As a ghost, I think you still go about doing shit you did when you were alive, because ghosts are trapped between life and death so they just act like they are living because they don't realize they are dead. In the "afterlife" though, I dont think we will need to smoke weed because we will be pure and feel awesome all the time.
my house is haunted by a ghost who smokes all the time... fucking annoying cause he always pinches my stash
Seriously? It's like that question, like if you ever found a really awesome looking door that you knew led to some weird alternate universe/ time travel, but you didnt know what the effects would be on your body or if you'd ever be able to come home again, would you go through the door?
That's not an option. It's just you and your body and this door that will disappear really quickly if you don't make a decision! Haha, what am I talking about right now? I need to pass out
