The randomised, double-blind, crossover study compared repetitive transcranial magnetic stimulation (rTMS) and sham TMS of the dorsolateral prefrontal cortex in 16 smokers in two visits separated by a week.

The effect of rTMS on cue craving was positively correlated with nicotine dependence scores and the number of cigarettes
