There are many species of tobacco; Nicotiana tabacum (or common tobacco) is used to make cigarettes.
Nicotine, a potent central nervous system stimulant found naturally in the tobacco leaf, is classified as a drug. Nicotine is one of the primary ingredients in tobacco. It’s usually used as an insecticide.
Tobacco leaves may be burned and inhaled (in the form of cigarettes, cigars, pipes, smoke, etc.) or absorbed through the mouth (in the kind of spit tobacco, chew, or snuff).
Smokers usually feel dizzy and sick when they inhale the nicotine in tobacco, but slowly build up tolerance to its effects. Other symptoms fresh smokers experience includes coughing, a dry, irritated throat in addition to nausea, fatigue, abdominal cramps, headache, coughing or gagging.
Nicotine is extremely addictive. The addictive effect of nicotine is the major reason why tobacco is widely used. Many smokers continue to smoke to be able to prevent the pain of withdrawal symptoms. Smokers also adjust their behaviour (inhaling more deeply, by way of instance ) to maintain a certain amount of nicotine in the body.
Smokers who usually smoke at least 15 cigarettes each day or smoke their first Cigarette of the day within 30 minutes of waking are most likely to experience nicotine withdrawal symptoms. They will probably find quitting uncomfortable.
Stopping can create unpleasant withdrawal symptoms such as depression, sleeplessness, irritability, difficulty concentrating, restlessness, anxiety, decreased heart rate, increased appetite, weight gain, and craving for nicotine.
Symptoms summit from 24 to 48 hours after quitting and may last from three days up to four weeks, even though the craving for a Cigarette can last for weeks.
Most smokers make an average of three or four quit attempts before getting long-term non-smokers. Relapse is the rule instead of the exception and must be seen as part of this process of stopping.
