Can Christians manufacture cigarettes? My husband and I were discussing an essay my nephew wrote where he says he wants to manufacture cigarettes. I thought it was a good dream but shouldn't we address whether this is something that is good to people who use them? My husband said there is nothing wrong with manufacturing cigarettes because the bible doesn't forbid it. Are there verses that are relevant to my question?
While it is possible that Christians may disagree about this issue, with some claiming verses such as:

Command those who are rich in this present world not to be arrogant nor to put their hope in wealth, which is so uncertain, but to put their hope in God, who richly provides us with everything for our enjoyment. - 1 Timothy 6:17 NIV (emphasis added)

could be interpreted to grant implicit permission towards smoking cigarettes and that therefore their manufacture is morally neutral and an acceptable occupation to engage in; this is a considerably more difficult case to maintain since it has become common knowledge that smoking cigarettes is harmful.
Of considerable relevance to a Christian's consideration of whether an occupation is consistent with Biblical principles are the following:

35 One of them, an expert in the law, tested him with this question: 36 “Teacher, which is the greatest commandment in the Law?”
37 Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ 38 This is the first and greatest commandment. 39 And the second is like it: ‘Love your neighbor as yourself.’ 40 All the Law and the Prophets hang on these two commandments.” - Matthew 22:35-40 NIV
Love does no harm to a neighbor. Therefore love is the fulfillment of the law. - Romans 13:10 NIV (emphasis added)

Many would argue that taken together, the fact that cigarettes are known to be harmful  and the importance of loving our neighbor in a way that does them no harm constitute a strong reason that a Christian should not engage in the manufacture of cigarettes.
