Teenagers often begin using drugs during their teenage years due to natural curiosity and a desire to rebel or feel a sense of belonging with peers. Common reasons for teenage drug abuse include conflicts at home, desires to reduce emotional pain, low self-esteem, and idleness or boredom. Parents should watch for signs of drug abuse like sudden lifestyle changes, mood changes, and failing grades, and seek professional help for their teen if abuse is suspected. Early detection and treatment programs involving therapy and family support can help reduce teenage drug abuse.
