I say yes, but each is entitled to his/her own opinion.
For example, from Romans 14 (vs 19-21 specifically):
19 Let us therefore follow after the things which make for peace, and things wherewith one may edify another.
20 For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence.
21 It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.
I take this to mean that if another will be offended by our partaking (whether that be alcohol or whatever), then we shouldn't do it. Many people take 1 Corinthians (vs 19-20) more literally than others:
19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.
This means that our bodies are sacred. There are different interpretations of this, but I think nearly everyone can agree on that. If are bodies are sacred (and compared to God's holy temple), then we should take care of it. This means that we should put good things in and don't put bad things in.
I take this to mean that anything that has a negative affect on my body (alcohol, tobacco, excessive caffeine/sugar) should be avoided. As such, I don't drink any alcohol and I don't smoke. I also don't drink soda very much in favor of juice (which I think tastes better anyway).
But this can be taken to extremes. Sure, a little sugar is fine, and to some alcohol may be fine. My family happens to have a history of alcoholics (and other addictions), so that's even more reason for me personally to avoid these things.
But always remember Romans 14 (vs 17):
17 For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost.
