When Teens Lie About Drugs: A Guide for Parents

If Tom Hedrick could change one thing about teen drug use, he would reduce the time it takes between a parent’s first hunch that something is wrong and the child getting treatment. The fact that teens lie about drugs, and parents believe them, delays treatment, says Hedrick, a founding member of The Partnership for a Drug-Free America.

Brian and Julie Unwin have heard a lot of lies, both from their son and through other parents in their support group. A few examples:

  • “Other people were smoking marijuana. I must have inhaled some by accident.”
  • "My friend had a cold, so I gave him our bottle of cough medicine."
  • “I was the only one at the party who wasn’t drinking, but they arrested all of us.”
  • “I ate a poppy seed muffin. That must be why the drug test came back positive.”

The Unwins’ teenage son lied and manipulated them for four years until he got sober. And they, like many parents, had a hard time accepting that reality. “When you raise a child, when you hold him in your arms as an infant, you want to believe him. No family wants to go through this,” says Brian.

This article explores the lies teens tell about drugs and what parents can do to get over their hurt and anger to keep their child safe.

A group of researchers wanted to know how common it is for teens to lie about drugs. They asked 400 teenagers if they used cocaine, then took hair samples to test for traces of the drug. Even though they knew their answers were private, and that the drug test would prove them right or wrong, most teens who had cocaine in their systems denied using it. The hair samples revealed drug use 52 times more often than the teens admitted.

The fact that teens lie even when they know they’ll get caught doesn’t surprise Mason Turner, MD, chief of psychiatry at Kaiser Permanente San Francisco. “Most teens don’t think about what comes next,” he tells WebMD. “Concerns about the future don’t enter into their decision making.”

If your child is lying about using drugs or alcohol, looking the other way is a dangerous mistake. Study after study shows that parents’ involvement plays an important role in preventing adolescent drug use. And the earlier problem is addressed, the better your chances of containing potential damage. Here are six things you can do.

1. Trust your instincts.
Turner sees many parents discount their concerns about their child’s behavior. They say things like, “I’m probably just being an obsessive parent.” Or “Maybe I’m being hypersensitive.” But parents know their children. “If a parent’s gut is telling them something is off, there has got to be a reason,” Turner tells WebMD.

If the cold or cough syrup in your medicine cabinet disappears or gets used up, ask about it. Over-the-counter cough medicines contain dextromethorphan, an ingredient teens can drink in excess to get high.

Cagey behavior may have a simple explanation or a serious cause. Perhaps your child is stressed over schoolwork. Maybe they had a fight with a friend. Or they could have a problem they’re afraid to talk about. Turner counsels parents to make it as easy as possible for their teens to talk to them. Start by asking what is going on. Talk about specific things you see and concerns you have, and then be ready to listen.

2. Educate yourself.
Julie Unwin saw her middle-school son become increasingly sullen and withdrawn. “In my gut I believed something was wrong,” she says. "But I thought, if he was using drugs I would see a physical sign.” The Unwins' son didn’t come home slurring or with bloodshot eyes because he wasn’t using alcohol or marijuana, at least not at first. There might have been signs, but his parents didn’t know what to look for.

Drugs rise and fall in popularity over time. It’s possible you have never heard of your child’s drug of choice. With time and research you can get to know the different substances available to kids today. The web sites drugfree.org or drugabuse.gov have drug guides that describe commonly abused substances and their effects.

3. Don’t take it personally.
If you find out your child is lying about drugs, you may see red. You may feel hurt, angry, guilty, and betrayed. All of these emotions are understandable. And none of them will help you help your child.

“First, recognize that lying is a normal teen behavior,” advises Turner. He goes on to say that normal or not, parents can and should teach their kids that lying is unacceptable. Your conversation with your child could cover the following ground:

  • Explore the reasons your child lied
  • Understand what is going on
  • Let your child know that lying is not OK
  • Talk about how to be honest in the future

4. Get help.
A lot of parents try to keep their child’s drug use within the family, Hedrick tells WebMD. “The idea that addiction reflects badly on the family keeps a lot of kids out of treatment until the problem is too big to ignore.”

Like diabetes or a broken bone, treating drug abuse requires expertise most parents don’t have. If your child is using drugs, you’ll have your hands full, even with a professional involved. Start by talking to your family doctor or pediatrician. The counselor at your child’s school may be able to recommend specialists or treatment centers that can help both you and your child.

5. Leave room to rebuild trust.
When parents don’t trust their kids, problems like drug abuse can snowball. Strained parent-child relations typically cast a negative tone on any and all interactions. Families tend do fewer things together, leaving kids fewer opportunities to feel connected to their parents. “Parents need to build a safe space for the child, while also defining boundaries and limits,” says Turner.

Try not to let the lies you’ve been told overshadow every conversation you have with your child. “So many kids in our groups say, ‘I never get a chance to talk. My parents cut me off all the time,’” says Hedrick. Open, two-way conversations can reinforce your child’s awareness of your family values and make the idea of drugs less appealing.

6. Expand your parenting style.
“A lot of parents are at one end of the spectrum or the other: overly permissive, or overly aggressive,” says Turner. Substance abuse requires a variety of parenting styles. Sometimes your child will need you to be warm and loving. Other times, you will have to enforce rules your child considers unfair.

Everyone interviewed for this article emphasized how important it is for parents to be their child’s parents, not their friends. There’s a significant difference.

  • Friends think it’s OK if another kid does drugs, puts themselves in danger, and lies about it.
  • Parents love their children and are willing to set limits and boundaries to keep them safe, no matter much strife it causes in the household.

The Unwins often had to do the opposite of what they considered good parenting while their son was going through treatment. “Instead of protecting our child and taking care of his needs, we had to put the onus and responsibility on him. We couldn’t let our emotions take over and try to fix everything,” says Brian.
