Yeah, cigarettes and smoking in general is forbidden in Islam as it is detrimental to the health. In essence you are committing suicide. Muslims are commanded to take care of their health as much as possible. There is even a hadith about how much you should eat along the lines of having 1/3 of the stomach for food, 1/3 for water and 1/3 to remain empty.
