I did a Google search for “The origins of smoking” and found Wikipedia of course. They say that the origins of smoking started from people burning intense and stuff. I personally believe it started much further back than that. I actually think smoking was used as a method to move fire from one place to another from nearly the beginning. If they smoked in rolled leaves as we do now there would be no evidence of this so it’s hard to prove. If they smoked with some sort of pipe then it might lend some credibility to this theory. However, considering that moving fire was needed and people still till this day will move fire in similar manners in primitive tribes I think it is a valid theory.
