In general people get addicted to bad habits easily than to the good ones. This is human psychology. Smoking is a serious issue in terms of addiction. People don’t take smoking addiction as serious as drug addiction because they don’t feel that it will create some serious impacts on health like other drugs does. In fact smoking is more serious than drug addiction. The main reason for this is that people don’t treat it as a serious problem at all. The main factor for smoking addiction is the nicotine in it. Nicotine is a highly addictive psychoactive chemical. Most smokers have a special fondness for the first cigarette of the day because of the way brain cells respond to the day’s first nicotine rush. Nicotine, particularly taken in the first few cigarettes of the day, increases the activity of dopamine, a chemical in the brain that elicits pleasurable sensations, a feeling similar to achieving a reward. The nicotine has a potential for psychological dependency. This dependency is more intense than other drugs like cannabis, caffeine, cocaine, heroin, or ethanol. 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. Knowing about the addiction is probably the best way to stay away from getting addicted.
