Second hand smoke harmful to snakes?

[rabernet]

Yes everyone, of course smoking is bad for me, you, and everything alive.
I think that I have not asked this very well since I don't think anyone has really answered as I had hoped. Yes, I realize the medical implications of smoking. The question IS, should someone who smokes not own any pets? As I said, I am helping this guy set up a tank for a snake. Should he have one at all? Is the snake just going to get an RI in a week and die? That is why I am asking for people who smoke who own snakes. Do they all die? Do people who own other pets just have sick dogs and cats or what? I'm not a vet so I don't really know the degree of damage it can do.
If anyone has any experience with this, please comment.

I'm a smoker. My college kitties lived to be 14 (died of cancer caused by his vaccinations called Fibro Sarcoma, none of my cats now are given yearly vaccinations past their first 2 years - a plan that both my vet and I have agreed to based on the cases of Fibro Sarcoma popping up at injection sites now and many pets lost to it). The other two were 15 and 16 and neither developed cancer.

My current dog is 10 years old and is a large breed dog and is still very active. I keep a collection of about 50 snakes, none of which have ever had an RI's in my care.

Edit - I also have retired breeder rats that are over 3 years old (average lifespan is 2 years).

I do smoke in my home, mainly when I'm on the computer.
