What are the pros and cons of smoking marijuana with a vaporizer?

All pros: Vaporizing marijuana releases the medicinally active cannabinoids without burning the plant releasing toxic byproducts of combustion that can be respiratory irritants. Basically there are many pros and no significant cons, though some people don't find it as satisfying at first.
