Randomized trial of brief individual treatment for smoking using nicotine chewing gum in a workplace setting

In a controlled trial of brief treatment for smoking using nicotine chewing gum in a workplace setting, 270 of 334 cigarette smokers who expressed interest were invited to take part in the program, which consisted of two individual consultations; 172 attended. The remaining 64 smokers constituted a no-intervention control group. Using a criterion of sustained one-year abstinence with biochemical validation, success rates were 12 per cent among participants, 1 per cent among those who were invited but did not attend, and 2 per cent in the control group.
