Okay, things are getting cloudy in this room. Let’s clear the air a little.
St. Eric, no I was not serious.
For others, if you are serious, you can go to an online concordance and search for the terms you’re interested in finding in the Bible. There is no verse about smoking harmful or addictive substances.
The ethics about smoking and health are easy enough to see and weigh, and I think responsible adults should make up their own minds.
The question of your reputation is, likewise, up to you. But sometimes we cannot control what others think about our choices, and we then have to decide whether to subjugate those choices in order to increase our influence for good. That’s New Testament ethics (1 Corinthians 8), even though it goes against my grain as much as it does yours.
