How nicotine works
“In 1988 the U.S. Surgeon General concluded that nicotine in tobacco is addictive. Nicotine addiction is similar to heroin or cocaine addiction”. In 1988 the U.S. Surgeon General concluded that nicotine in tobacco is addictive. The three major findings were:
- Cigarette smoking and other forms of tobacco use are addictive
- Nicotine is the drug in tobacco that causes addiction
- Nicotine addiction is similar to heroin or cocaine addiction.
Nicotine causes chemical or biological changes in the brain. This effect is called psychoactive and although it is less dramatic than heroin or cocaine, the strength of the addiction is just as powerful. It is a ‘reinforcing’ drug, which means that users desire the drug regardless of the damaging effects. For example, in research conducted in 1994, only 50% of smokers who suffered a heart attack managed to quit smoking even though their doctors advised them to. Coincidentally, 50% of all regular smokers die as a result of smoking.
Nicotine addiction is a physical dependency. Withdrawal symptoms are severe and most smokers cannot quit on their first attempt because of these symptoms.
The human body builds a tolerance to nicotine and the effect of the drug is reduced over time. As a result, regular smokers can inhale greater amounts of smoke and therefore greater amounts of toxins, without showing immediate effects (ie coughing, nausea).
Nicotine is extremely poisonous if consumed in large amounts and most people feel sick and dizzy the first time they smoke. These negative affects are quickly overcome. Over time the body builds a tolerance to nicotine, resulting in an increase in the amount of cigarettes smoked.
Nicotine in the body
Cigarette smoke is acidic and therefore nicotine is absorbed through the lungs. Pipe and cigar smoke is alkaline and the nicotine is absorbed through the mouth. Human lungs are very efficient in absorbing nicotine which then moves through the bloodstream and into the brain and other organs of the body.
It takes only 10 seconds for nicotine to reach the brain after being inhaled. This causes several physiological reactions day.
- Acute increase in heart rate and blood pressure
- Constriction of blood vessels causing a temperature drop in the hands and feet
- Brain waves are altered and muscles relax.
Levels of dependency
Levels of dependency vary, but 89% of smokers have a cigarette every one to two hours throughout the day.A highly addicted smoker smokes more than 25 cigarettes a day, ranks the first cigarette in the day as the most important, and will smoke within 30 minutes of waking up.
Without the use of hypnosis the most severe withdrawal symptoms occur within the first few days. The desire to smoke tends to be especially strong when a person is under stress. The typical withdrawal symptoms are:
- anxiety and irritability
- difficulty concentrating and sleeping
- decreased heart rate and blood pressure
- craving for nicotine
Other side-effects, such as tiredness and coughing, are indications that the body is in a state of repair and is cleaning out the poisons associated with smoking. According to the U.S. Lung Health Study, weight gain for men averaged 4.9 kg and 5.2 kg. for women in the first year after quitting.
Most of these unpleasant symptoms can be completely avoided using hypnotherapy.
“Hypnosis is the most effective way of giving up smoking” – New Scientist
There are now more former smokers (26%), over the age of 15, than current smokers (25%).
The most common reason given for quitting smoking is concern about future personal health. Other reasons for quitting were life-style changes, cost of cigarettes, having a baby, and smoke-related illness or death of a friend or family member.
The most common reason current smokers give for not quitting is lack of will-power.
There are five successive stages to quitting smoking:
- Pre-contemplation — not thinking about quitting
- Contemplation — thinking about quitting but not yet ready
- Preparation — getting ready to quit
- Action — quitting
- Maintenance — remaining a non-smoker.
