Comparing the Effects of Electronic Cigarette Vapor and Cigarette Smoke in a Novel In Vivo Exposure System
Published on: May 24, 2017
Abstract:
Heart rate, hand tremor, skin temperature, eating, and craving for cigarettes were examined in 19 smokers who quit for 1 day. Measures of heart rate and hand tremor were lower during abstinence; craving seemed greater, skin temperature was higher, and there was more eating, particularly snacking, but no shift in preference towards sweet foods. Quitting brings about profound changes in a smoker's physiology and behaviour, even during the first day. Anticipation of these changes could help would-be quitters, and those who advise them.

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...
