I am not a neuroscientist, but I thought the actual physiological cause of addiction was similar in both nicotine and gambling: you crave the predictable release of dopamine.
If that is the (heavily simplified) case, is there a distinction for you between a chemically-induced dopamine release from smoking and, say, and a button you can press that magically releases dopamine in your brain?
