I'm not sure if this thread will be deleted or not since sometimes this type of thing turns into a debate, but I will just post what I believe.
While there are verses about not being drunk with wine and the one you were referring to about drunkenness, Galatians 5 also mentions this. However, the concern isn't just drunkenness, but also envy, strife, etc. It says those who do these things (the word do there means to habitually do something, not just one act) shall not inherit the kingdom of God. So then it's a matter of the heart. There is a verse (that I can't find right now) that says only God and the man know the thoughts of a man's heart. So my answer to you is yes, it is possible because only God and your friend know what is going on in your friend's heart, and besides He will have mercy on whom He will have mercy and compassion on whom he will have compassion (Romans 9:15).
Hope that helps.
