Patient Query
Hello Doctor,
If my nicotine and cotinine levels are <2, does that suggest high exposure to secondhand smoke?

Hello,
Thank you for reaching out to Dr. Galen. Please find the below response to your query.
Generally, not necessarily, unless there's recent nicotine reintroduction. High levels can persist from prior nicotine dependence, even without recent exposure. Consider nicotine patch substitution or rehabilitation to address addiction.
Thanks
