If your teen is spending time with friends who use marijuana, it can be hard to know how serious the risk is, what signs to watch for, and how to talk about it without pushing them away. Get clear, parent-focused guidance for this exact situation.
Share what you’re seeing—like changes in behavior, who they’re spending time with, or whether this is happening at school or after school—and get personalized guidance on how to respond calmly and effectively.
Many parents search for help because they’ve learned their kid’s friends are smoking weed or they suspect their teen is around friends smoking marijuana. The most effective response is steady and informed: understand the level of exposure, look for patterns instead of one-off moments, and start a direct but respectful conversation. This page is designed to help you figure out what to do if your child’s friends smoke weed, how to keep your child away from risky situations when needed, and how to stay connected while setting clear expectations.
Your teen starts spending time with new peers, becomes vague about where they are, or avoids introducing friends you used to know well.
You may notice secrecy, irritability, changes in motivation, or a sudden drop in openness after hanging out with certain friends.
Parents dealing with friends smoking weed in high school often notice skipped activities, slipping grades, or more unsupervised time after school and on weekends.
Start with what you know and ask calm, specific questions. Try to understand how often your teen is around weed, who is involved, and whether they feel pressure to join in.
Your teen should know your rules about being around substance use, getting in a car with someone impaired, and leaving situations that feel unsafe.
The goal is not one perfect talk. Ongoing conversations make it more likely your teen will tell you the truth and come to you when something changes.
Know where your teen is, who they’re with, and what the plan is. More structure and check-ins can reduce risk without turning every interaction into a confrontation.
Make sure your teen has a no-questions-asked way to call or text for a ride if friends start using weed or the situation becomes unsafe.
If certain friendships or settings repeatedly involve marijuana, it may be appropriate to limit access, change routines, or require more supervised plans.
Start by focusing on exposure, not just use. Ask how often weed is present, whether anyone drives after using, and how your teen handles pressure. Even if your teen is not using, being around friends who smoke weed can still create safety and judgment concerns.
Look for patterns such as secrecy about plans, sudden changes in friends, avoiding details about where they were, or behavior shifts after spending time with certain peers. One sign alone does not prove anything, but repeated changes are worth addressing.
Begin with clear expectations and more supervision rather than immediate ultimatums. Limit high-risk settings, require more specific plans, and offer alternatives that keep your teen socially connected. If a friendship consistently involves marijuana, stronger boundaries may be necessary.
Yes. In high school, access, peer pressure, rides with other teens, and unsupervised time can increase risk. Parents often need a more active plan around transportation, parties, after-school time, and communication with other adults.
