“Social smoking can still be detrimental to my health.”
“E-cigarettes can help me wean off nicotine so I can quit.”
“Pack years are calculated by my packs per day multiplied by the number of years I’ve smoked.”
“Nicotine replacement therapy along with a smoking cessation program is the most successful treatment.”
Number 2 is correct.
Rationale: E-cigarettes may contain nicotine and other toxins and are not approved for smoking cessation. Although social smoking is intermittent, it can still have an adverse effect on overall health. Option 3 states the correct method to calculate pack years. Nicotine replacement therapy has a success rate of 50 percent to 70 percent and is highest when used in conjunction with a smoking cessation program.
