The study confirmed that daily smokers are more dependent than Intermittent smokers (ITS) and that converted ITS are more dependent than never daily ITS. Importantly, ITS exhibit features of dependence, and there is meaningful variation in dependence within ITS, suggesting that some aspects of dependence may appear with very infrequent smoking.

While they able abstain from smoking - often for many days at a time - our study demonstrated that non-daily (or "intermittent") smokers do display signs of nicotine dependence. This may hamper intermittent smokers' attempts to quit smoking completely.
