Which of the following is NOT a long-term effect of tobacco use?

Decreased blood pressure is not a long-term effect of tobacco use. In fact, tobacco consumption is typically associated with an increase in blood pressure rather than a decrease. The acute effects of smoking can lead to immediate increases in heart rate and blood pressure due to the stimulating effects of nicotine. Long-term use of tobacco is linked to various cardiovascular issues, such as hypertension, rather than lowering blood pressure.

On the other hand, decreased lung capacity, chronic bronchitis, and increased risk of cancer are all well-documented long-term consequences of tobacco use. Smoking causes significant damage to the lungs over time, leading to decreased lung capacity due to chronic obstructive pulmonary disease (COPD) and conditions like chronic bronchitis. Additionally, tobacco products contain carcinogens that elevate the risk of various cancers, including lung cancer.
