Cigarette manufacturers not only increased the amount of nicotine but also found the way to instantly deliver it into the brain. By adding chemicals such as ammonia and urea, they assure a proper alkaline pH, allowing all nicotine to be converted into the free-based form.
MR. WYDEN. Let me begin my questioning on whether or not nicotine is addictive. Let me ask you first, and I’d like to just go down the row, whether each of you believes that nicotine is not addictive. I heard virtually all of you touch on it. Yes or no, do you believe nicotine is not addictive?
MR. CAMPBELL (President of Philip Morris U.S.A.). I believe nicotine is not addictive, yes.
Breathing even a little secondhand smoke can be harmful. The Surgeon General has concluded that the only way to fully protect yourself and your loved ones from the dangers of secondhand smoke is through 100% smoke-free environments.
A study on British smokers (Doll 2004) shows that the earlier someone stops smoking, the more years of life is preserved. It is important to note that ceasing smoking at 40 years old is estimated to extend life by 9 years. 9 years that could be used to travel the world after retiring or see how a grandchild grows up. This increase in lifespan is information that can be used as motivation to quit, and should be shared with people intending to give up smoking.
Here are some statistics about smoking and also some facts about cigarettes
It is an deep rooted problem in many parts of the world, especially in developing countries where the majority of cigarettes are smoked and in places where public bans have nor or cannot be enforced, like in China. One survey estimated that 79 percent of Europeans over age 15 were exposed to second-hand smoke. Recent data from South Africa shows that 64 percent of children below age five in Soweto live with at least one smoker in the house.
Just taking a look at the different studies, the important factors that will help cease smoking are: support from any friends, increased motivation, being married or having a supportive partner, avoiding smoking environments, minimalize cravings and withdrawal symptoms (using NRT) and having more than 8 counseling sessions lasting 90 minutes each; focusing on aversive smoking techniques, increasing social support and learning rapid smoking techniques
The problem with smoking is that smokers do not only put themselves at risk but also the people around them. The smoke that is exhaled from a smoker or trails off from the tip of the cigarette is called environmental smoke, and breathing in these fumes is known as passive smoking or second hand smoking
Symptoms of nicotine withdrawal are common among people trying to stop the smoking addiction. These symptoms usually peak in the first 3 days and slowly subside over a period of 3-4 weeks.
Nicotine binds selectively to acetylcholine receptors at the autonomic ganglia, in the adrenal medulla, at neuromuscular junctions, and in the brain. Two types of central nervous system (CNS) effects are believed to be the basis of nicotine’s positively reinforcing properties. A stimulating effect, exerted mainly in the cortex via the locus ceruleus, produces increased alertness and cognitive performance. A ‘reward’ effect via the ‘pleasure system’ in the brain is exerted in the limbic system.
