The Bible says to avoid "φαρμακεία" (literally, "poison", translated as "drugs", "witchcraft", etc.): "But if ye be led of the Spirit, ye are not under the law. 19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, 20 Idolatry, [φαρμακεία], hatred, variance, emulations, wrath, strife, seditions, heresies," (From Galatians 5, KJV) "Neither repented they of their murders, nor of their [φαρμακεία], nor of their fornication, nor of their thefts." (Revelation 9:21) "And the light of a candle shall shine no more at all in thee; and the voice of the bridegroom and of the bride shall be heard no more at all in thee: for thy merchants were the great men of the earth; for by thy [φαρμακεία] were all nations deceived ." (Revelation 18:23) By the way, "φαρμακεία" is different than "גהה" or "תרופה" ("medicine"), which in Greek are "θεραπεία" (therpaia) and "φάρμακο"
If Amanda Bynes' case did not prove this, I do not know what did. By the way, if I'm correct, "תרופה" is responsible for the word "θεραπεία". Also, look at the Scriptures, concordances, and Google Translate yourself if you don't believe me. Furthermore, please (like I did) take at least one Hebrew class.
