Actually people have inhaled cinammon in incenses for thousand of years. Try it with cinammon, myrhh, weed, and a little clary sage. Put it in a small bowl over some burning charcoal, and set to inhaling. It'll be worth it, and the smell will be amazing. Weed is also good with sandalwood and juniper, the smells seems to mix nicely. Remember, people have been burning, eating, inhaling, and anally absorbing plants far longer than we can imagine. Try any and everything, you never know what you might happen upon.
