Clay pipes with a clay stem if clamped in the teeth you get enough to bits of clay off to trigger a dirt taste with your smoke. It’s not like eating dirt but it the taste off raw veggies.
Reed stems taste like a meerschaum, no noticeable flavor. But as it gets just a little cake you get a woodsy flavor. I smoke an English blend and find it very tasty in clay.
Willow Bark, sweet grass, cedar bark and a bit of cedar ( juniper) leaf, prairie sage, and clover leaf dried and chopped fine, makes a nice kinninkinic for them what’s can’t take tobacco... but be like Bill and don’t inhale. Just a mouthfull of smoke rolled around and blown out.
I'm smoking right now as I write this and and can breath normally with a mouth full of smoke.
