The reason why smoking is so addictive is due to nicotine, the active ingredient within cigarettes. Cigarette smoke is inhaled and travels into the lungs where it can then enter the bloodstream. While in the bloodstream, the cigarette smoke will travel to different parts of the brain within seconds and elicit a pleasurable feeling.

This is why it is more common for smokers to crave cigarettes during periods of stress. The highly addictive nature of cigarette smoke is comparable to that of cocaine because addicts take the drug in order to release that pleasurable feeling.

Symptoms associated with an addiction to cigarette smoking consists of:

* Lethargy
* Difficulty sleeping and concentrating
* Increased Appetite

There are different treatment options available such as:

* Joining a smoking cessation program
* Individual counseling
* Self-help group therapy
