Drug and alcohol use tends to begin at an early age. It is a fact, your child will be exposed to drugs and alcohol in some form or another throughout school and beyond. This is no reason to panic, but to keep a lookout and protect your child when you see any of the signs your kid is using drugs.

How Do I Know If My Kid Is Doing Drugs

If your child’s grades started to plummet around the time you noticed changes in their behavior, you may be looking at one of the common consequences of drug addiction or abuse. If your kid goes from being a straight-A student to getting F’s or D’s, something’s changed. Of course, it could be linked to a number of factors other than kids doing drugs, so make sure you explore other causes.

The following are 10 signs your teen is using drugs:

1. The 1000-Yard Stare

Glazed expressions may be a sign of addiction, but with some teens, it’s hard to read signs your kid is on drugs. Teenagers and twenty-somethings tend not to be the most communicative of creatures, but if your kid starts looking stoned all the time and is accompanied by any of the other factors listed, it’s entirely possible he or she is stoned.

2. Abandoning Friends or New Friends

Fairly common throughout the teenage years, but it could have a more sinister implication. If your kid starts hanging out with a different crowd who smoke and so on, it could be a phase, but it could be linked to drugs.

3. Abandoning Social Activities

Another potential sign of drug abuse. Kids who are doing drugs would rather do that than almost anything else. Again, interests change throughout your kid’s formative years, so tread lightly. It might just be related to a change of tastes.

4. Evasive Answers to Questions

If your kid can’t tell you for certain where they’ve been, that can sometimes mean they’re using drugs. Monitoring them while they’re out might seem like meddling, but any child living under your roof is subject to terms and conditions that you set.

5. Moodiness and Changes in Behavior

Moodiness and abrupt changes in behavior are quite common with kids who take drugs. The moody teen is a stereotype, as it turns out, is true. But if you notice that your child is jittery in the morning and calmer in the evening, these could be signs your child is on drugs.

6. Memory Problems

Issues with memory or an inability to pay attention can sometimes be signs of drug use in teens. While everyone forgets things here and there, if your child has problems remembering basic things, you might need to examine this. Of course, it could also be a sign of medical issues, such as ADHD.

7. Unexplained Injuries

A child with unexplained injuries can be related to drug or alcohol use. Just as above, however, they could also be related to medical issues or even bullying.

8. Missing Objects or Money

Missing objects around your house might mean that your child might be stealing to fund a habit. Tread lightly here, as it’s just as likely to be a partner or friend stealing them.

9. Weight Changes

An increase or decrease in weight is a normal part of teen life, but rapid fluctuations could indicate an addiction. Some teens neglect to eat due to drugs or spend lunch money on addiction rather than eat. If your child was always heavy and then, suddenly seems to have lost a great deal of weight, you should investigate further.

10. Running with the Wrong Crowd and Staying Out Late

Staying out late with friends might seem like typical teenage habits, but in combination with things listed above, it’s possible that this could be an indication of drug abuse. Of course, it’s most likely that the drug of choice is alcohol in this case. A parent’s instincts are usually pretty good. If your kid seems to be running with the wrong crowd, you should start monitoring the child’s behavior, recreational habits, and time out of the house as well as using some investigation methods for spotting signs your kid is using drugs.

How to Spot The Signs Your Kid is Using Drugs

Most parents we meet tell us that they wish they knew the signs their kid was using drugs, and want to know common signs like how to tell if your kid is high. With a bit of training, you can begin to recognize the warning signs. First off, experts agree that you should have some sense of what’s going on by examining certain elements of their daily life and most of all, use your senses.

If you suspect that your child is using drugs, a process of observing, investigating and monitoring your child is the first step. If you’re seeing strong signs of addiction, the next discussion with your child should be very direct – ask them point-blank if they’re using substances. If you have any doubt, go to a local drug store and buy an in-home drug test kit. It is your right as a parent to demand that any child living under your roof submit to a drug test. The following list should help you as a parent know how to tell if your kid is on drugs. 

Use Your Nose to Find the Signs Your Teen is Using Drugs

One sniff of your kid’s laundry should tell you a lot. Marijuana and cigarettes have strong odors that are difficult to hide. At the very, very least, you should be checking your child’s laundry. Odd smells are a pretty good reason to arouse your suspicion. It could be a new interest in deodorant or a heady smell of marijuana-laced smoke. If you don’t know what marijuana smells like, it’s time to educate yourself. We don’t suggest smoking it yourself, but you may be able to ask a friendly cop to show you a sample. 

Look Them in the Eyes

When your child gets home after going out with her friends, take a close look. Pay attention to his or her eyes. Eyes will be red and heavy-lidded, with constricted pupils if they’ve used marijuana. Pupils will be dilated, and he or she may have difficulty focusing if they’ve been drinking. In addition, red, flushed color to the face and cheeks can also be a sign of drinking.

Do They Have a Car?

Check their car, too. Smell the inside of the car, check the ashtray (if your car has one) and look for evidence of drug paraphernalia, marijuana residue, rolling papers or other items that are questionable. Check every pocket, in every corner, under the floormats front and rear, in all the armrest pockets and in the trunk, including under the trunk mat.

Watch for Mood Changes

How does your teen act after a night out with friends? Are they loud and obnoxious, or laughing hysterically at nothing? Unusually clumsy to the point of stumbling into furniture and walls, tripping over their own feet and knocking things over? Sullen, withdrawn, and unusually tired and slack-eyed for the hour of night? Do they look queasy and stumble into the bathroom? These are all signs that they could have been drinking, using marijuana or signs of pill addiction.

Check their Bedroom

This includes drawers, under the bed, in their desk, in high, hard to reach places and inside of any tin, box, bag, container, including video game boxes, DVD cases, and so on. Paraphernalia for drug use include roll-ups and tin boxes. For other drugs, it could be syringes and burnt teaspoons. If you see a tin box, open it and take a sniff. If it smells like tobacco, it probably is. When you find something that has an unidentifiable smell, ask your kid about it.

Look for Signs of Tobacco Use or Vaping Pen Use

When children or young adults start smoking or vaping, chances are high that they learned it from someone else. If not a parent, then a peer. And if your child’s peers are using tobacco or vaping, there’s a good chance that they may be using marijuana. Smoking and marijuana usage are gateways to further experimentation with illicit substances. These are also great steps to take if you’re also wondering, “how do I know if my child is exposed to drugs”.

These things are the bare minimum you should be checking. If you’re not willing to do at least these things, you’re not doing all you could be doing. Remember that any child living under your roof is subject to your rules and conditions. They have no rights and no say as to what you as a parent deem to be acceptable when it comes to monitoring their behavior for signs your teenager is on drugs. You must also remember that you’re their parent – not their friend – and as such, there should be little discussion or negotiations as to what you as a parent will accept.
