Is it true that nicotine from smokeless tobacco can activate the sympathetic nervous system, increasing heart rate, blood pressure, cardiac stroke volume, cardiac output, and coronary blood flow?

Yes. Nicotine from smokeless tobacco activates the sympathetic nervous system, leading to acute cardiovascular responses such as elevated heart rate and blood pressure, and is consistently linked to increased cardiovascular disease risks.
