Marijuana Addiction Case Study: Cannabis Dependence, Treatment and Recovery
Marijuana Addiction Case Study: Patient Background
This marijuana addiction case study follows Aman (name changed), a composite example that reflects how cannabis dependence commonly develops and how it is assessed and treated at Calida Rehab. The details are illustrative and do not describe any one identifiable person.
Aman is a 24-year-old junior analyst from Thane. He lives with his parents and his younger sister. He first tried cannabis in college at a friend’s gathering and began smoking on weekends. Over five years the use became daily. By the time his family brought him to Calida Rehab he was smoking several times a day, often before leaving for work. His performance reviews were slipping, he had borrowed money from friends, and he had dropped most of his old interests. His family described him as quiet, irritable and always tired.
Before the case itself, a short note. Marijuana is made from the dried flowers and leaves of the cannabis plant and is known in India as ganja, charas or bhang, depending on the form. Its main active chemical, THC, acts on the brain’s reward and memory systems. Regular use can lead to cannabis use disorder, where a person cannot stop even though it is causing harm. Many people believe marijuana is harmless or not addictive. For some people it is both. For the full picture, read our page on marijuana addiction treatment.
Symptoms: How Marijuana Addiction Showed Up
Marijuana addiction is often missed because the signs build slowly and many people see the drug as harmless. The signs below are common.
Signs of dependence
- Using more often or for longer than planned
- Strong cravings, or spending a lot of time getting and using it
- Needing more to get the same effect (tolerance)
- Unsuccessful attempts to cut down or stop
- Continuing to use despite problems at work, in studies or at home
- Giving up hobbies, friends or responsibilities
Withdrawal when stopping
- Irritability, anger or restlessness
- Anxiety and low mood
- Trouble sleeping and vivid dreams
- Reduced appetite
- Headache, sweating, stomach pain or shakiness
Effects on daily life
- Poor memory, poor concentration and low motivation
- Falling work or study performance
- Money problems and secrecy
- Strain in family relationships
- Anxiety, suspiciousness or low mood
In this case: Aman described using within an hour of waking and needing it to fall asleep. He had tried to quit twice, but each attempt lasted about three days. He became irritable, could not sleep, lost his appetite and felt anxious, and then started again to feel normal. He forgot tasks, missed deadlines and slowly stopped meeting friends who did not use. He said marijuana helped him relax, but he felt more anxious on the days he could not get it.
Doctors do not go by a single symptom. Under the DSM-5 criteria, cannabis use disorder is diagnosed when a person shows at least two of eleven listed signs within a year. Two to three signs is mild, four to five is moderate and six or more is severe.
Why Marijuana Addiction Often Goes Unnoticed
Many people are not diagnosed for years. Marijuana is a plant, so it is often seen as natural and safe. People can keep going to work or college while using, and families may see the changes as laziness, a phase or stress. Alcohol and tobacco are frequently used alongside it, which hides the picture further. Today’s cannabis products can also be stronger than those used in the past, which raises the risk.
Regular heavy use that starts in the teens or early twenties is linked with problems in memory and learning, and with anxiety and low mood. In some people who are already vulnerable, it can bring on psychosis. Untreated use can lead to job loss, money problems, accidents while driving and conflict at home. The sooner it is recognised, the less damage builds up.
In this case: Aman’s family assumed it was a phase and that he was simply tired from work. He hid how much he used. The first real alarm came when his manager gave him a written warning after he missed a client report, and when his sister noticed he could not go a day without it. For years he had believed it was only weed and that he could stop whenever he wanted. That belief delayed help.
Diagnosis: How Cannabis Use Disorder Was Assessed at Calida Rehab
There is no single test that confirms addiction. The diagnosis is made by a psychiatrist through a careful clinical assessment. At Calida Rehab this typically includes:
- A detailed clinical interview about how long, how often and in what form cannabis is used, and how it has affected life
- Screening tools, such as the Cannabis Use Disorders Identification Test (CUDIT-R) or the ASSIST questionnaire
- A physical and medical check to look at general health, sleep, weight and any breathing problems from smoking
- A urine drug screen, which can confirm recent use but cannot show addiction on its own. In regular heavy users, THC traces may stay detectable for days to weeks.
- Screening for other substances, including alcohol, tobacco and other drugs
- Mental health screening for anxiety, depression, sleep problems and any psychotic symptoms
- Input from a family member, with the person’s consent
That mental health check matters. Cannabis use and mental health problems often feed each other, and treating only one leaves the person struggling. See our pages on anxiety disorder, our depression case study and our drug abuse case study to see how these conditions can overlap.
Result in this case: Aman was diagnosed with severe cannabis use disorder, along with anxiety symptoms, poor sleep and regular nicotine use. He had no psychotic symptoms. For Aman, learning that this was a treatable disorder and not a weakness of character was the first real turning point.
Treatment Plan for Marijuana Addiction
No single treatment suits everyone. At Calida Rehab the plan is built after the assessment, and the family is involved when the person agrees. Most plans combine the following.
Supervised withdrawal care. Marijuana withdrawal is usually not dangerous, but it can be uncomfortable enough to push a person back to using. Symptoms usually begin within a few days of stopping, are strongest in the first week and settle over two to three weeks. The team monitors sleep, mood, appetite and cravings, and may use short-term, symptom-based medicines only when the psychiatrist feels they are needed. Read more on our detoxification page.
Therapy as the core of treatment. At present no medicine is approved specifically for cannabis addiction, so behavioural therapy does most of the work. It helps the person understand why they use, handle cravings and build a life that does not depend on it.
Treatment of other conditions. Anxiety, low mood, poor sleep and nicotine or alcohol use are treated alongside the cannabis use.
Family involvement. Families learn what addiction is, how to respond to cravings and slips, and how to rebuild trust without blame.
Lifestyle. Fixed sleep and wake times, regular exercise, balanced meals and planned free time fill the gap that marijuana leaves behind.
In this case: Aman joined a structured residential programme of about three to four weeks. The first week was medically supervised. His withdrawal was mostly irritability, poor sleep and low appetite, which were strongest in the first few days and improved steadily. Short-term, closely monitored support was used for sleep and anxiety. He then moved into a daily routine of therapy, exercise and group sessions. His parents and sister joined family sessions to understand what he was dealing with.
Therapies Used in This Marijuana Addiction Case Study
The therapies below were part of Aman’s plan and are commonly used for cannabis use disorder.
- Motivational Enhancement Therapy (MET): helps the person explore mixed feelings about quitting and build their own reasons for change, instead of being pushed into it
- Cognitive Behavioral Therapy (CBT): identifies triggers such as boredom, stress and evenings with friends who use, and teaches skills to handle cravings and negative thoughts. Read more on our CBT page.
- Relapse prevention planning: a written plan for high-risk situations, early warning signs and what to do after a slip
- Stress and sleep skills: relaxation, a fixed bedtime routine and healthier ways to wind down, so that marijuana is not the only way to relax
- Family therapy: sessions that help families communicate, set healthy limits and rebuild trust. See our family therapy page.
Follow-Up Care After the First Phase
Addiction is a long-term condition, so care does not end when the first phase of treatment ends. Follow-up usually includes:
- Regular counselling sessions, with more frequent sessions in the first months and wider gaps later
- Review of sleep, mood and anxiety, with treatment adjusted if needed
- Periodic drug screens, only with the person’s consent, as an honest check and not as a punishment
- Booster sessions to refresh relapse-prevention skills when cravings or triggers return
- Support in returning to work or studies and rebuilding a routine
- Continued involvement of the family, where the person agrees
A slip does not mean treatment has failed. It is a signal to get support quickly. Our drug addiction treatment page explains what ongoing care looks like.
Outcome: What Recovery Looks Like With Marijuana Addiction
What changed for Aman over the first three months:
- Cannabis use: he stopped using. He had two strong craving episodes and handled both with the plan he had practised.
- Sleep and mood: his sleep returned to normal within a few weeks, and his anxiety settled.
- Work: he returned to his job. His manager noticed better focus and fewer missed deadlines.
- Family: trust rebuilt slowly. Home conversations became calmer, and his sister said she had her brother back.
- Money and time: he began repaying what he had borrowed and took up cricket and the gym again.
It is worth being clear about what recovery means. It is not only stopping marijuana. It is a person who sleeps, works and relates to others without it, who understands their triggers, and who knows what to do when a hard phase returns.
What the first six months of treatment usually look like
- Month 1: assessment, supervised withdrawal care, a short structured programme and a written plan.
- Months 2 and 3: therapy skills build. Sleep and mood are reviewed. Family sessions continue.
- Months 4 to 6: gains settle in. The team reviews what is working and what still needs support.
This is a general guide. Every person moves at a different pace.
Key Takeaways from This Marijuana Addiction Case Study
- Marijuana can be addictive. It is not just a habit or a lack of willpower.
- Withdrawal is real. It is usually not dangerous but can be hard enough to cause relapse, so supervised support helps.
- Therapy is the core of treatment, since no medicine is approved specifically for cannabis addiction.
- Anxiety, low mood, poor sleep and other substance use often sit alongside cannabis use and need treatment too.
- A slip is not a failure. Getting help quickly after one is what protects recovery.
