Why don't people just live and let live?
If you like a pipe go for it. I personally have always loved the smell of them.
There are lots of things we do that can kill us. From driving fast to large fries....as long as you're not hurting someone enjoy them if you like. There are these things called telemeres and that thing called fate. The graveyard is full of people who lived perfect lives.
Just remember there are some required accessories........
