I'm not sure if a smoking addiction releases dopamine, but nice guide anyway.
To quit smoking in my opinion it's best to get a few friends to try it too. You should stay together for a few days, at each others houses or whatever. It takes 3 days for the nicotine to leave you system, so the first 3 days are the hardest. I tried to quite smoking, it's hard.
Also, reading your guide made me want a ciggy, so I rolled up and smoked. Yay.
