It probably depends on the smoker.  I only had 3-4 cigs per day unless I was drinking, and just one American Spirit was enough to make me feel not-so-good for half an hour or so after smoking.  A pack-a-day smoker might benefit, except that the habit is just as strong as the addiction so I suspect they&#x27;ll just ingest more nicotine while smoking the same number of cigarettes.<p>I remember reading that the nicotine levels were markedly higher, like an order of magnitude, but I&#x27;m not having any luck finding the numbers (or even the references) to substantiate it.
