Help plz! can smoking a vaporizer hinder weight loss?

Don't understand ?: There is nothing about using a vaporizer that would effect weight gain or loss one way or another. If you are smoking a nicotine-containing ecig, nicotine does suppress appetite and would promote weight loss. But this is at the cost of nicotine addiction, and when we are talking ecigs, unknown effects of the propylene glycol, other oils, flavorings, colorings, preservatives in the vapor.
