What are the Health Risks of Smoking Tobacco?

No matter how you smoke it, tobacco is hazardous to your health. There are no harmless substances in any tobacco products, from acetone and tar to nicotine and carbon monoxide. The contents you inhale don’t just harm your lungs; they can affect your entire body. Smoking causes damage to almost every organ in the body and is directly responsible for several diseases.

Nicotine is the addictive drug in tobacco smoke that causes smokers to keep on smoking. Addicted smokers need plenty of nicotine throughout a day to feel normal to fulfill cravings or control their mood.

Some of these compounds are chemically active and cause acute and harmful changes in the body.

Moreover, withdrawal can also cause headaches and sleep problems.
