Nicotine is an addictive stimulant and is one of the main factors leading to continued tobacco smoking. Although the percentage of the nicotine inhaled with tobacco smoke is quite small (most of the substance is destroyed by the heat) it is still sufficient to cause physical and/or psychological dependence. Prior to habituation, teen tobacco smokers often focus on the reinforcing properties of smoking rather than the associated health risks. Because the diseases caused by smoking surface relatively later in life, teenagers do not see their actions as harmful. As a result, they do not serve to deter smoking given the immediate gratification offered by smoking. The depressant effect of smoking calms nerves and sometimes allows for increased concentration by decreasing anxiety. This is another appealing reason and attraction for teens to smoke. Nicotine seems to provide both a stimulant and a depressant effect, and it is likely that the effect it has at any time is determined by the mood of the user, the environment and the circumstances of use. Studies have suggested that low doses have a depressant effect, whilst higher doses have stimulant effect. However, it is impossible to differentiate a drug effect brought on by nicotine use, and the alleviation of nicotine withdrawal.
Somatic and psychological effects of nicotine
The disturbing statistics according to studies by Henningfield and Benowitz, overall nicotine is more addictive than marajuana, caffeine, ethanol, cocaine, and heroin when considering both somatic and psychological dependence. However, due to the stronger withdrawal effects of ethanol, cocaine and heroin, nicotine may have a lower potential for somatic dependence than these substances. A study by Perrine concludes that nicotine's potential for psychological dependency exceeds all other studied drugs - even ethanol, an extremely physically addictive substance with severe withdrawal symptoms that can be fatal. Recent evidence has shown that smoking tobacco increases the release of dopamine in the brain, specifically in the mesolimbic pathway, the same neuro-reward circuit activated by drugs of abuse such as heroin and cocaine. This suggests nicotine use has a pleasurable effect that triggers positive reinforcement which is what many teenagers are lacking in their lives today.By: MarkPetersonArticle Directory: http://www.articledashboard.comMark Peterson has done a lot of research about troubled teens .
