Make an argument as to which of these three vices poses the biggest threat to high school teenagers: drinking soda, smoking or marijuana use.
Advocate groups are currently attacking the soda industry, which has very few regulations to follow. Nearly every child has access to it. The cigarette manufacturers have been chastised and regulated for decades concerning their health risks, but selling them to minors is forbidden, and certain areas are now off-limits to smokers. Marijuana is an illegal drug (with minor exceptions) and it is regulated by strong punitive measures for every age group.
Drinking soda is the greatest danger because it is much more prevalent than either of the other two. It is not as big of a threat to each individual who does it, but there are so many more people drinking soda than doing the other two things that the cumulative threat of soda is greater.
America has a serious problem with obesity today. It is a leading cause of health problems and of the rise in health care costs. Drinking soda contributes greatly to obesity. People who are obese are more susceptible to such things as heart disease, high blood pressure, and diabetes. These are conditions that can have extremely serious impacts on their lives.
Soda helps lead to many health problems. Many teens drink soda and there is little social pressure to abstain (in contrast to smoking and marijuana). Therefore, soda drinking is the most dangerous of these vices.
