I know that magnets are used for stress relief by way of providing pressure on specific acupressure points in the ear. I haven't used them for this purpose, but it makes sense that two magnets on each side of your ear would apply a small amount of pressure (due to their attraction) and we know for sure that certain areas in the body have specific acupressure points.

Because the smoking cessation magnets are placed on the same area of the ear, I would assume that the smoking cessation benefits come from the stress relief that occurs when pressure is applied to that area. Therefore, if you are someone who smokes primarily due to stress, then smoking cessation magnets might prove beneficial.

I think that it is very likely just like any other remedy - you just have to find what works for you. Some folks swear by smoking cessation through meditation, while others require a prescription medication and so forth.

As far as I can tell, both sets of magnets (ones for stress relief as well as ones for smoking cessation) look the same and it looks like they are placed in the same spot as well. This would lead me to believe that you could buy the stress relief magnets (which seem to be cheaper) for either purpose.
