It's effects are complex. Its both a stimulant and a relaxant, depending on the dose, the individual, and the effect being looked at.

This is about my same experience, relaxes my body, but stimulates my mind (not in a caffeine way).I find that a pipe relaxes my body (mostly because I am not doing anything but smoking the pipe in the moment — makes me slow down and be in the moment), but stimulates my mind.
A yes, the morning constitutional.Morning coffee stimulates my bowel movements. Double effect when paired with a pipe!
