Document Summary
Most smokers are young adults ages 18-25 who say they only drink at parties or when they are with their friends who smoke (dangerous because occasional smokers are less likely to quit) Each year, about 1 million people quit smoking, but 43% will relapse. It has been said that it takes the average smoker 3. 2 quit attempts before actually stopping. Smoking rates of aboriginal youth are more than double the smoking rate of other. Nicotine stimulates the release of epinephrine, norepinephrine and dopamine from the brain. At low doses, nicotine can act as a stimulant (increasing alertness, concentration, rapid information processing, memory and learning in adults but in teens who smoke, opposite effects will occur) Studies show that smokers experience milder mood variation than non-smokers while performing long, boring tasks. Relapse rates similar to alcoholics and heroin addicts. Social and psychological forces combine with physiological addiction to maintain the tobacco smoking habit.
