内容简介：
An Essential Series That Shows the Damage of Drugs from the Inside Out Research shows that drug abuse prevention efforts in the preteen years lead directly to lower rates of drug use during the teen years. But middle school readers are not easily swayed by oversimplified "just say no" messages. This series delivers its message in a dramatic and effective way: by telling--and showing--readers the harsh realities of the physical effects of drugs, alcohol, and tobacco.
