In which age group is substance abuse most frequently initiated?

• A. 10-14 years
• B. 15-19 years
• C. 20-24 years
• D. 25-30 years

Answer: (B)

Substance abuse is most frequently initiated in the age group of 15-19 years due to several developmental and sociocultural factors. Adolescents in this age bracket are often exploring their identities and assert their independence, which can lead them to experiment with drugs and alcohol. Peer influence is particularly strong during these teenage years, as social acceptance and belonging become paramount. Additionally, the availability of substances and risk-taking behavior commonly increase during late adolescence, contributing to higher initiation rates during this time.

Studies consistently show that most individuals who develop substance use disorders start using during their teenage years. This age group is critical as it is often when many young people encounter substances for the first time, potentially leading to patterns of use that can persist into adulthood. Understanding this peak age range can help in developing prevention strategies targeting adolescents before they begin experimenting with substances.
