The best strategy for Sam's parents to protect him against substance abuse is to:
- **Explain the ill effects of substance abuse to Sam and avoid abusing substances themselves.** This strategy involves educating Sam about the dangers and negative consequences of substance abuse. By providing him with knowledge and understanding about the risks involved, along with setting a positive example by not engaging in substance abuse themselves, Sam's parents can help him make informed and healthy choices.
This approach promotes open communication, builds trust between parents and child, and empowers Sam to make responsible decisions regarding substance use. It emphasizes prevention through education and guidance, rather than reactive measures or enabling behaviors that could potentially lead to substance abuse issues.
