Measured 6 months after Quit Day
Secondary outcome [1] 1311 0
1) That the use of NRT in the two weeks prior to quitting followed by standard NRT treatment for eight weeks is more effective than standard NRT treatment alone, on smoking abstinence.

Timepoint [3] 1313 0
Measured at 3 and 6 months after Quit Day.
Secondary outcome [4] 1314 0
