Some people dedicate, some don’t, there’s no right or wrong, it’s all about you.
Now when it comes to a blend that might Ghost a pipe, and let’s say your poor as an example, only own a few pipes, so when you dry them, and have one to smoke, you can’t afford to dedicate, based on this sort of idea, of pipe rotation.
So, don’t smoke a lot of the same blend in a pipe that will Ghost it. If you get any Ghosting, you can clean the pipe, people have their various methods, but typically smoking a non Ghosting blends, like Burley or Latakia, you can eventually smoke it out.
I can’t afford to dedicate and anything that might Ghost my pipes, I might only smoke once or twice, then I smoke some other blends until it’s smoked out, which doesn’t take but typically a few bowls.
