What is the Mormon Attitude on Liquor and Tobacco?

"A code of health and conduct given in 1833 is known as the "Word of Wisdom" disapproves of the use of tobacco, alcoholic beverages and "hot drinks" (specifically tea and coffee). The spirit of the "Word of Wisdom" requires abstinence from all injurious substances and suggests that man should enjoy all the wholesome things of the earth "with prudence and thanksgiving" (Doctrine and Covenants, 89).
