The harm of cigarettes and the nicotine of electronic cigarettes
Nicotine, commonly known as nicotine, is an alkaloid found in Solanaceae (Solanum) and an important component of tobacco. Nicotine can be addictive or dependent (one of the most difficult drug addictions), and repeated use of nicotine also increases heart speed and raises blood pressure and reduces appetite. Nicotine is also an important component of E-liquid.
When nicotine enters the body, it is transmitted through the bloodstream and passes through the blood-brain barrier. After inhalation, it takes only 7 seconds to reach the brain. The half-life of nicotine in the human body is about 2 hours. The amount of nicotine that the body receives through smoking is affected by many factors, including the quality of the smoke, whether it is inhaled, and whether or not the filter is used. Chewing, buccal and inhaled tobaccos are more efficient in entering the body through the inclusion of lip and gums and inhalation directly through the nose. The liver is the organ that primarily metabolizes nicotine.
Nicotine increases the amount of neurotransmitters and increases the amount of dopamine in the brain, producing a sense of well-being and relaxation, and may eventually become addictive due to smoking.
Vape is one of the better nicotine replacement products. E-liquid is used as a carrier to provide enough nicotine for smokers. After using for a period of time, smokers choose low-concentration E-liquid to reduce nicotine. Intake, and then overcome the habit of smoking, to achieve the purpose of successful smoking cessation.
The smoking cessation or smoke replacement effect of vapes has also been supported by the US government. Since the popularity of vapes in the United States, we can see that the smoking rate of young people in the United States is declining year by year, so the effect of smoking cessation or replacement of cigarettes is still very good. Obviously, the current concern or the issue of controversy lies in the safety of vapes, whether it is 95% less harmful than cigarettes.
In fact, the only uniformity of vapes and cigarettes is that E-liquid generally contains nicotine, so I am not discussing the harm of the same nicotine. At least some authoritative parts have come out to prove that nicotine and cancer are irrelevant.
Many people on the Internet have written that vapes are more harmful than cigarettes, but the evidence they can produce is vague. The E-liquid component that can't be said is nothing more than VG and PG, but they avoid talking about it. It is the composition of cigarettes.
For those who are still in the hazard of constant electronic cigarettes and the effects of smoking and smoking cessation of electronic cigarettes, first look at the harmful components of cigarettes and compare the components of electronic cigarettes before making a decision.
Harmful components in cigarette smoke include alkaloids such as carbon monoxide and nicotine, amines, nitriles, alcohols, phenols, alkanes, alkenes, carbonyl compounds, nitrogen oxides, polycyclic aromatic hydrocarbons, heterocyclic compounds, and heavy metal elements.
They have a variety of biological effects, including:
1. Inflammatory stimuli on the respiratory mucosa: such as aldehydes, nitrogen oxides, and olefins.
2, toxic effects on cells: such as nitriles, amines, heavy metal elements.
3, to make people addictive effects: such as nicotine and other alkaloids.
4, carcinogenic effects on the human body: such as polycyclic aromatic hydrocarbons of benzopyrene and cadmium, dimethyl nitrosamine, β-naphthylamine and so on.
5, has a cancer-promoting effect on the human body: such as phenolic compounds.
6, the red blood cells lost oxygen capacity: such as carbon monoxide.
A variety of carcinogens that make up tar, when the amount of inhalation reaches a certain level is a carcinogenic initiator, cancer-promoting agents and synergistic carcinogens can accelerate carcinogenic effects.
