Questions

1. Which part of the brain is most responsible for decision-making and impulse control?

   1. Cerebellum
   2. Brain stem
   3. Prefrontal cortex
   4. Hippocampus
   Show answer

   Answer: Prefrontal cortex

   The prefrontal cortex governs judgment, planning, and impulse control; it continues developing into the mid-20s, making teens more impulsive and risk-prone.

2. What does 'dependence' mean in the context of substance use?

   1. Choosing to use a substance daily
   2. The body requiring a substance to function normally
   3. Enjoying the effects of a substance
   4. Using a substance with friends
   Show answer

   Answer: The body requiring a substance to function normally

   Dependence means the body has physically adapted to require the substance; stopping causes withdrawal symptoms because the body can no longer function normally without it.

3. Which of the following is a PROTECTIVE factor against substance abuse?

   1. Having friends who use substances
   2. High levels of stress
   3. Strong family and community connections
   4. Early exposure to alcohol
   Show answer

   Answer: Strong family and community connections

   Strong social connections and a supportive environment are among the strongest protective factors against substance abuse according to research.

4. A person can become addicted to a substance after just one use in all cases.

   Show answer

   Answer: False

   Addiction typically develops over repeated use as the brain adapts; a single use rarely causes addiction, though some highly addictive substances carry higher risk even early on.

5. What are 'withdrawal symptoms'?

   1. Positive feelings when first using a substance
   2. Physical and psychological symptoms when stopping a substance you are dependent on
   3. Side effects of taking too much of a substance at once
   4. The process of building tolerance
   Show answer

   Answer: Physical and psychological symptoms when stopping a substance you are dependent on

   Withdrawal symptoms occur when a dependent person stops using a substance; symptoms vary by substance and can include anxiety, nausea, sweating, and in severe cases seizures.

6. Why are teenagers considered more at risk for addiction than adults?

   1. They have weaker immune systems
   2. Their brains' reward systems produce less dopamine
   3. Their prefrontal cortex is still developing
   4. They are exposed to fewer social situations
   Show answer

   Answer: Their prefrontal cortex is still developing

   The still-developing prefrontal cortex means teens have less impulse control and are more sensitive to dopamine rewards, making the brain more susceptible to addiction patterns.

7. When the brain gets used to a substance and needs more to feel the same effect, this is called _____.

   Show answer

   Answer: tolerance

   Tolerance is the brain's adaptation to a substance that reduces its effect, driving users to take increasing amounts — a key step in the development of dependence.

8. Which of the following is an effective prevention strategy for substance abuse?

   1. Avoiding all social activities
   2. Learning and practicing refusal skills
   3. Only talking about drugs in negative terms
   4. Never discussing substances with trusted adults
   Show answer

   Answer: Learning and practicing refusal skills

   Refusal skills — learning how to confidently say no in social situations — are one of the most evidence-based and practical prevention strategies for teens.
