Expert: Michael Dean Date: 5/29/2008 Subject: the effects of very occasional smoking
Question Dear Dr. Dean, I am the father of a young man about to turn 20 years old. I've raised him less with prohibitions than with notions of practicing moderation and making wise choices. He is well-disciplined, and quite self-aware. In general, I feel confident about his choices. I am writing you to ask about one of these choices, having to do with tobacco, which I don't feel I know enough about to judge: he likes to smoke two or three cigarettes a week. He likes the effect of the nicotine on his mental state, and he limits himself to that amount. He knows about the dangers of addiction with nicotine, and he knows the damage to health that cigarettes can do. What neither of us knows is whether two or three cigarettes a week constitute any threat to health worth being concerned about. That's my question to you: if you assume that he will continue to exercise such discipline regarding amount and frequency, would you worry about such use as I describe? He shows no signs of any problems in his respiratory system, but as a youngster he did have episodes of asthma, generally triggered by colds or other upper respiratory infections. Thank you for your counsel.
Answer Dear Andrew,
It is great that you have such good communication with your son. In general, I agree that moderation is best. But with tobacco there is so safe level of use. Regular, even modest use, leads to more severe addiction. In a young person with a history of asthma there is particular danger, and the risk of cancer in later life never goes away.
We have a great excess of lung capacity so we don't show signs of lung disease, until we are quite impaired.
So my counsel would be that he should quit. He might try a nicotine gum, lozenge, or nasal spray, as a substitute. That is perfectly safe.
Let me know how it goes,
Mike
