What is the ruling on smoking, selling it, and earning from it?

Question:
Please advise us, may you be rewarded, about the ruling on smoking, and also about one who trades in its sale while he does not smoke it himself; is his earnings lawful or forbidden?

Answer:
Selling tobacco is forbidden, trading in it is forbidden, earning from it is forbidden, and smoking it is forbidden. It is obligatory to be cautious of this, and it is obligatory to advise one another to abandon it, because of the many harms in it, the dire consequences, the squandering of wealth, and the harm to religion and worldly life. So it is obligatory to be cautious of this. It is not permissible for a believer to sell it, trade in it, or smoke it at all.
And so it is with the rest of the harmful substances, narcotics, and intoxicants; they are all forbidden, and their evil is all great. An intoxicant is forbidden of whatever kind it is, and that which harms you in your religion and your worldly life is forbidden, even if it does not intoxicate.
