i've never tried a Volcano but i do own a Vaporbrothers. it pretty much sits in the corner. i really enjoy the high from it. it is more of a deep mellow high. my ears and face get warm.but while smoking all strains tend to take on the toasted vaporized flavor. i was told when i bought it that it would bring out the flavor. Wrong! it all tastes the same. and then the put were there is NO smoke. it is somewhat unsatisfiying to exhale a huge hit and not see smoke. tends to make me smoke more.
health effects are a definate benefit. if there is any breathing related health issues a vaporizers is the only way. it does give a smooth non-carcenigenic vapor. the safest way to smoke.
the invisible high.
