Objectives:
To examine the relationship between nicotine dependence and attitudes, predicted behaviours and support regarding restrictions on smoking.
Design:
Population-based, computer-assisted, telephone survey of adults in Ontario, Canada using a two-stage stratified sampling design; 1764 interviews were completed (65% response rate) yielding 424 (24%) cigarette smokers, of whom 354 (83%) smoked daily. The Heaviness of Smoking Index was used as a measure of nicotine dependence.
Main Outcome Measure:
Attitudes toward smoking restrictions, predicted compliance with more restrictions, and support for total smoking bans.
Results:
Attitudes favorable to smoking restrictions tended to decrease with increased nicotine dependence, but the associations were not statistically significant after adjusting for demographic variables. Predicted compliance with more restrictions on smoking decreased with higher levels of dependence, as did support for a total ban on smoking in restaurants, workplaces, bingo halls, and hockey arenas. Support for smoking bans in food courts, family fast food restaurants, and bars and taverns did not vary significantly with level of nicotine dependence.
Conclusions:
Level of nicotine dependence is associated with intended behaviors and support for smoking restrictions in some settings. These results have implications for tobacco control programs and policies.

Drug Dependence
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 sympathetic or...
