What about the opposite effect? I know/think I'm addicted to cigarettes, I smoke a couple every day, but the times I've stopped smoking for weeks/months at a time (most recently a year ago), I feel no withdrawal symptoms nor typical signs of dependency. But after smoking for more than 15 years, I'm either addicted or have some sort of addiction resistance... But knowing myself with other substances, I don't think it's the latter. Funny how different bodies seem to react very differently to substances...
