Alcohol is allowed, being a drunkard is not. A drunkard meaning someone who is addicted to alcohol, a perpetual user who often or every time they drink, they do so to the point of being drunk.
However, I believe that in no way says one cannot get drunk on rare occasion. I would not be doing that regularly still, but I'm saying that in times of our lives when we have trouble dealing, loss of a loved one, things like that, things of the "broken hear" variety, one gets drunk a few times to forget/get through a tough time, fine, as long as they don't stay in that state.
It is also biblical for those sick and or dying to use alcohol, and if I'm not mistaken, the "Poor at heart" as well, something that backs up what I just said about heart broken people tying one on.
These things are a lot like use of narcotics for temporary pain, use them, for what, as least I think, God designed them for, to not only feel better when we are hurt (the euphoria factor), but to relieve pain, a perfect drug for some situations. The heart can hurt as badly, if not not worse than our physical body, and God has seen to it there are things to help us along for both types of pain, but they should be used with the utmost of discretion.
That said, The bible also says we should not drink at all. Not that it's a sin in moderation, but it's just not a good idea for the Christian. The pint a day in the OP, not a problem, at least as far as sin itself goes. The ciggs? we'll get to that in a moment.
FWIW, I used to drink plenty, but just don't happen to like it anymore, even a little. I smoked for 45 or so yrs. I would love to be allowed by God to smoke still.
The cigarettes? First, if people/Christians want to smoke or do anything for that matter, we'll will find a way to make it OK in our minds. Those are the type that may tend to go for the faith only doctrine, because it allows us to do what we want, not what God wants, a complete delusion of a doctrin.
As far as not smoking not being in the bible, not partaking of one of the many slow killing poisons are also not mentioned in the bible. The bible doesn't say not to drink hemlock . See, there is a point we have to use our God given common sense, and as I mentioned, if someone wants to do something bad enough, they will drop the common sense/do whatever it takes to justify it.
Some say suicide is a real problem with God, a problem to the point of eternal damnation. I'm torn on that, but if you believe that, how can you smoke in good conscience?
Those were just a few comments before I get into the real meat of the issue, in that the bible "does" mention drugs. Instead of repeating myself, here is a link to something I have believed is a fact since the 70's. One can complicate it in their minds but it's really very simple, strait forward, and you can verify it for yourself.. Also remember nicotine is not only a drug, but a very addicted/powerful drug. And honestly, from someone who has used most drugs over the years, ciggs are kind of a rip off, the buzz is not much at all but the cost can be tremendous. Bad deal.
Anyway, here's that link on the bible and drugs, and I should add I didn't post a lot of scripture in the preceding for the sake of time and many know what I say is Biblical already, but if you need that, just let me know.
