Background:
This study was done to estimate the smoking cessation rates 4 years after treatment with acupuncture and nicotine gum.
Methods:
Participants were randomized in a 2 x 2 factorial design to four groups: double active treatments (nicotine gum and acupuncture), double placebo, and the combination of one active treatment and placebo.
Results:
The success rates were quite similar in the four groups at the different points of follow-up. They sharply decreased between 1 month (around 23%) and 1 year (around 10%). The decrease slowed down thereafter to around 6% at 4 years.
Conclusions:
Results from our study suggest that the two treatments did not offer any long-term improvement over placebo. Additional investigations are necessary to estimate the magnitude of their long-term success rate.
