Tobacco use increases heart rate and blood pressure.

Explanation:
Nicotine in tobacco products activates the sympathetic nervous system, releasing adrenaline and noradrenaline. This makes the heart beat faster and the blood vessels tighten, which raises both heart rate and blood pressure. The effect happens quickly after tobacco use, so the statement that tobacco use increases heart rate and blood pressure is the accurate one. Decreased heart rate or no change in blood pressure don’t fit the body’s immediate response to nicotine, which is stimulatory and vasoconstrictive. Over time, this repeated stimulation contributes to higher resting blood pressure and greater cardiovascular strain.
