Acupuncture is an alternative medical method that originated from China.
This method is based upon the old Chinese assumption that there are invisible energy point scattered across the human body. Theses energy points are called Meridians. during an Acupuncture treatment, tiny needles are inserted into the Meridians, causing he energy flow through them to change. This principle is used for quit a few benefits:

* It can "open up" energy blocks that will relieve pain and stress

* It can reduce cravings

* It can strengthen your energy and vitality

In the past years, Acupuncture has been used, among other uses, to help people stop smoking. The treatment included inserting the needles to specific points (among them, a few points in the outer ear).
This treatment was supposed to reduce the cravings to another cigarette and help those people on their way to quit smoking. In the first few years of using this method, it was quit popular and gained a lot of followers that recommended it. That was mainly because the method is not invasive and is very suitable for people who can't, or won't take medicine and other "strong stuff".
But, for the last few years, the use of Acupuncture in smoking cessation has reduced significantly. This happens because of the following reasons:

* The percentage of people who actually stooped smoking while using Acupuncture
was small. This indicated that Acupuncture is not the best choice for people who want to quit smoking.

* New solutions were introduced to the scene, such as laser treatment, and shots treatment. This article does not discuss these methods, so let's just say that they proved to be by far more effective than Acupuncture.

To conclude, It is clear that Acupuncture has it's place as an alternative method, and many people report getting results with it. If you want to give it a shot in your efforts to stop smoking, it is advised that you find a therapist with a proven back record of success with helping people stop smoking.
However, I would say that as a means to help smoking cessation, there are much better solutions out there, so Acupuncture is in my opinion not the best choice.
