From what I have read, it has made people sick (nauseous) to leaving horrible taste in their mouths. To go back to the creosote, that stuff (at least in the state I live in) was outlawed. They used it to treat power polls/telephone polls at the bottle where it was buried and close to the ground to keep from rotting. Creosote as a liquid would eat up your skin with the quickness. I'm sure there were other additives added to the creosote but it's still something I don't want to be injecting into my body.
I would like to hear some others opinions that may be more verse on this.
