The other part of the addiction has to do with behaviour. It doesn't take long before tobacco use gets linked with both pleasant and stressful activities and feeling. Together, the nicotine addiction and physical and psychological triggers make tobacco use a hard addiction to break. In fact, cigarettes and other forms of tobacco can be as addictive as heroin and cocaine. Tobacco products aren't only addictive.
Tobacco use causes serious health problems and early death.
The heart pumps blood through blood vessels to all parts of the body. This is how the body gets the oxygen and food energy it needs. But when a person smokes, the carbon monoxide and nicotine in tobacco smoke make blood vessels narrow and blood pressure rise. The means the heart has to beat faster and work harder to do its job. Smoking greatly increases the chance of getting heart disease.
