The banning of smoking and including ecigs in that ban is becoming very common in US colleges and universities, and it's not a great thing. These blanket bans are especially misguided in a college setting, as college is often a time for experimentation and free living, as it were. Given that these bans are often based on ignorance about the dangers and effects of ecigarettes, it seems especially wrong for learning institutions to implement such policies.
That said it might be ok to restrict areas where people can vape, so as not to create nuisances.
It does seem that most of these bans on vaping in outdoor areas are all based on ignorance. This is why I think that college students who are members here should take the advice I gave the poster about what they can do:
Go to the school newspaper. Give them the true facts. If you want to get the word out, there's no other better venue.
