AP PSYCHOLOGY

Detailed explanation-1: -Nicotine makes your body release adrenaline, which causes your heart to beat faster and your blood pressure to rise. High blood pressure is bad because it makes your heart work harder. When anxiety causes panic attacks, your body releases adrenaline because it thinks you’re in danger.

Detailed explanation-2: -Immediately after exposure to nicotine, there is a “kick” caused in part by the drug’s stimulation of the adrenal glands and resulting discharge of epinephrine (adrenaline). The rush of adrenaline stimulates the body and causes an increase in blood pressure, respiration, and heart rate.

Detailed explanation-3: -Cigarette smoking increases efferent sympathetic nerve traffic acutely, 4, 5 as well as norepinephrine and epinephrine release. This catecholamine release increases myocardial work and oxygen consumption through an increase in blood pressure (BP), heart rate (HR), and myocardial contractility.

Detailed explanation-4: -Nicotine, a highly addictive chemical found in cigarettes and other tobacco products, has harmful effects on your heart and vascular system. It can cause your blood pressure to increase, heart to race, arteries to narrow and it can increase the flow of blood to your heart, according to the American Heart Association.

Detailed explanation-5: -Nicotine first causes a release of the hormone epinephrine, which further stimulates the nervous system and is responsible for part of the “kick” from nicotine-the drug-induced feelings of pleasure and, over time, addiction. Nicotine also promotes the release of the hormone beta-endorphin, which inhibits pain.
