Effects on your body

The amount of nicotine entering the lungs, oral cavity, and gastrointestinal system, is increased by smoking (about 90% is absorbed into your body)!

The nicotine particles act on every cell (all your organs are made of little units called cells) in your body. But remember, there are no healthy benefits of taking nicotine.

In your body nicotine can increase salivation (makes you drool), increase stomach acid and motility (gives you heartburn and diarrhea), and increase heart rate and blood pressure.

In your brain nicotine can act as a psychomotor stimulant, increase alertness, increase concentration, increase attention, and can make you less hungry. Maybe this sounds great, but wait there's more!!!

Repeated use produces tolerance and dependence (you're addicted and can't live without the stuff) in as little as a week! 70% of those who quit relapse in one year.

And, there's even a withdrawal syndrome (so now it's even gonna make you sick when you try to quit). So when you're not smoking you might become irritable, have less concentration, gain some weight, and maybe some tremors. But the worst will probably be those intense cravings for another puff to get your nicotine.
The bad news is withdrawal occurs within several hours of your last fix and is about 1 week long (unfortunately, the cravings and weight gain may last a little longer). This is what stops many people from being able to quit.

The good news is, there is help and support to help you kick the nicotine addiction.
