actually the vapor meight go into ur throat an sooth it. maby it keeps ur throat moist so the smoke doesnt dry ur throat raw during a fat rip. if u wanna try something new and odd, use chilled milk, its a little thicker an when ur done, wa-la u can fuck wit a friend sayin its chocolate milk an if hes really stoned he actually meight think it is. but make sore u clean ur bong afterwards cause rotton milk can spoil any good tastin weed.
