Health effects of very light cigarette smoking over the long term

What are the health effects of very light cigarette smoking (1-3 per week) over the long term?
The highly dangerous effects of cigarette smoking are well known, however (from my understanding) this is based on studies that have considered the difference between non-smokers and 1+ pack/day smokers.
So, what are the health effects of very light cigarette smoking? Define very light as being 1-3 cigarettes per week, perhaps less.
Are the effects at that dosage negligible or almost the same? Obviously I would expect it to be somewhere in between, but are there any studies that demonstrate this? One might expect that the effect of smoking is exponential, and there is a tipping point where the impact starts becoming much more pronounced with additional use. Or, one might expect that any exposure is detrimental.
I've googled it using the search terms that I could think of, but found nothing. Can anyone point to any research on this topic?
Anecdotal evidence, although interesting, would probably not be helpful in this circumstance.
