I usually have a big ole spit pile of Beech Nut or Red Man under my tree & have had for most of 30+ years.  I quit for some time & then "fell off the wagon".

Most the deer I cared didn't react one way or the other, but I've also had them sniff it closely out of curiosity.

I don't think it has any impact on the deer, but when they remove half of your jaw, where do you anchor?

Sorry, but I lost my uncle to mouth and throat cancer. First they took the right half of his lower jaw. A few years later, the cancer was back. When he died he was 5'11" and weighed 67 pounds.

I'll just hunt without tobacco, thank you.

Never had a problem. I don't see anything when I dip, and I don't see anything when I don't dip. The key is that I don't want to kill someone when I have the dip in. 30coupe. Sorry for your loss. I guess we all take our chances.
