Final answer:
Tobacco-related disease highlights the addictive nature of nicotine, which can lead to severe withdrawal symptoms and cardiovascular disease, and challenges in quitting despite available cessation aids.
Step-by-step explanation:
Tobacco-related disease provides a compelling illustration of nicotine's addictive power. Nicotine addiction is comparable to that of hardcore substances like heroin and cocaine, and its withdrawal symptoms can be severe, including cravings, headaches, irritability, and difficulty concentrating.
Despite being legal, nicotine use carries significant health risks, including serious cardiovascular disease and various cancers.
Nicotine replacement therapy and other smoking cessation aids are used to help people break free from nicotine dependence, but their long-term effectiveness is debatable.
