Q

If a patient asked you if vaping was safe as a means to quit cigarettes, how would you respond in a patient centred manner?

A

Although there are benefits from vaping (less harmful additives + no combustion) they still contain nicotine - so may not help your goal to quit smoking. There is also a long way to go in terms of regulation, clear labelling of ingredients, and regulation of other ingredients that might be harmful. There is still a lot of research that needs to be done and to gauge long term health effects.
