^aMean and standard deviation (SD) presented, odds ratios (OR) for single year raised to the power of 10 to present per 10‐year increase.

^bStrengths of urges to smoke, possible range 0 ‘no urges’ to 5 ‘extremely strong urges’, mean and SD presented, OR per unit increase. HE = higher education; NRT = nicotine replacement therapy.
