Key Takeaways
- Roughly 22% of people who use cannabis develop cannabis use disorder. Among young people who use it weekly or more, that figure rises to about 33%.[2]
- Families usually notice behaviour before they notice the substance. Changes in sleep, money, mood and secrecy tend to come first.
- Withdrawal is real. Symptoms typically begin 24 to 48 hours after stopping and peak between days 2 and 6.[3]
- There is no approved medicine for cannabis use disorder. Talking therapies are the main treatment, and they work.[7]
- Noticing early matters more than knowing what to say perfectly.
You have probably asked yourself the question more than once. Is this just a phase, or is something actually wrong?
Ā
Maybe it started small. A different set of friends. A locked door. Money that does not add up. And now you find yourself watching someone you love, trying to work out whether what you are seeing is ordinary growing up, or something that needs help.
Ā
About 2.8% of people in India currently use cannabis. That works out to roughly 3.1 crore people. [1] Most of them will never develop a problem with it. Some will.
Ā
This guide is about telling the difference.
What is cannabis addiction?
QUICK ANSWER
Cannabis addiction is a medical condition in which a person keeps using cannabis even though it is causing problems in their life, and finds they cannot cut down or stop when they try. It is known clinically as cannabis use disorder, is recognised in the DSM-5, and sits on a range from mild to severe. It is not a matter of willpower or character.
Cannabis addiction is a medical condition in which a person keeps using cannabis even though it is causing problems in their life, and cannot cut down when they try. About 2.8% of people in India currently use cannabis, and roughly 22% of people who use it go on to develop cannabis use disorder.
Ā
If you would rather talk it through than read on, the team at Abhasa Rehab and Wellness answers questions like these every day, with no obligation to do anything afterwards.
What Does Cannabis Addiction Actually Look Like?
In short: Cannabis addiction is not about how much someone uses. It is about whether they can stop. When cannabis starts taking priority over sleep, work, studies or relationships, and the person keeps using anyway, that pattern is what doctors call cannabis use disorder.
Ā
Here is the thing most families get stuck on. They try to measure the problem by counting. How many times a week? How much does it cost? Those numbers matter, but they are not the deciding factor.
Ā
The clinical picture rests on control, not quantity. The DSM-5 describes substance use disorders around a set of patterns: using more than intended, wanting to cut down but not managing it, spending a lot of time getting or recovering from the substance, and continuing despite clear harm [5]
Ā
Someone can use cannabis every weekend for years and not meet a single one of those. Someone else can use far less and meet most of them.
Ā
Sound familiar? That gap between “uses a lot” and “cannot stop” is the whole question. You can read more about how cannabis affects the body and mind on our cannabis page.
The Behavioural Signs Families Notice First
Sleep is often the first thing to move. Someone who used to be up by eight is now sleeping until two, then awake half the night. Meals get skipped or become erratic. Appointments slide. College attendance drops in a way that gets explained away each time, with a different reason each time.
Ā
Small things stop getting done. Not dramatically. Just steadily.
Interests fall away. A person who used to play cricket every Sunday stops going, and does not really replace it with anything. Irritability rises, especially when plans get in the way of using. Flat is the word families often reach for. Not sad exactly. Just flat.
Ā
You may also notice a strange defensiveness about the topic itself, well before anyone has accused them of anything.
Money is often the clearest signal, because it leaves a trail. Cash disappears in amounts too small to confront but too regular to ignore. Requests to borrow become routine. Things go missing and get explained.
Ā
Alongside it comes a change in openness. Phones turn face-down. Rooms get aired out. Questions get answered a beat too quickly.
Withdrawal from family life tends to come last, and it hurts the most. Meals taken alone. Family functions skipped. A social circle that has quietly narrowed to people who use.
Ā
“One thing I’ve noticed over the years is that families often want to help but don’t know how. Learning the difference between enabling and supporting can change everything.” –Ā Dr. Naveen Kumar, Consulting Psychiatrist, Abhasa Rehab and Wellness
Ā
None of these signs on its own proves anything. Any one of them can have a completely different explanation. It is the cluster, and the direction of travel over months, that tells you something. Our guide to theĀ stages of drugĀ addictionĀ sets out how this usually unfolds.
Ā
If you are recognising more than a few of these, that is worth taking seriously. It does not mean the worst.
Is This Heavy Use, or Actual Dependence?
In short: Regular use becomes dependence when control goes. The markers are needing more for the same effect, feeling unwell when stopping, repeated failed attempts to cut down, and continuing even after real damage to work, health or relationships.

Read the right-hand column honestly. Not the worst day you can remember, but the ordinary pattern of the last six months.
Ā
One caution, and it matters. This table is a way of organising what you are seeing. It is not a diagnosis, and neither you nor an article can make one. A proper assessment means sitting with the person, and only a qualified professional can do it.
Ā
If you would like that assessment done properly, Abhasa Rehab and Wellness offers a confidential consultation.
What Cannabis Withdrawal Looks Like
People are often surprised that cannabis has a withdrawal syndrome at all. It does, and it is one of the reasons stopping is harder than it looks from outside.
Ā
Cannabis withdrawal symptoms usually begin 24 to 48 hours after the last use, and most peak between days 2 and 6. In people who have been using heavily, some symptoms can carry on for three weeks or more.
Ā
In people who have been using heavily, some symptoms can carry on for three weeks or more [3]. A study tracking people through detoxification found the same sharp peak in the days 2 to 6 windowĀ [4].
Ā
What it tends to look like: trouble sleeping, vivid dreams, irritability, low appetite, restlessness, and a low mood that lifts as the weeks pass.
Ā
Here is why this matters for you. Someone who says “I tried to stop and I felt terrible, so clearly I need it” is not making an excuse. They are describing withdrawal. And withdrawal is a reason to get support, not a reason to keep going. Our detoxification page explains how this is managed safely.
Ā
Knowing this in advance can change how the next conversation goes.
Why Cannabis Addiction Is Easy to Miss in Indian Families
Cannabis occupies an unusual place here. Bhang appears at festivals. It is spoken about as traditional, natural, harmless. That cultural familiarity does something specific. It makes the early signs easy to explain away, for everyone involved.
Ā
There is a second thing, less obvious. The cannabis available now is not the cannabis of a generation ago. Analyses of samples collected over time show that THC concentrations have risen substantially, while CBD has stayed flat or fallen [6]. So a parent comparing today against their own memory of the 1990s is comparing two different substances.
That is worth sitting with. The same closeness that delays a family from acting is the closeness that makes recovery work once they do.
Ā
For more on the plant itself, see theĀ potency of cannabisĀ and our article onĀ bhang.
Ā
You do not need to have handled this perfectly so far. Almost nobody does.
When Cannabis Sits On Top of Something Else
Often cannabis is not the whole story. It may be sitting on top of anxiety, low mood, or sleep problems that came first, with cannabis being used to manage them.
Ā
There is also a recognised link between heavy cannabis use, particularly starting in adolescence, and increased risk of mental health problems including psychosis [12]. We cover this properly in marijuana and mental illnessĀ andĀ cannabis for mental health.
Ā
When both things are present, treating only one tends not to hold. That combined approach is what dual diagnosis care is for.
Ā
Worth mentioning to whoever does the assessment if you have noticed both.
What Actually Helps
Let me be direct about the treatment picture, including the part that surprises people.
Ā
There is currently no approved medicine for cannabis use disorder. Talking therapies are the main treatment, and the approaches with the strongest evidence are cognitive behavioural therapy, motivational enhancement therapy, and contingency management.
Ā
A Cochrane review of pharmacotherapies for cannabis dependence found none approved for treatment[7], and more recent syntheses reach the same conclusion[8]. Psychological treatment remains the primary approach, and the evidence for it is reasonable [8].
Ā
The approaches with the best support are cognitive behavioural therapy, motivational enhancement therapy, and contingency management, often combined [11][9]. Contingency management in particular has a growing evidence base for cannabis specifically [10].
What the path usually looks like
Write down what you have actually observed, with rough dates. Not conclusions. Observations
Pick a calm moment when nobody is using or angry. Lead with what you have seen and how you feel, not with an accusation.
A qualified professional works out what is going on, including anything underneath it.
Structured talking therapy, with support for withdrawal in the early weeks where needed.
Relapse is common and is not failure. Ongoing support is what holds progress in place.

Step one is genuinely the whole start. You may already have done it, just by reading this far.
How Abhasa Rehab and Wellness Supports Families
Abhasa Rehab and Wellness is a residential rehabilitation and mental health facility with centres in Coimbatore, Tamil Nadu, and in Karjat, Maharashtra.
Ā
Assessment and treatment are overseen by qualified psychiatrists, and families are involved in the work throughout.
Ā
Care is led clinically. Assessment and treatment are overseen by qualified psychiatrists, including Dr. Naveen Kumar, MBBS, DPM (Psychiatry), a consulting psychiatrist with over 20 years of experience in addiction psychiatry and dual diagnosis. That matters here specifically, because cannabis so often arrives alongside anxiety, depression or sleep problems that need treating at the same time.
Ā
Families are treated as part of the work, not as visitors to it. Support includes helping relatives learn the difference between enabling and supporting, which is usually the hardest skill to build and the one that changes the most.
Ā
If you would like to talk to someone about what you have been noticing, our family support page is a starting point, and you can also read about our Coimbatore centre.

There is no pressure to commit to anything by asking a question.
Frequently Asked Questions
Experimenting tends to be occasional, open, and does not reshape daily life. Dependence shows up as loss of control, tolerance, and continued use despite clear problems. If the pattern has been building over months rather than weeks, that is worth a professional assessment.
Yes. Around 22% of people who use cannabis develop cannabis use disorder, and among young people using weekly or more the figure is closer to 33%.[2] It is less likely than with some other substances, but it is far from rare.
Natural and habit-forming are not opposites. Tobacco is a plant too. Cannabis has a documented withdrawal syndrome and a recognised disorder in the DSM-5, which is about as clear as the evidence gets.
Choose a calm time, describe what you have noticed rather than what you have concluded, and speak about your own worry rather than their behaviour. “I have noticed you have not been sleeping and you have missed college three times this month, and I am worried” lands differently from “you are always high”.
It varies a great deal with how often someone uses, their body composition and the test used. Occasional use may clear within days, while heavy regular use can be detectable for several weeks. A testing laboratory or doctor can give a proper answer for a specific situation.
The picture is mixed and depends heavily on age at first use and how heavy the use has been. Starting young and using heavily carries the most risk, including a raised risk of mental health problems. Many effects improve after sustained abstinence.
Forced admission is a last resort with real legal and ethical limits, and it often damages trust. In most cases a skilled assessment and a family that has learned how to hold boundaries achieves more. Talk to a professional about your specific situation before acting.
Good programmes involve the family throughout, with sessions aimed at rebuilding communication and setting boundaries. Recovery holds far better when the household changes alongside the person.

Taking the Next Step
You do not have to be certain to act. That is the part most families get wrong, waiting for proof before making a phone call.
What you have been noticing is information. It may turn out to be nothing serious. It may turn out to be something that responds well to treatment, which cannabis use disorder generally does. Either way, you are better off knowing.
Nobody manages this conversation perfectly. The families who do well are not the ones who said the right words. They are the ones who stayed in the room.
Whenever you are ready, Abhasa Rehab and Wellness is here to talk it through.
