For the most part, yes. I know that some guys have a hard time just breathing through their nose, but that is my most natural way to breath, and my throat seems to expand and contract to my breathing through my nose cadence and keep the smoke rolling, but just slightly.
This whole technique depends on eventually just forgetting about the pipe. It helps to do something that gets your mind off of smoking, like reading a book, carving, driving, mowing the lawn, whatever you like to do. I do this mostly as I work at my work bench. I just have to check occasionally to make sure it is still lit, lol.
Also, I notice that after doing this a while, that the back of my throat fills with smoke. So, if someone walks up to me and asks me a question, smoke will roll out of my throat as I talk, making my girlfriend accuse me of inhaling. Now, I make sure I blow it out and take a breath before I talk to her, ha ha.
