Among today’s society, many individuals partake in the habit of smoking tobacco for recreational purposes. These individuals may not understand the short term or long term side effects that can occur within their bodies. Although individuals may not think smoking can affect them, it may affect other individuals that surround them. The topic of secondhand smoke is so crucial because secondhand smoke is extremely poisonous to others who may involuntarily inhale the smoke or come in contact with it. Second-hand smoke is more damaging to individuals who do not smoke tobacco for their bodies has not developed certain antigens or immunities that can defend the body from inhaled, harmful carcinogens. According to the National Cancer Institute, second-hand smoke is considered to be more chemically hazardous and more harmful towards the human body because it contains numerous, cancerous carcinogens, such as arsenic, ethylene oxide, and formaldehyde (http://www.cancer.gov/cancertopics/factsheet/Tobacco/ETS). These chemicals, plus many more, are known to cause, or contribute to, cancer within the human body. Cancer, or other health problems, associated with second-hand smoke is no joke. Cancer affects millions of individuals daily, either directly or indirectly. Communities and public venues should advocate for more awareness on the side effects second-hand smoke can have on a human being in order to prevent increased risks fro cancer or other health complications.
