as the title reads, allow us to inspect a hookah to see the contents (ie Pipeweed ql69, 0.2kg)
there is no reason why i cant see if i've got either kush, opium, or tobacco. when you're doing credos such as mystic/cave hermit and you have to waste god knows how much perfectly good bud emptying the thing because you have no idea what you last smoked, it's a real pain in the ass, and i can't reasonably keep a hookah for each one and not let them fall in to hell of disorganization.
