Absolutely. After all, what do you think they did years ago. As I remember my grandfather and great uncle smoked the same pipe day in and day out. However, if by chance you have a few pipes it's a good idea to give each one a rest for a day or more to let the briar dry out. If by chance you repeatedly smoke the same pipe every day you may find it getting somewhat of a sour taste, but you'll know when that happens and it all comes with some experience. Other than that, don't become overly obsessed with the whole thing.
