The metabolite ratio was significantly correlated with self-described level of addiction (r=.50, p=.03). That is, the higher the rate of metabolism, the higher the self-described level of addiction was reported. No significant correlations were found between the metabolite ratio and nicotine dependence as measured by the mFTQ or the HONC (r=.22, p=.29 and r=.30, p= .21 respectively). There was no correlation between the nicotine metabolite ratio and the number of cigarettes smoked per day (r=.10, p=.68). The withdrawal score at 24 hours was not correlated with cigarettes per day (r=.28, p=.28).
