Outcome Measure:

Comparison of Urine Cotinine Levels and Total Nicotine Equivalent (TNE)

Outcome Description:

Two urine cotinine levels are taken, one at baseline and one at week 1, to assess cotinine levels for nicotine exposure. TNE is the sum of nicotine, cotinine, trans 3'-hydroxycotinine and their respective glucouronide conjugates.
