• Likelihood of choosing a brand with higher nicotine content is related to:

• Increasing duration of use• Increasing intensity of use• Frequency of ST use [Tomar, 1995 #2892]

• ST users who have used higher nicotine-containing products are more likely to report:

• More nicotine withdrawal symptoms• Continued use because of difficulty quitting
