What is the laser treatment to stop smoking?

My friend told me her dad just got a laser treatment to stop smoking, and he hasn’t picked up a cigarette since the day he got it. My mom is very adamant about quitting and I think this is a really good option if it works. Shes tried all the gums, pills and patches and nothing has worked. Can anyone help me out and tell me more about it, and how effictive it is?
