Stop Smoking Ear Magnets

No. Unless the placebo effect is enough to help you do these things, small magnets placed in the ear or elsewhere will not change anything. Think of it this way. The Earth is a huge magnet, you're surrounded by powerful magnetic fields. Is it a magnet which is about 1/100th as strong no effect at all?

It's a scam that plays on the good things in non-traditional medicine and Eastern medicine, but it is neither of these things, just a scam to tackle those who seek easy solutions to difficult problems.
