Drug Testing for Parents and Schools: What to Know

Home and school drug testing is a personal decision, and it works best as part of a larger conversation, not a replacement for one. Here is what parents and schools should consider before testing.

For parents

Talk first

Experts generally recommend talking with your teen before testing, and involving your child's doctor. Testing without warning can damage trust. Many families use testing as part of a clear agreement, for example after a teen has already used substances, and focus on safety rather than punishment.

Choosing a test

  • A 12 panel cup covers the most common substances, including alcohol (EtG).
  • If you are concerned about a specific substance, a single-drug strip such as THC or K2 is inexpensive.
  • Vapes and edibles containing THC, including delta-8, will show up on a THC test. See CBD and delta-8.

If a test is positive

Stay calm, and remember that an instant test is preliminary. Ask about any medications, and consider confirming the result with a laboratory. Talk to your child's doctor or a counselor about next steps.

For schools

In the United States, the Supreme Court has allowed public schools to randomly test students who take part in athletics and other extracurricular activities. Schools that test typically do so under a written policy approved by the board, with parental consent, confidentiality protections and a focus on getting students help. State law and district policy also apply, so review them with your district's legal counsel.

  • Use a written, consistently applied policy and get parental consent.
  • Keep results confidential and separate from academic records.
  • Confirm positives with a laboratory before any consequences.
  • Pair testing with counseling and support, not only discipline.
