u hiting on a bong or on Joints? If its ur bong it may be ur water i find Alcohol to be a great way to get rid of Harsh hits*chilled Rum with some kind of flavor is nice*. If its Joints its prolly ur paper try some different papers. BLunts are harsh but u can try taken slower hits i find if i hit realy hard real fast it tends 2 burn. It is always nice to keep a cold drink handy.
