vaping is generally considered less harmful than smoking traditional cigarettes, it is not completely safe. Studies from the

Public Health England suggest that

If your girlfriend is concerned about health, it might help to focus on balanced information rather than debating. Harm reduction is important, but quitting both habits would be the healthiest choice.
