Even though nicotine’s high isn’t as dramatic as cocaine’s or heroin’s, it’s just as addictive as those illegal drugs.
Nicotine affects all areas of your body, from your heart and blood vessels to your hormones, metabolism, and brain.
Nicotine withdrawal is very real. Stop using it, and you’ll physically crave that nicotine hit and become irritable if you can’t have it.
Nicotine withdrawal usually lasts only a month or so, but you could be fighting the mental battle against cigarettes for a long time.
