Galatians 5:19-20 KJV
Now the works of the flesh are manifest, which are these ; Adultery, fornication, uncleanness, lasciviousness,  Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
This word witchcraft in the above verse is the same word in the Greek that we get our word, pharmacy from. This is why I would consider any mind altering drug or beverage to be a form of witchcraft or sorcery[drug related sorcery]. Here is the breakdown from a Greek lexicon:
pharmakeia: the use of medicine, drugs or spells
Original Word: φαρμακεία, ας, ἡ
5331 pharmakeía (from pharmakeuō, “administer drugs”) – properly, drug-related sorcery, like the practice of magical-arts, etc. (A. T. Robertson).

This is why the Bible says to stay away from alcohol for social purposes. It alters your mind. And drugs are an obvious no. These are a form of witchcraft. Outside of the medical reasons this would also explain why drugs and alcohol are so addicting. And this is also why it is a spiritual bondage and only Jesus Christ can break the chains of addiction.
