A:
Using tobacco, whether in the form of cigarettes or powder chewed in the mouth, is Haram (prohibited); because it causes serious harms according to the reports of specialized doctors. (Part No. 22; Page No. 200) Since it is Haram to smoke or chew tobacco, it is also Haram to grow it or trade in it to earn money; because this involves cooperation in sin and transgression. Allah has forbidden this by saying:
...but do not help one another in sin and transgression.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
