Many people are probably familiar with the vaporgenie
I've had mine for about a year now and I've just been using a bic lighter almost exclusively with mine for most of that time. It is thought that the rare earth metals used for flint in lighters are toxic:

That said...is using a bic with a vg especially "unsafe"? I've been using a plain old bic for a while and I let it burn for a few seconds until the flame stops sparking and whatnot. But...if you hold the flame like a foot under your nose you can still smell it giving off some sort of odor as it burns...
Also if I hit the vg, empty, with a bic, it has a definite taste that is not present if I just suck on it without any heat applied (it tastes like metal and I am pretty sure it is not resin of past smokes that I taste).
Additionally, if I smell the inside of the top part where I apply the flame when inhaling, it seems to have sort of a butane-y smell that can kind of be removed by wiping it out with some paper towels...but then the paper towels will smell as well.
I'm going to invest in a torch lighter one of these days, but I cannot help but wonder if the bic flame isn't actually burning as clean as one might like to think?
