I have been using nicotine patch and have noticed that I am more focuses and alert, what are the benefits of nicotine and do they out way the con's?

Quit ASAP. A though you feel relaxed, within your body, your heart is actually working harder to pump blood for oxygen intake. Leading 2 strain on the heart which in tome can cause heart attack or stroke. It is also a vasoconstrictor causing the blood vessels to constrict, which also increases risk of heart attack. It can lead 2 lung damage and copd. The advantages are very short lived. Quit asap.
