Cigarette Smoking

Cigarette smoking involves inhaling smoke from burned tobacco, which delivers nicotine—a highly addictive substance—to the brain. This activates pleasure centers, creating a feeling of relaxation or satisfaction. However, smoking introduces thousands of harmful chemicals into the lungs, increasing the risk of respiratory diseases, heart conditions, and various cancers. Despite its addictive nature, many smokers find it challenging to quit due to dependence on nicotine. While smoking can temporarily relieve stress, its long-term health risks far outweigh any short-term benefits. Quitting smoking significantly improves health outlooks and reduces disease risk.
