I love them. I wasn't really looking to quit smoking, I just got into them when my favorite brand of cigaratte became illegal to sell in the States and it was getting expensive to import them, but they've replaced cigarettes for me because they're so much more convenient and the juice is tasty. Still smoke a cigar or pipe or two a day though. There isn't much research on the health risks yet, so there is a chance that there are some. It's seems implausible that there are any more than in smoking cigarettes, though. Buy your juice from vendors in AEMSA if you're concerned. If you go elsewhere (I am willing to live dangerously for Vape Dudes), avoid meat or cream flavored juices [because they are gross and] because they're often the juices that end up containing something known to be dangerous. I second all of insomniasexx's advice.
