Not in the same realm, but I have a few acquaintances who smoke other naturally occurring plants besides tobacco. I was impressed at some of the ingenuity involved.
One fashioned a makeshift pipe from a high brass shotgun shell base with the primer popped out, and a brass tube cleaning rod as the stem. He had to wear gloves when using it.
Another time, he drilled a pine 2x2" block with a 5/8 drill bit, side drilled a 1/4 inch stem hole. He then lined the bowl with aluminum foil, and used a old style waxed paper soda straw for the stem.
