This is what a friend was told by a local dispensary "budsman." He had vaporizers for sale but gave that advice instead. Not having been in the game for long, I've never heard nor read anything like that. My 5 or 6 interactions with different dispensaries and staffs have left me not impressed with their knowledge.
So I'm asking for any links or info that anyone might have on this. Documented research would great, anecdotes and opinions not so much.
Thanks.

How is it different from smoking? Why Vaporize?
Because it is much healthier than combusting!
Although both vaporization and combustion use heat to release the active ingredients, the major differences are the temperature used and the resulting by-products of each method.
When smoking, temperatures can reach ~800-900C. At these temperatures pyrolization occurs. This process not only chemically alters some of the actives (and thus, deactivates them), but results in harmful by-products including carbon monoxide, benzene, toluene, naphthalene, tars, particulates and polyaromatic hydrocarbons.
When vaporized, the herb stays below the point of combustion (approx. 230C). Desired active compounds are released, while harmful combustion by-products are dramatically reduced or avoided entirely.
After combustion, any remaining material is a black, soot-type ash. Since vaporizing doesn't burn the product, the structural integrity of the herb is for the most part maintained (the remaining material generally weighs less than the input material). Vaporized remains, commonly referred to as ABV (Already Been Vaped), are often saved by the user in order to further extract active compounds. Users can revape, cook with and/or make a tincture from the ABV in order to extract remaining actives. The color of the ABV can be a primary indicator of the difference between combusting and vaporizing.
Stripped of many of the byproducts of combustion, users often report a more refined and purer taste to vapors. Further, vapors are generally less irritating than smoke allowing the user inhale deeply and for a long duration. Many vaporists report a "cleaner" high relative to smoking, often void of the "couch-lock" experience and relative lethargy.
Many users report that they use less material when vaporizing as opposed to smoking/combusting. Also, the possibility of reusing/recycling the ABV allows a user to get multiple uses out of the same material."
