the filter is made to trap the heavier compounds in smoke.. usually the tar.

THC is similar to nicotine in that it is very light and can pass through filters easily..

I just did it with a chamber full of ice and water, and I must say.. I could still taste it, but I ripped probably a .8 gram (about the amount you would put in a normal sized joint) bowl, completely milked the chamber, cleared it.. and felt absolutly NO harsh feeling in my lungs and throat... but I STILL got mashed off of just one hit (and it usually takes me 1 or two BIG rips to feel high) I was wanting to know if anyone Rating: 5
