Supporting Someone Who's Quitting Cannabis

Your Role Matters More Than You Think

Research consistently shows that social support is one of the strongest predictors of successful recovery from substance use. A 2020 review in Substance Use & Misuse found that people with strong family and friend support were significantly more likely to maintain changes in their cannabis use over time.

But supporting someone through this process can be confusing, exhausting, and emotionally complicated — especially if you've never been through it yourself. This page is here to help you understand what they're going through and give you practical tools to help without burning out.

What They're Actually Experiencing

Cannabis withdrawal is real. It's recognized by the DSM-5 and affects roughly 47% of regular users who stop. Understanding what your person is going through can help you respond with patience rather than frustration.

Common Withdrawal Symptoms

• Irritability and mood swings — This is the most common symptom. It peaks around days 2-6 and can last 2-4 weeks. It's not about you.
• Insomnia and vivid dreams — Sleep disruption can be severe in the first 1-2 weeks. They may be exhausted and short-tempered as a result.
• Appetite changes — They may have little to no appetite for the first week or two. Don't push food, but make it available.
• Anxiety and restlessness — Cannabis was likely managing their anxiety. Without it, anxiety often surges before it settles.
• Physical discomfort — Headaches, sweating, and stomach issues are common in the first week.

How to Help: Practical Strategies

Do

• Ask how they want to be supported. Don't assume. Some people want check-ins; others want space. Ask: "What would be most helpful from me right now?"
• Be patient with irritability. Mood swings during withdrawal are neurological, not personal. Try not to take it personally, even when it's directed at you.
• Celebrate milestones. Day 3, week 1, month 1 — these matter. A simple "I'm proud of you" goes a long way.
• Keep cannabis out of shared spaces. If you use cannabis yourself, be mindful about where and when. Don't leave it visible or use it around them without asking if that's okay.
• Offer distraction. Suggest activities — walks, movies, cooking together, games. Boredom is a major trigger for cravings.
• Be available without hovering. Let them know you're there. Then give them space to come to you.
• Learn about what they're going through. You're already doing this by reading this page. Understanding the science of dependence helps you respond with empathy rather than judgment.

Don't

• Don't minimize their experience. "It's just weed" is one of the most harmful things you can say. Cannabis dependence is a recognized medical condition with real neurological withdrawal.
• Don't set ultimatums (unless safety is at stake). Ultimatums create shame, and shame is a relapse trigger. Support works better than pressure.
• Don't monitor or police their behavior. You're a partner or friend, not a probation officer. Trust and autonomy are essential for lasting change.
• Don't take relapse personally. Relapse rates for cannabis use disorder are comparable to other chronic conditions. A slip doesn't mean they've failed or that your support doesn't matter.
• Don't expect instant personality change. Recovery is gradual. They may not suddenly become the person you remember from before they started using — and that's okay.

When They Relapse

Relapse is common — not a sign of failure. Research shows that most people who successfully quit cannabis have multiple attempts before it sticks. If your person relapses:

• Stay calm. Your reaction sets the tone. Anger or disappointment (even if you feel those things) can drive them away from being honest with you.
• Don't say "I told you so" or express frustration about "wasted effort." Every quit attempt builds skills and insight.
• Ask what happened — with curiosity, not accusation. What triggered it? What can be different next time?
• Reaffirm your support. "I'm still here. What do you need?" is powerful.

Taking Care of Yourself

Supporting someone through recovery can be emotionally draining. You matter too, and neglecting your own wellbeing helps no one.

• Set boundaries. You can be supportive without being responsible for their recovery. It's okay to say "I need a break from this conversation right now."
• Talk to someone. Whether it's a friend, therapist, or support group, you need space to process your own feelings about this.
• Recognize what you can and can't control. You can offer love, patience, and support. You cannot make someone recover. That distinction is critical for your own mental health.
• Watch for codependency. If their recovery becomes your entire focus — if you're more invested in their quitting than they are — that's a signal to step back and seek support for yourself.

Support Groups for Family and Friends

Mar-Anon Family Groups

Mar-Anon is a 12-Step fellowship specifically for people affected by someone else's marijuana use. Modeled on Al-Anon (for families of alcoholics), Mar-Anon provides a structured program of recovery for family members and friends.

Mar-Anon helps you:

• Understand that you didn't cause, can't control, and can't cure someone else's addiction
• Connect with others who understand exactly what you're going through
• Develop healthy boundaries and coping strategies
• Focus on your own recovery and wellbeing

Meetings are available both in-person and online. Visit mar-anon.com to find a meeting.

Al-Anon Family Groups

While Al-Anon was originally created for families of alcoholics, many groups welcome anyone affected by a loved one's substance use, including cannabis. Al-Anon has a much larger network of meetings than Mar-Anon, so if there isn't a Mar-Anon group near you, Al-Anon may be a more accessible option.

SMART Recovery Family & Friends

SMART Recovery Family & Friends offers a science-based, non-12-step alternative. Their program teaches evidence-based skills for coping with a loved one's substance use, including communication strategies, self-care, and how to motivate change without enabling.

Therapy

Individual or couples therapy with a therapist experienced in substance use issues can be invaluable. Look for therapists who specialize in family systems, codependency, or substance use counseling. See our guide on Finding a Therapist.

For Parents

If you're a parent of an adult child who is quitting cannabis, the dynamic adds extra complexity. A few additional considerations:

• Respect their autonomy. Even if you're financially supporting them, their recovery needs to be their choice and their process.
• Resist the urge to manage. Parental instinct to fix things can undermine their sense of agency — the very thing they need to build for lasting recovery.
• Address your own feelings. Guilt ("Did I cause this?"), anger, and grief are all normal. A therapist or support group can help you work through these.
• Be honest about your own relationship with substances. If you use cannabis or drink heavily yourself, consider how that affects the environment.

For Partners

Living with someone who is quitting cannabis means living with withdrawal symptoms, mood changes, and a shifting relationship dynamic. Some specific guidance:

• Expect the relationship to change. Cannabis may have been central to how you spent time together. You'll need to discover (or rediscover) what your relationship looks like without it.
• Communicate openly. "I noticed you seem frustrated today — is there anything I can do?" is better than walking on eggshells.
• Be prepared for emotions to surface. Cannabis often suppresses emotional processing. When it's removed, unresolved feelings may come flooding back — about your relationship, their life, everything.
• Consider couples counseling. If cannabis use has created trust issues, resentment, or communication breakdowns, professional support can help you rebuild together.

Social support is consistently identified as a significant predictor of treatment outcomes for substance use disorders, including cannabis use disorder. Family involvement in recovery processes is associated with improved treatment retention and reduced relapse rates.
