i did, for 35 years, and it didn't kill me. stopped because it cost toooo dam nuch.
I smoked for about 17 years then stopped - because didn't really think I wanted to smoke. If I start smoking again, I'm not going to get all upset about it.
I was about to quit for the same reason, but found out how cheap it was to roll your own. Better and fresher tobacco, too. And no additives, etc. Buy it by the pound. Less than a buck a pack -- and that's with filter tubes.
Smoking hasn't killed me yet, and I started puffin' years before Lucky Strike Green went to war. It might have effected my brain some, as some of my replies here would clearly show.
What would probably kill me would be if Free Republic were to crash for a week.
