Smoking ban now in effect at ASU's campuses

A smoking ban has gone into effect at Arizona State University's campuses.
But how it will be enforced and how violators will be punished remains unclear.
The Arizona Republic  says the ban prohibits smoking and the use of smokeless tobacco at all ASU's properties including the main campus in Tempe and all other campuses in the Phoenix metropolitan area.
The policy also applies to privately owned vehicles in the university's parking lots and garages as well as property leased by the school.
Before the ban took effect Thursday, people could smoke outside of buildings at ASU as long as they were 25 feet from entrances.
ASU campus police say officers won't be fining or arresting people who violate the ban, but they'll let smokers know about the new restrictions.
