Revised Paragraph

Today studies have proven that marijuana use among teenagers has steadily increased throughout the past couple of decades. Studies showed that “Between 1991 and 2001, the percentage of eighth graders who used marijuana doubled from one in ten to one in five” (“Marijuana Use Among Teens”). What phenomenon has caused this increasing trend in statistics? There are many possible aspects of modern culture that could have contributed to the rising numbers. Perhaps it is because the availability of the drug has increased among today’s youth. Peer pressure also has a big effect on teens’ decisions. Marijuana today may also contain stronger, more powerful drugs that make it more addictive. In addition, several key celebrities have seemed to encourage drug use through the highly public examples of their own lifestyles. But more strongly evidenced is the theory that parents’ influence on their children has led to the increase in teenage marijuana use.
