Makes sense, in Being Human it was shown possession takes its toll on the possessing creature and controlling a human body is not easy. For ghosts its quite draining but also addictive, while a more powerful being like a demon damages the host upon entering and just after; snapping the victim's spine and bones leading to deformed jerking movements. It heals but the demon can rot the host from the inside out if they go with out feeding/ killing for to long.
