Question 1

How long does it take nicotine to reach the brain following inhalation of cigarette smoke?&#10;A) 10 seconds&#10;B) 60 seconds&#10;C) 5 minutes&#10;D) 15 minutes

Accepted Answer

A cigarette is a very efficient delivery system for the inhalation of nicotine.Nicotine is rapidly distributed throughout the body after inhalation,reaching the brain in as little as 10 seconds.A person who smokes about 30 cigarettes a day gets 300 hits of nicotine to the brain every day,each one within 10 seconds after a puff.

Question 2

How long does it take nicotine blood levels to return to baseline after smoking a cigarette?&#10;A) 1 minute&#10;B) 25 to 30 minutes&#10;C) 3 to 5 hours&#10;D) 1 day

Accepted Answer

Smoking one cigarette rapidly increases nicotine blood levels to 35 to 40 ng/mL,producing the "hit" or "rush" experienced with smoking; this level then gradually returns to baseline within about 25 to 30 minutes.To prevent withdrawal symptoms,a smoker must maintain a baseline level of nicotine of about 15 to 18 ng/mL.
