The good news? the Journal of Pharmaceutical Sciences is to publish a report on how marijuana smoked from a vaporizer (they cite the Volcano by name, which is really nifty) is a "safe and effective" delivery system. I.e. not dangerous. I.e. a major political argument for medipot, that smoked marijuana does harm and thus is unsafe, is burnt to nothing like a cashed bowl.
The Volcano The better news? The report comes from Leiden University - in the Netherlands! Can't get enough of those wonderful Dutch. Amsterdamn good research, guys! Still, the National Organization for the Remanding of Marijuana Laws has known about this since 2004.
