Nine Toed Hippie brings up a good discussion on why people use a water bong or vaporizer to remove the vegetation flavor of cannabis. Palatable preference as individuals posses more acute senses or become sensitized to undesirable components. I can relay when vaporizing fresh cannabis which is uncured a decreased potency is usualy present leading to my belief either by reduction of undesirable elements allows cannabis composition to improve in a more desirable composition in extended aging and curing process.
