Explanation:

• For question 5: The teenage brain continues developing until about age 25. This is based on neurodevelopmental research which shows that the prefrontal cortex (involved in decision - making, impulse control etc.) matures later in adolescence.
• For question 6: The hippocampus is responsible for memory and learning. Marijuana use can disrupt the normal functioning of the hippocampus, especially in teens whose brains are still developing.
• For question 7: Regular marijuana use during adolescence can lead to memory problems (due to hippocampal effects) and decreased academic performance (as cognitive functions like attention and learning are affected).
• For question 8: E - cigarette aerosol often contains heavy metals (from heating elements), nicotine (addictive substance), and cancer - causing chemicals (like some flavor - related compounds).
• For question 9: "Popcorn lung" is a type of lung damage. It is caused by inhaling harmful chemicals (such as diacetyl in some vaping products) which damage the small airways in the lungs.
