Answer 2

Smoking tobacco is linked to multiple metabolic changes that appear in body, some are direct whereas some are indirect. For example, when you smoke, adrenal glands release catecholamines into the bloodstream due to which heart rate and blood pressure increases.

At a cellular level, it has been seen that smoking also causes the release of catecholamine-synthesizing enzyme, speedup the release of other neurotransmitters and hormones in body as well.
