I don't think smoking cigarettes is good for you. In this day and age, EVERYONE knows it's bad, cigs are full of toxins. That being said, smoking is considered to be related to spiritism, not the " good kind " like Aaron's magic rocks, but the bad kind, like Yoga and actual meditation.
If you believe the bible is Gods word, then you must avoid defilements of the flesh. Of course, the WTBTS is totally hypocritical. They say they won't go beyond the things written, but they do. So you can't smoke or chew cocaine leaves or have a beard, but you can molest a child some years ago and be re-appointed by the Holy Spirit.. Go figure.
