By the end of high school, approximately what percent of adolescents experiment with marijuana?

• A. 45
• B. 49
• C. 60
• D. 70

Answer: (B)

Many teens try marijuana during adolescence, and by the time they finish high school, a substantial portion have experimented at least once. This makes “roughly half” the best way to summarize the typical pattern across large groups. It reflects what national surveys consistently find about lifetime experimentation in adolescence: a large minority, around half, will have given it a try by the end of high school. Why this is the best fit: it captures the common, observable trajectory of substance experimentation during adolescence without overstating how widespread ongoing use is. The other options imply much lower or much higher levels than what large-scale data usually show for lifetime experimentation by the end of high school, so they don’t align with the prevailing pattern.
