People have been smoking for at least 7000 years, but until the 1800s, cigarettes became the smoke of choice after machines were developed to mass-produce them. Two hundred years later in 2003, the บุหรี่ไฟฟ้า was invented in China.
Since then, the use of e-cigarettes has, also called vaping, has grown exponentially around the world.
The core of electronic cigarettes
บุหรี่ไฟฟ้า are electronic devices that vaporize a flavored liquid. They all used to look like cigarettes, but now they come in many shapes and sizes. Many look like pens or small boxes called mods. What they all have in common is a power source which is usually a lithium battery, an atomizer that heats the e-liquid, e-liquid, or e-juice, which contains flavors and nicotine, and a cartridge or tank which is filled with e-liquid.
Heating the e-liquid creates a cloud of vapor that looks like smoke but without many of the lethal components of tobacco smoke. Many people assume e-cigarettes are safer than traditional cigarettes because they do not burn anything or create tar in your lungs.
Although, it took almost 7000 years to realize that tobacco causes lung cancer, throat and mouth cancer, heart attacks, strokes, and lung damage. Meanwhile, electronic cigarettes have only been around a little over a decade, so there just has not been enough time to figure out what effects they will have on your body. We know that it delivers nicotine just like traditional cigarettes causing increased blood rate and heart pressure.
Do e-cigarettes affect the brain?
บุหรี่ไฟฟ้า does contain nicotine which has powerful effects on the brain. It releases rewarding neurotransmitters in the brain like dopamine and changes brain chemistry. It is a stimulant that makes people feel more alert, but they crave it even more, when it goes away. It can interfere with the body’s own natural ability to make dopamine, and soon the user needs nicotine to feel normal.
The developing brain of teenagers is the most vulnerable to these effects. The powerful addictive nature of nicotine is so high that it is comparable to heroin and cocaine. Besides nicotine, e-cigarettes contain chemical solvents. When heated very high by some of the new e-cigarettes devices, these solvents can be transformed into formaldehyde, a carcinogen that causes cancer.
