电子尼古丁输送系统 (ENDS) 在南非显示出双重潜力,对一些人来说是戒烟的帮助,但对其他人来说是尼古丁和香烟使用的门户. 干预措施必须尽量减少新的ENDS用户,并支持现有的双重用户戒烟.
科学领域:
- 公共卫生 公共卫生
- 流行病学 流行病学
- 行为科学 行为科学
背景情况:
- 电子尼古丁输送系统 (ENDS) 构成了复杂的公共卫生挑战,可能有助于吸烟者戒烟.
- 相反,ENDS可能成为非吸烟者中尼古丁成和随后的香烟使用的门户.
- 了解这些双重角色对于南非有效的烟草控制政策至关重要.
研究的目的:
- 量化与电子尼古丁输送系统 (ENDS) 和南非卷烟使用相关的开始和停止行为.
- 开发一种类型学,根据 ENDS 和吸烟的顺序对个人进行分类.
- 为政策干预提供信息,旨在优化ENDS用于戒断的使用,同时减轻成风险.
主要方法:
- 对21263名城市南非人的全国代表性电话调查的分析.
- 开发771个双重用户的类型,根据产品启动序列将它们分为"上","下","失败的下"和"持续的双重消费者".
- 调查双重消费者使用ENDS的主要动机,特别是关于戒烟的动机.
主要成果:
- 在总样本中,1.7%的人使用了没有先前吸烟的ENDS,这表明了潜在的"上升".
- 在双重用户中,8.8%是"上",13.9%是"下",20.9%是"失败的下",56.4%是"持续的双重消费者".
- 大约一半的"脱者"",失败的脱者"和"持续的双重消费者"报告使用ENDS戒烟.
结论:
- 在南非,ENDS与吸烟之间的关系是多方面的,有很大比例的吸烟者试图戒烟.
- 政策的重点应该是尽量减少"上升" (在吸烟之前启动ENDS) 和最大限度地减少"下降" (使用ENDS戒烟).
- 针对性戒烟支持对于试图戒烟的使用ENDS的人来说至关重要,因为持续的双重使用和失败的戒烟尝试的高率.

Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
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...
