Given the pattern of nicotine absorption described above there can be no doubt that snus is dependence forming in much the same way as other forms of tobacco consumption. There is some evidence that the dependence potential of nicotine and other psychoactive drugs is related to their speed of delivery to the brain and so one would expect snus and other non-inhaled forms of nicotine delivery to be proportionately less addictive than inhaled tobacco smoke. However, there is clear evidence that users of products with snus-like nicotine delivery profiles develop cravings and nicotine withdrawal symptoms when attempting to abstain, and find it difficult to quit. While snus probably does not produce stronger nicotine dependence than smoking, it has just minimal, if any, advantages over cigarettes or other smokeless nicotine delivery products in terms of its lower potential to induce dependence. In fact, its high nicotine delivery and hence dependence potential (relative to most other non-smoked delivery modalities) may be a critical factor enabling it to compete with the more rapidly absorbed nicotine from smoked tobacco.

CPHPS is the recipient of an unrestricted gift from U.S. Smokeless Tobacco Company for support of research of Dr. Carl V. Phillips. This research was investigator-initiated. USSTC did not influence the content or see the study results before they were publicly released. Phillips and Wang have received consulting fees from USSTC related to litigation. Phillips is the recipient of an unrestricted research grant from USSTC at the University of Alberta where he will soon be employed.
