He means to get rid of any carbon dust, you should wash your carbon in tap water before use, or risk having dust all up in your tube. Some carbon isn't as dusty as others, but i always wash mine just to be sure.
Carbon is absolutely worth it, despite the small amount of drag it adds because it keeps my glass so damn clean. Its especially useful because it keeps my ac clean as well, and if any of you have any type of tree-perc ac you know it gets dirty as shit FAST. The smoke is much smoother/cleaner, much less harsh with huge hits, and probably better for you since more of the tars/carcinogens are filtered out.
In my experience, the high also changes. It seems to be more cerebral, and doesn't seem to have a ceiling (i.e., the more i smoke the higher i get, seemingly without limit), whereas when the carbon is off, i get less of a head-directed buzz, and once i cross a certain threshold, i cant as easily get more stoned. It also seems to negate some part of my tolerance, and i need less material to get a similar effect. The only thought that i have on this phenomenon is that potentially some of the cbd/cbn is filtered out by carbon, and the smoke is a primarily THC laden hit, which is much different than the combined cbd/cbn/thc of unfiltered herb. I am not a scientist, and have not extensively tested the chemical content of my roor rips, so this is pure conjecture but it seems to make some sort of sense.
Anybody else have similar experiences?
