If you've managed not to smoke for a good few weeks or months, then you may think you are safe from falling into the same old trap again
You may even start thinking that 'just one can't hurt', but unfortunately, smoking is incredibly addictive and you could be hooked again before you know it. On a physical level, research suggests that the brains of smokers are permanently altered, making them forever extra sensitive to the effects of smoked nicotine. On a psychological level, many quitters experiment with 1-2 cigarettes and then feel bad about themselves. This weakens their resistance to the addiction and they quickly return to their old smoking levels, even though they are no longer heavily nicotine dependent.
This process has been termed the abstinence violation effect and happens with other addictions too.
