The document discusses three scenarios where drug testing a child could be considered proactive parenting rather than snooping:
1. For proactive parents wanting to deter drug use, telling the child about regular and random drug tests can help the child avoid peer pressure situations by being accountable to drug tests.
2. For suspicious parents seeing signs of potential drug use, secret drug tests without telling the child can provide honest answers to confirm or ease suspicions.
3. For parents of a confirmed former drug user allowing the child to return home, secret drug tests can give reassurance the household remains drug-free as expected by enforcing consequences if the child uses drugs again.
