Well share some tips which helpful for smokers..
My one friend wana to get rid from smoking, how can he do that?
I have an idea for you to help him
give him sugar pills telling him it will make him stop smoking (dont tell him there sugar pills). and second give him to magenets and tell him to put them on his ears when he sleeps.
know these things normaly dont do anything but if you tell him they will work, and his mind and body believes it, the body will quit because it thinks its working
