The net result is an increase in the amount of tar per hit (and a decrease in the amount of THC/cannabinoids per hit). And in my experience tar doesn't taste very good... I like the taste of pipe smoke much more then water bong smoke.

So, again, with water filtration you have to inhale more tar (plus burn significantly more weed) to get the same amount of THC. Unless you plan on drinking the water, I'd say just forget it.

I personally like using long glass pipes. The longer the pipe, the cooler the smoke gets before it hits your throat and lungs (and the less harsh the smoke). A nice long bong without water is an excellent pipe if you ask me.

Here is the original study by NORML and MAPS on the results of water filtration.
MAPS/CaNORML vaporizer and waterpipe studies
That is absolute bollox. That study sucks. Water pipes do not filter out more thc then carcinogens. That is a ludicrous claim which you should back up with more then that study if it were true. You don't inhale more tar, you inhale less then a normal pipe ffs, adding water is not throwing your weed away!!!!!
