Smoking will be banned in all on-campus dormitories next semester, according to Director of Housing Marc Robillard, after parts of three large dormitories were made smoke-free as a test this year.

Students in apartment-style residences will only be able to smoke if their roommates and neighbors agree to allow smoking, but smoking in “hallways, stairwells, elevators, public bathrooms, lounges and in common areas on sleeping floors” will be prohibited next year, according to the housing website.

The new policy simply expands the ban set last year that prohibited smoking in all common areas and student rooms in Sleeper and Rich halls on West Campus, Fairfield and Marshall towers in Warren Towers and the east tower of the Towers residence. The current standards were a test, Robillard said, and reaction was reviewed at the end of last semester.

“The [new] policy that appears on the Office of Housing website is the result of that review,” Robillard said.

The change was influenced by a concern in quality of life for BU residences and continued requests for a smoke-free campus from both students and parents, Robillard said.

“Only 2 percent of on-campus students report that they smoke,” he said.

Additionally, the recent changes to the city of Boston’s smoking policy contributed to the university’s changes, as city officials implemented Boston’s smoke-free workplace ordinance, which prohibits smoking in all workplaces including restaurants and bars, in May.

Similarly, Northeastern University prohibits smoking in all public areas of residence halls, but allows it in private rooms of some residences, according to the school’s “Guide to Residence Hall Living.”

“Smoking is becoming less socially acceptable,” Robillard said.

But College of Communication freshman Chris Hardiman said the policy change is unfair.

“I don’t see why roommates in dormitory-style residences should not be allowed to smoke in their private rooms if they choose,” Hardiman said. “I might not get into apartment-style housing next year, and if my roommate and I both smoke, we should be allowed to no matter where we live. I don’t see any difference between roommates agreeing in apartment-style housing versus dormitory-style housing.”

The policy has already affected some BU students during the test this year, but it will probably not affect many more next year, College of Arts and Sciences freshman Erik Johnson said.

“I live in a non-smoking tower of Warren Towers, so I just go outside now when I smoke,” he said. “I’ll be living in the same room next year, so it won’t be any different from what I’m doing now.”

CAS freshman Alyssa Bigley, a non-smoker, said people who want to smoke should be allowed to and should not be forced to move elsewhere to do so.

“I feel that no matter how many non-smoking places there are, people are still going to smoke,” Bigley said. “Even though I don’t smoke, I think that if people make that decision, they should be allowed to smoke in their own rooms if their roommates agree.”

Bigley said she is not looking forward to one of the possible effects of the policy change.

“Even now when I leave places like Warren Towers, I step outside and so many people are smoking,” she said. “I don’t like walking into a huge cloud of second-hand smoke. I can only assume that if less people will be allowed to smoke in their dorms next year, more people will be smoking outside more frequently.”

COM sophomore Amanda Candan said she hopes to escape smokers by moving off campus.

“The second-hand smoke outside almost all campus buildings does get irritating,” she said. “I’ll be living off campus next year, so hopefully I won’t have to deal with it as much.”
