The spine is the main walkway on campus and I believe that the spine and arias outside of lecture theatres should be smoke free zones although it is a persons own choice wether they smoke or not the people around them can still experience negative side effects from secondary smoking the reason I feel the spine should be smoke free is there is now way for a non smoker to actively avoid secondary smoking if someone is smoking in front of them , further to this I believe the same should stand for the sugar que and the que for the sugar bus for the same reasons .
