Smoking Cigarettes is the worst thing you can do to yourself. although legal in united states, people should stop destroying their lives. smoking can cause lung cancer and infect the body with all its contaminents. Marijuana is illegal and benefits people in many ways. I believe cigarettes should be illegal and marijauna should be legal throughout the whole united states. Cigarettes also contaminate the people around its consumer, which is second hand smoking which i think is horrible. People that do not smoke and still get affected is not right. my father smokes and I think its the nastiest thing ever. I have personally tried one and realized how gross it was and how it should not be done.
