　　Question time:

　　1. What might be the factors that result in smarter kids trying drugs?

　　2. Why drug users with less education and wealth are more likely to be exposed to negative consequences of drug use?

　　【参考答案】

　　1. People with high IQs are more likely to score high on personality scales of openness to experience. They may be more willing to experiment and seek out novel experiences. Another factor could be that the messages used to attempt to deter teens from drug use werent exactly known for the subtlety of their reasoning, so they may not have targeted the smarter group well.

　　2. This is due in part to the fact that money itself can buy protection against the types of criminal involvement and disease that can affect poor drug users.
