Vaping is safer than cigarettes, it’s still bad and we don’t know how bad it is long term but it is safer than smoking. It’s better to just stop completely using a stop smoking service to get alternative nicotine products if that’s available. If the person doesn’t want to stop then you’re unlikely to be able to make them however a vape might be able to replace it with something better. Other products to look at are patches, gum, lozenges and inhalators which can be useful in quitting.

In summary smoking and vaping are both bad but smoking is worse. Better off just quitting if possible, if not go for the vape.
