   Answers

   1 True. Drug addiction is a "developmental" disease. Recent studies show that the teen brain, parts of which are still developing, is at a greater risk of addiction than a mature brain. The prefrontal cortex is the main part of the brain that people use to make decisions that require judgment and consideration of long-term consequences. Because the prefrontal cortex is still maturing in teens, a brain system that matures earlier--the limbic system--influences a teen's decisions more than it would influence an adult's decisions.

   2 True. Inhalants cause toxic chemical vapors to race through the body. A single session of repeatedly inhaling highly concentrated amounts of inhalant chemicals can cause asphyxiation or cardiac arrest, even in a healthy young person. Sudden sniffing death is the name given to this fatal result of inhalant abuse.
