Discover why tobacco is so addictive, focusing on nicotine's role and how it affects brain chemistry and withdrawal symptoms.
Video transcript
Tobacco is highly addictive due to its active ingredient, nicotine. Nicotine stimulates the release of neurotransmitters like dopamine, creating feelings of pleasure and reward. Over time, the brain develops a dependency on nicotine to release these chemicals, making it difficult for users to quit. Withdrawal symptoms, such as irritability and cravings, further complicate the cessation process, reinforcing the addiction cycle.
