Abstract:
This article reviews studies dealing with the content of electronic (e-) cigarettes. Based on measurements of the e-juice, the inhaled and the exhaled vapour, it is sound to assume that smoking e-cigarettes might have much less detrimental health effects than smoking conventional cigarettes. However, propylene glycol and glycerine are abundant in e-cigarettes and although they are generally perceived as relatively harmless, the long-term effects of heavy exposure to these substances are unknown.

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...
