Abstract:
Studies examining associations between cognitive measures and clinical aspects of smoking are scarce and generally limited to predicting risk profiles or relapses. However, it is essential to understand the influence of several measures of executive function in nicotine addiction in order to investigate factors associated with smoking maintenance. This study examined the ability of working memory and delay discount to predict years of smoking. The sample consisted of 180 smokers who were assessed at baseline with measures of cognitive impulsivity (Delay Discounting Task) and working memory [Visual Search and Attention Test (VSAT) and Letter-Number Sequencing (WAIS III)] while the outcome measure was years of smoking. Consistent with predictions, working memory evaluated with Visual Search and Attention Test was a statistically significant factor in predicting years of nicotine addiction. These findings suggest that working memory is clinically relevant in nicotine dependence and proposes a pattern of executive functioning associated with 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...
