So are you for vaping or against it? Ok I read that article and the author is an idiot, the Pax is not a fucking vape pen its a full on portable vaporizer. First of all vaping concentrates is the best way, is he in the stone age using a light bulb? As far as pens go for loose leaf herb there is not one pen on the market yet that does not combust the herb because they all use the heated coil and have no temperature settings. Now if you are using a pen with a concentrate mod you get a true vape of the oil/wax/amber/shatter. The only pen I know of that truly vapes loose leaf herb is the grasshopper and you have to get on a waiting list to get one and it has temp settings and no heated coils.
