Arizona State University now prohibits the use of tobacco products, including cigarettes and chewing tobacco, on any of its properties, indoors and out. The ban took effect Aug. 1.

Sharon Keeler, an ASU spokeswoman, said the university is using a community enforcement method instead of issuing citations for those caught lighting up.

"There is no legal per se because it’s not a crime," Keeler said. "It’s basically a university policy, and so we are hoping community enforcement approach is what works. ... Other universities have proven that it has worked, given that students, staff and faculty members who repeatedly violate the policy could face sanctions.”

ASU will still allow the use of electronic cigarettes outside of buildings, she said.

The University of Arizona still permits outdoor smoking, but that could change. An official from the UA Faculty Senate said work is under way on a draft a policy for a tobacco-free campus. The proposal could be ready for consideration as early as September.
