While that might be true there is still a point to be considered regarding vaping which is that it is an order of magnitute less harmful than smoking tabacco cigarettes because nothing is burned in a vape and the "burning stuff" is what makes normal smoking so harmful. Therefore I'd argue it should definitely be available for smokers at a price tag lower than cigarettes if they can't quit smoking to reduce harm. This would massively decrease the huge costs for health care.
