In the Mesa Community College District, the use of tobacco products has been banned, and a violation of this policy constitutes a breach of the student code of conduct.
At Arizona State University, it is hoped that community enforcement will be enough to deter smokers on campus. However, there is mention of disciplinary action for those who violate university policy.
At the University of Minnesota-Duluth, you can become a “supporter” to enforce their complete ban on tobacco. http://www.d.umn.edu/breathefree/
