The name for a person who decides to smoke incense (a.k.a. pulperie) rather than marijuana. Instead of "pothead", or "dopehead" it is "popehead". Idiots that smoke harmful incense, which is much worse for you than marijuana.
"Dude you are such a popehead"
"Those guys are such popeheads"
"He smokes that fake incense, he's a popehead"
