What Effects Does Nicotine Have on Your Body? Nicotine is the most well-known chemical in tobacco. It is an alkaloid, which means it contains nitrogen and is chemically similar to caffeine and cocaine.
What effects does nicotine have on your body? How is nicotine absorbed by the body?
When you smoke, nicotine enters the bloodstream through the lung membranes. Generally, nicotine is more effectively absorbed in a basic environment. This is why tobacco companies adjust the ingredients of cigarettes to increase the pH level (making it more alkaline) and encourage smokers to consume more nicotine.
Once nicotine reaches the bloodstream, it travels to your heart. From there, it moves to your arteries and brain. This entire process takes 10 to 20 seconds, which is one reason why you get so much nicotine from smoking. The amount of nicotine you get from smoking depends on your brand and how you smoke.
What effects does nicotine have on your body? What are the short-term effects of nicotine on your body?
The short-term effects of nicotine are the main issues you will notice when you vape or smoke. However, it is a bit more complex than you might think.
Nicotine is a stimulant, so it creates a pleasurable feeling while also increasing your heart rate, enhancing your attention, and boosting your memory. However, it has a "biphasic" effect: a little bit acts like a stimulant, but more can relax you.
What effects does nicotine have on your body? How does nicotine work?
The effects of nicotine result from its ability to bind to certain receptors in the brain. Imagine this like a key in a lock: the key has a unique shape that must match the inside of the lock to open it. The "lock" for nicotine is called the nicotinic acetylcholine receptor (nAChRs).
When nicotine binds to the receptors in your brain, it stimulates the release of "neurotransmitters." These are the chemical messengers that the brain uses to send signals, the most famous of which is dopamine.
Dopamine is a neurotransmitter that is often misunderstood, but essentially it helps you remember rewards. This is why it plays a central role in the development of most addictions. However, it also plays a role in remembering negative experiences, and its function is generally much more complex than the typical "reward chemical" explanation.
What effects does nicotine have on your body? Is nicotine harmful?
Now that we know what nicotine is and what happens when you consume it, we can address the most critical question. One assumption behind many arguments against vaping is that nicotine is harmful and should be avoided.
If you are not very familiar with how cigarettes cause harm, this seems entirely reasonable. The simplified view of the issue is that nicotine is in tobacco, tobacco is harmful to you, so nicotine must be harmful to you.
What effects does nicotine have on your body? How toxic is nicotine?
Although we have reported elsewhere, it is worth emphasizing that there is a deep-rooted myth that about 60 milligrams of nicotine is enough to kill an adult. This would exceed several milliliters of 18 mg/ml e-liquid.
This is completely incorrect, and this figure is based on some questionable experiments from the 19th century. In those experiments, researchers reported seizures and other severe symptoms after claiming to have ingested the equivalent of several cigarettes' worth of nicotine (about 4 milligrams). If this were true, we might notice that smokers who frequently smoke in beer gardens often collapse.
In short, if you look at more reliable evidence, the lethal dose is actually 500 to 1000 milligrams, or possibly even more. This far exceeds the reasonable amounts you could encounter through vaping or smoking. If you consider that one of the primary symptoms of nicotine overdose is vomiting and nausea, then you could potentially have problems due to nicotine being "toxic."
