When you smoke a lot of weed your appetite can go down when your not high. This is Bongrexia, Weedrexia, Potrexia osv. The best way get hungry again is to not smoke for a while. or you could smoke more and then get the munchies...
Henrik: Hey man wanna grab a kebab?
Eirik: No man last week has given me a real bad case of Bongrexia.
Henrik: Okey man, i've got a little piece of bubble inside, we could light that up and then go to eat.
Eirik: Sounds like a plan...
