Before western civilisation, there was no term "adolescence", and before the early 19th century, a child fully developed into an adult at the beginning of puberty. Western civilisation is blanketing teenagers too much, protecting them too much from the real world and shielding them from the harsh realities of life. Society is treating teenagers too much like children. In the book "The Case Against Adolescence" by Robert Epstein (2007), Epstein writes of how before western cultures invented the label "adolescence" (and in non-industrial cultures), teenagers were mature and capable adults, and rarely acted disrespectful or irresponsible. In "The Myth of Adolescence Raising responsible children in an irresponsible society", the author mentions that in the bible, Jesus became and was treated like an adult once he had turned 12 years old. Society has made a certain perception of teenagers as irresponsible and disrespectful because of observations of few teenagers. Most teenagers are able-minded, and are ready to make our own decisions and take responsibility for our actions, but cannot break this mould that society has shaped us into. Teenagers can simply not be freed from the domineering ways of western society, and are often treated like children.
Teens have developed the use of drugs and other actions that made them into irresponsible adults. Did the word adolescence, really create irresponsible people? No no it didn't People being irresponsible did.
