>>279678The only purpose of the Official Zippo© Fluid® is to be used when you smoke, as the naphta vapors aren't very toxic, at least not more than your smoke, and they don't leave any bad taste to it.
When you need light a fire innawoods, you don't put fucking naphta in it. And actually, if you're okay with it, you can still light your smoke with it, and the vapors will make you high. Some people like it, I know I do.
