Actually thats true…. my old man once told me that 9 out of 10 times you do it its correct. Thats why I choose trojan.

Not too much, especially since you will be using less herb.

If you want to cut down the odor even more, you can exhale into the filters used in respirators (like used by paint spray guys). You only need the canisters refills — call around industrial suppliers, or order one from McMaster.com (see part number 5834T11 on their website for a cheap one for organic vapors !) Just tape the canister to the end of a tube that is about the same size (you can use rolled up cardboard) and exhale into the tube so all your breath will go thru the filter.

Another thing – some vaporizers smell all by themselves with no weed ! Some cheap ones use crappy materials and the heat makes them smell and even give off toxic gasses like formaldehyde. So don’t buy a cheap one — Vaporbrothers is a really good brand and won’t smell or kill you with some gas.
