Heres another topic that keeps showing up in other threads.

I'm not the worlds most experienced fire-breather -and you're about to find out why- but I have consulted with many of the best and most experienced in many places, and have personally witnessed a lot of things happen, including some amazing stuff, and also including blow-back (as in, a face engulfed in flame) and organ failure.

Even if you: have perfect tecnique learned from the perfect instructor, never make a mistake, never get a drop down your throat, never do it outside in wind conditions that are - lets face it - never 100% predictable (and blow-back is not the worst thing that can happen when the wind shifts), and never do it inside where - lets face it - its very rare that you can be 100% sure that nothing can be hit by your blast...

You are still taking a mouthful of god-knows what petro-chemicals (see fuel theory thread), and your mouth contains porous membranes that transfer those unidentified chemicals directly into your blood-stream.

If you do this on a regular basis, theres a good chance you'll do cumulative damage to the organs that filter toxins. It can result in permananent impairment. What *that* can look like is an expensive hospital stay that wraps up with a finger-waggling doctor saying things like "it will never again be safe for you to imbibe alcohol or other recreational drugs" - on pain of coma or even death.

So:
1) this is the branch of fire-ism whose safety parameters are the most difficult to reliably predict, and
2) accumulative organ damage is highly possible even with flawless tecnique.
This combination is why I refer to fire-breathing as the most dangerous branch of fire performance.

I never blow fire in a regular show with anything that wasn't *expressly designed to be imbibed by humans*. For me its strictly a special occasion thing, a few times a year at most.

And, due to the impairing properties of alcohol, blowing with it had better be your last fire-act of the night!

In theory, its possible that somebody may come up with some concoction that is safe to imbibe and gives you big showy flame like lamp oil - please let us know if you do! - but I suspect those two properties are mutually exclusive. As weak as they are, even 151 Rum and everclear are not the nicest things you can do to your liver.

In short, I wouldn't hold my breath.

Then again, maybe you should.
