot has been illegally used on college campuses for decades, and students for decades have been getting busted for possession.
Marum said that many Washington State students who have medical marijuana cards are allowed by their residence hall advisers to consume marijuana brownies, even though the drug is banned on campus.
"People in dorms now who want to smoke, they do it," Marum said. "I do think more people will be smoking in the dorms when marijuana is legal for use."
One thing that will change: Some off-campus police departments have said they will no longer arrest or ticket students who are 21 and older and using marijuana.
In Boulder and Seattle, prosecutors have said they will not prosecute criminal marijuana cases for less than an ounce for people age 21 and over.
Huff said University of Colorado police will no longer ticket people who are legal under state law to possess marijuana.
