There's no such thing as being drunk in the Spirit. It was a slanderous attack on believers by unbelievers.

(Acts 2:1-18 NIV) When the day of Pentecost came, they were all together in one place. {2} Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. {3} They saw what seemed to be tongues of fire that separated and came to rest on each of them. {4} All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them. {5} Now there were staying in Jerusalem God-fearing Jews from every nation under heaven. {6} When they heard this sound, a crowd came together in bewilderment, because each one heard them speaking in his own language. {7} Utterly amazed, they asked: "Are not all these men who are speaking Galileans? {8} Then how is it that each of us hears them in his own native language? {9} Parthians, Medes and Elamites; residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, {10} Phrygia and Pamphylia, Egypt and the parts of Libya near Cyrene; visitors from Rome {11} (both Jews and converts to Judaism); Cretans and Arabs--we hear them declaring the wonders of God in our own tongues!" {12} Amazed and perplexed, they asked one another, "What does this mean?" {13} Some, however, made fun of them and said, "They have had too much wine." {14} Then Peter stood up with the Eleven, raised his voice and addressed the crowd: "Fellow Jews and all of you who live in Jerusalem, let me explain this to you; listen carefully to what I say. {15} These men are not drunk, as you suppose. It's only nine in the morning! {16} No, this is what was spoken by the prophet Joel: {17} "'In the last days, God says, I will pour out my Spirit on all people. Your sons and daughters will prophesy, your young men will see visions, your old men will dream dreams. {18} Even on my servants, both men and women, I will pour out my Spirit in those days, and they will prophesy.
