Teenage smoking has been a problem for over a century. Smoking itself has existed for thousands of years, but it really took off when cigarettes were invented in the 1840’s. For a long time, smoking was the norm – everybody did it. In fact, in the early 20th century, doctors even encouraged it. Because of this, teen smoking was a major problem for a long time. However, although it was encouraged in the first half of the 20th century, people woke up in the latter half. They realized that smoking caused lung cancer, and from the 1960’s through the 1980’s, smoking became much less popular. In fact, a report published by the CDC in 1992 said that half of smokers quit in that timeframe.
