Perceived Nicotine Replacement Therapy Safety
Single item measure of perceived nicotine replacement therapy safety, "Nicotine replacement therapy products (also known as NRT) include the nicotine patch, gum, lozenge, nasal spray, and inhaler. On a scale of 1 to 5, where 1 is not at all and 5 is very, how concerned are you about the safety of NRT products?" For this outcome, we report the change from baseline to the 6 month follow-up.
