Not much literature on vaping as yet. However, British authorities currently consider vaping to be significantly safer than smoking, and encourage smokers to switch in order to help them quit.
Also, vaping fluids don't contain the many, many compounds which are present in tobacco smoke and known to be dangerous, so it seems quite likely it's significantly safer. The unanswered questions are over what long-term inhalation of vaping fluid might do.
