I too think that it's odd that someone who has never smoked would be looking into vaping and not to judge but I think it sounds funny to hear someone say I am looking into vaping to have something to do in between my college classes, it sound like your trying to "fit in" with someone or a group or something. From my experience when people vape for the enjoyment of it, they don't do it with ecig alikes like blu. People use ecigs like blu to quit smoking not to give them something to do. As far as the healthy or not part of it, your still inhaling something into your lungs that while not as bad as cigarette smoke is still not something that is as pure as air. The long term effects are not really known, but for a smoker the risk of the unknown long term effects out weigh the known risks of cigarettes. While you may not develop an addiction to nicotine, you could still develop an addiction to vaping.
If you must then at least do it right, get a model like Halo's G6 where you can buy blank cartridges and fill them with flavored 0 nic juice, hundreds of flavors from hundreds of suppliers, not just the few flavors blu offers. However blu does sell the 0 nic online, you might have a harder time finding them in a convenient place like the gas station or Walgreen, however I haven't looked at what they are selling recently.
