Once nicotine gets into your blood it heads right to your brain.
The feel-good chemical in tobacco products is nicotine. Whether you chew tobacco, vape, or smoke cigarettes or cigars, that’s what gives you the buzz. Once nicotine gets into your blood it heads right to your brain. Within 10 seconds it boosts levels of a feel-good chemical in your brain called dopamine. But the rush goes away quickly, so you need more to get the same high. Over time, using nicotine rewires pathways in your brain tied to the way you handle stress. You need it to feel good physically and mentally. In short, you’re addicted.
