Since you asked, it says you aren't in denial about the possibility.
You see us all singing the praises of these devices. However, for most of us, that's because they are saving us from the alternative of smoking. Take a look at some of the posts in here. If you really look around, you'll see these are finicky, trouble prone and at times messy devices. They are a real pain in the .... to use actually. We do it because of our addiction and the alternative is to resign ourselves to an early and pretty horrible death. You don't have that hanging over you.
You've already expressed an affinity for nicotine. If you start using these with nic juice, you are likely to develop a dependency but, let's say you use no nic. One night you're out drinking and you find it's leaked or you're out of juice or the battery goes dead. So, you buy a pack of smokes. You feel that nicotine buzz and realize you've been missing it. That's a great way to start a habit you'll regret ever starting.
Also safer than smoking is a long way from safe and even safer than smoking isn't certain. All of the ingredients in these devices are generally regarded as safe except for the nicotine and at these levels, it's a lot safer than cigarettes. However, there really isn't any hard data on what the effects of inhaling them long term will be. For a smoker, the risks make sense, I'm not sure they do for a non-smoker.
