Embalming fluid is a known carcinogen. Just having normal contact with it (like touching it or inhaling fumes from being around it) can give you cancer. While I don't know of any studies done on the hazards of smoking it, I would have to guess that it would be extremely dangerous, possibly deadly. THe lungs are a very delicate tissue that can easily be burned and many injuries to the lung tissue are permanent, meaning that the damage will not heal. However, I strongly believe in Darwin's law (survival of the fittest) so maybe if your stupid enough to smoke it, you should go ahead and do so. Have fun with that.
