Objectives:
To examine patterns of smokeless tobacco (SLT) use, by type, in wave 1 (2013-2014) of the Population Assessment of Tobacco and Health Study in the United States.
Methods:
We analyzed data from 32 320 adults (aged ≥ 18 years) to assess the use of pouched snus and other SLT products (loose snus, moist snuff, dip, spit, and chewing tobacco).
Results:
Overall, SLT use was most common among men, younger adults, non-Hispanic Whites, and nonurban respondents. Pouched snus users were more likely to report nondaily and polytobacco use than users of other SLT products. Respondents who used SLT some days were more likely to be current established cigarette smokers than those who used SLT every day (57.9% vs 20.2%). Furthermore, current established smokers who used SLT some days were more likely to smoke every day and had a higher median number of cigarettes smoked per day than smokers who used SLT every day.
Conclusions:
Polytobacco use, especially cigarette smoking, is common among SLT users. Pouched snus users are more likely to report nondaily snus use and polytobacco use than users of other SLT products.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
