Smoking has many negative health effects and causes over 480,000 deaths per year in the United States. While smoking is highly addictive due to chemicals like nicotine, there are many resources available to help people quit, such as smoking cessation classes and online advice pages. Laws around the world have also been put in place to discourage smoking and protect nonsmokers from secondhand smoke, though e-cigarettes are a newer option for some trying to quit conventional cigarettes. Continued public health campaigns and the rising costs of cigarettes are also helping to reduce smoking rates over time.
