Pipe Weed - hennethannun @Wiki

The tobacco of Middle-earth. Originally brought to Middle-earth from Numenor, pipe-weed grew abundantly in Gondor but only with great care in the North, in places like Longbottom and Bree. In Gondor pipe-weed was esteemed gor the fragrance of its flowers, but Hobbits, probably in Bree, were the first to smoke it. Dwarves, Rangers, Gandalf, and other wanderers picked up the habit at the Prancing Pony, and about TA 2670 Tobold Hornblower grew pipe-weed for the first time in the Shire. Of the Companions of the Ring, Gandalf, Aragorn, Merry, Pippin, and Gimli were avid smokers, but Legolas, perhaps in common with all Elves, disapproved of the habit.
