Once again, you know nothing on this topic so please get lost. Yes, a smoking habit is more difficult to kick than a heroin habit. Ask any peraon who has tried atopping and any therapist you wish. Its damn hard.
I really dont want to go off on a tangent here as theyre both extremely difficult habits to stop. However, heroin has much more acute physical withdrawal symptoms.
The reason people say that cigarette smoking is harder to kick is due to the fact that you are (used to be) able to smoke anywhere. And they sell cigarettes everywhere. If a heroin addict stops using heroin and moves to a nice area where he doesnt associate with anyone using heroin he wont have to think about it every time he steps out on the street. However, someone who quits smoking will still have to smell it every time he walks down the street and see it in every gas station and convenience store he walks into. Its also harder to mentally justify since most people havent lost their job or their spouse or their kids because they smoked cigarettes.
But just saying that a smoking habit is harder to kick than heroin is just plain incorrect.
