Can your brain recover from nicotine?

What problems can nicotine cause?
Nicotine is a dangerous and highly addictive chemical. It can cause an increase in blood pressure, heart rate, flow of blood to the heart and a narrowing of the arteries (vessels that carry blood). Nicotine may also contribute to the hardening of the arterial walls, which in turn, may lead to a heart attack.
Is nicotine a depressant?
Nicotine acts as both a stimulant and a depressant to the central nervous system.

Does nicotine worsen OCD?

Is nicotine good for your brain?
