Yes, nicotine, especially through tobacco smoking, can hurt your liver by contributing to inflammation, oxidative stress, and fat accumulation, increasing the risk for Non-Alcoholic Fatty Liver Disease (NAFLD), fibrosis, cirrhosis, and liver cancer, though nicotine alone (like in cessation products) isn't strongly linked to acute liver injury. While the liver metabolizes nicotine, its harmful effects stem more from the complex mixture of chemicals in tobacco smoke that strain liver function over time.

What are four signs of nicotine poisoning?

Yes, nicotine is significantly worse for your health than caffeine, as nicotine is highly addictive and directly harms multiple organs (heart, lungs, brain), while caffeine is a milder stimulant with fewer serious risks, though both increase heart rate and can cause jitrums or restlessness, with nicotine's addiction and long-term damage far outweighing caffeine's mild dependence. The biggest danger comes from tobacco products, but nicotine itself causes cardiovascular and developmental harm, even without tar.

Nicotine's effects are complex and depend on dosage, duration, and individual factors, but medical professionals don't recommend it due to its addictive nature and harmful effects on nerve healing.
