If you breathe in through your nose with the back of the throat slightly closed, smoke will automatically enter the mouth.Thank you very much! You are absolutely right I am litteraly drawing on the pipe, to be completely honest I don't really understand the breathing technique as my pipe is always going out when I try that technique. I think you got a very good pointer there.
I find I get plenty of smoke even without closing my lips around the pipe once the baccy gets burning properly. I just sit there slack-jawed and breathe.
