I've never smoked cigarettes.
I've enjoyed cigars and pipes for 15+ years, but not more than one a day (and usually less often).
My tolerance for nicotine is somewhat low.
However, since trying snuff a couple months ago, I'm now enjoying this 3-4 times per day. My smoking frequency has declined even further ... and my wish list on Mr. Snuff and Old Mill keeps growing. Perhaps this is just the effect of a new, very enjoyable and even less expensive "hobby", and the novelty will slow down after awhile.
