Physical Effects of Nicotine
Nicotine is a substance found naturally in plants especially the tobacco plant, it is the part of cigarettes and other tobacco products that is responsible for addictions developing. It acts as a stimulant for most smokers and is commonly thought of as one of the most difficult addictions to overcome.
Effects on the Internal Aspects of the Body
Once nicotine is inhaled, it enters the bloodstream and is carried to the brain. Once here, it acts on certain receptors and stimulates hormones and adrenalin release. The increased adrenalin leads to an increase in heart rate, changes in breathing and a rise in blood pressure. The rise in adrenalin causes a surge in glucose production that can take effect as a rush of energy; this may be due to the inhibiting effects nicotine has on insulin release and also may explain why smokers believe their cigarettes help to reduce their appetite.The smoker experiences a fast acting sense of feeling good after the nicotine has reached the brain; it is this that contributes to the addictive quality of nicotine. These feelings of pleasure are caused by an increase in the production and release of a substance called Dopamine. Dopamine levels in the brain are not metabolised as quickly in smokers as non-smokers and the feelings of enjoyment remain for longer.
As the body becomes simultaneously relaxed and stimulated by the effects of nicotine on the brain, the body becomes more dependent and the user often feels the need to take stronger or more frequent doses.It has also been found that nicotine can act as a depressant by altering the communication between cells of the nervous system.
