Use your head. Smoking is responsible for close to 420,000 deaths each year. Exercising and participating in sports is nearly impossible if you smoke cigarettes. Young smokers are 100 times more likely to smoke pot and become addicted to other illicit substances such as heroin and cocaine. Be aware of the risks.
Smoking can lead to many physical problems, including emphysema, heart disease, stroke, and cancer.
Keep your edge. Smoking makes you smell bad, gives you bad breath, makes your fingers turn yellow, and gives your premature wrinkles. Play it safe. Experimenting with smoking could lead to full-fledged addiction and a lifetime of trying to quit. Do the smart thing.
