Abstract:
Little is known about cigarette smoking among opioid users who are not in substance abuse treatment. The study examined cigarette smoking in out-of-treatment opioid users presenting at a hospital who participated in drug abuse research. Participants exhibited a high rate of smoking (92%) at baseline that remained unchanged at one year and were moderately nicotine-dependent. Nineteen percent preferred unfiltered cigarettes. Women were more likely to smoke menthol cigarettes; men were more likely to smoke unfiltered cigarettes. Caucasians tended to smoke more than other ethnicities and exhibited greater dependence. Out-of-treatment drug users continue to be at high risk for continued smoking.

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...
