The reasons behind not inhaling are rather philosophical in a sense. The concept of pipesmoking is to relax and enjoy the wonderful flavors that the tobacco provides. Inhaling the smoke gives you a much different flavor and experience than if you just puff and slowly blow it out of the mouth and nose. A good parable is that of someone who is a connoisseur of fine wines and someone who guzzles cheap beer to get drunk. A cigarette is simply a vessel for nicotine whereas a pipe or a fine cigar is to be savored slowly to promote a relaxed state and a celebration of the complex flavors that only they can provide. With a pipe you can sit back...relax...reflect and enjoy a blissful escape from the daily stresses of life.
With these thoughts in mind, fill up your favorite briar…strike a match and light up…enjoy.
