Galatians 5:19-21 (NASB)
Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality, idolatry, sorcery (see note below), enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, envying, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God.
Note: The word translated "sorcery" is the NT Greek word φαρμακεία (pharmakeia) which has multiple meanings:
1) the use or the administering of drugs
2) poisoning
3) sorcery, magical arts, often found in connection with idolatry and fostered by it
So, in the NT times, there was a correlation between drug use and sorcery. This is often a text used to explain the Christian prohibition against drug use, especially those used with pagan rituals.
Also, there are general principles that Christian should consider when approaching drug use.
1) the use or the administering of drugs
Under that broad reading, medicinal drugs would be ruled out - as would the drug alcohol.
2) poisoning
Not the intent of any recreational drug use - and in the sense of chemical toxicity no more applicable to other drugs (and less applicable to marijuana) than to alcohol.
3) sorcery, magical arts, often found in connection with idolatry and fostered by it
Irrelevant to the question of recreational drug use.
Also, there are general principles that Christian should consider when approaching drug use.
"The Bible does not directly address any form of illicit drug use."
Bears repeating.
"Christians are under a universal mandate to respect and obey the laws of the land"
If drugs were legalized this wouldn't apply.
"For example, Christians are all required to be good stewards of what God has entrusted to us, regardless of our national identity (Matthew 25:13-30). This includes our earthly bodies. Unfortunately, illicit drug use is an extremely effective way to destroy your health, not just physically, but mentally and emotionally as well. [...] the apostolic exhortations to remain sober-minded and alert [...] Any time spent kneeling before the god of drugs is time spent with your back towards the God of the Bible."
All equally applicable to alcohol.
