This topic has been brought up many times and those who claim bongs filter out thc and thus get you less high often refer to the NORML study which proved this.

ok...first of all, as someone already said, "wasting" is relative. what i think is wasting is not wasting to you or vice versa, plus tolerances are different, plus because of peoples different bodies its entirely possible that different methods get different people stoned.

though studies have been proven to show any number of things, i KNOW based on personal experienced based facts that packing a fat bong bowl and doming it to yourself will get me much more stoned than almost any other method. therefore i find this "bong wastes weed" discussion a waste of time and ultimatly, an argumentative loop.
