I believe the use of cannabis in this particular ritual is referred to as the ancient practice of suffumigation. This practice goes fairly far back in the literature. > Suffumigation, by definition, means "to fumigate from below." This practice involves herbal incenses burned for magical purposes and is used in Ceremonial Magic to attract certain spirits. When an object is consecrated, it is held in the smoke of the incense, thus suffumigating it. (The Witch Book: The Encyclopedia of Witchcraft, Wicca, and Neo-paganism)
