The Word of Wisdom and Spirituality (1.2)
Members write in asking if this thing or that is against the Word of Wisdom.
It’s well known that tea, coffee, liquor, and tobacco are against it.  It has not been spelled out in more detail.  Rather, we teach the principle together with the promised blessings.
There are many habit-forming, addictive things that one can drink or chew or inhale or inject which injure both body and spirit which are not mentioned in the revelation.
