A lot of people believe marijuana is not habit-forming, so they are caught off guard when quitting leaves them irritable, anxious and unable to sleep. Cannabis withdrawal is a recognized condition, and it is one of the main reasons people who want to cut back find themselves reaching for marijuana again.
This article covers what cannabis withdrawal feels like, how long symptoms generally last, why today’s products may play a role, and how to know when it is time to get help.
Can You Really Have Withdrawal From Marijuana?
Yes. Regular, heavy cannabis use can lead to cannabis use disorder, which includes physical dependence for some people. THC, the main psychoactive compound in marijuana, acts on the brain’s endocannabinoid system, which helps regulate mood, sleep, appetite and stress. With frequent use, the brain adapts. When cannabis is suddenly stopped, those systems need time to rebalance, and withdrawal symptoms can follow.
The strength of cannabis products has increased over time, and concentrates, vapes and edibles can deliver much higher amounts of THC than older forms of marijuana. Heavier exposure may make dependence and withdrawal more likely. Our article on whether marijuana is addictive looks at the research in more depth.
Common Marijuana Withdrawal Symptoms
People who stop using cannabis after regular, heavy use often report:
- Irritability, anger or a short temper
- Nervousness or anxiety
- Trouble falling asleep or staying asleep
- Vivid or unusual dreams
- Decreased appetite or weight loss
- Restlessness
- Low mood
- Physical discomfort such as headaches, stomach pain, shakiness, sweating or chills
- Cravings for cannabis
Not everyone experiences every symptom. For many people, irritability and sleep problems are the hardest parts.
How Long Cannabis Withdrawal Tends to Last
Symptoms often begin within the first few days after stopping. They are commonly strongest during the first week or so, then gradually ease over the following weeks. Sleep difficulties and unusual dreams sometimes last longer than other symptoms.
This is a general pattern, not a promise. People who used more potent products, used many times a day or used for many years may find that withdrawal lasts longer or feels more intense. Having a plan for the first few weeks can make a big difference.
Practical Ways to Cope
Cannabis withdrawal is usually not medically dangerous on its own, but it can be uncomfortable enough to derail good intentions. Some strategies that help:
- Keep a regular sleep and wake schedule, and limit caffeine later in the day.
- Get some physical activity, even a daily walk.
- Eat regular meals even if your appetite is low.
- Tell trusted people you are cutting back so they can support you.
- Identify your triggers, such as certain friends, times of day or stress, and plan for them.
- Remove cannabis and accessories from your home.
Cutting Back Versus Quitting
Some people aim to stop completely, while others first try to reduce how often or how much they use. Either goal can be a starting point, but it helps to be honest about what has worked before. If earlier attempts to cut back slid back into daily use, stopping fully with support may be more realistic.
Whatever the goal, write down why it matters to you, such as sleeping better, saving money, feeling less anxious or being more present with family. Those reasons are useful to revisit when cravings or irritability make the plan feel harder.
When It Is Time to Get Help
Consider professional support if you have tried to cut back and could not, if cannabis is affecting your work, relationships or health, or if you find yourself using it to manage anxiety, depression or trauma symptoms. Cannabis use can also worsen some mental health conditions, and high-potency products have been linked to psychotic symptoms in some people.
Another warning sign is repeated bouts of severe nausea and vomiting with heavy long-term use, sometimes called cannabinoid hyperemesis syndrome. It needs medical attention.
If you also use alcohol, benzodiazepines or other substances, be especially careful. Withdrawal from alcohol and benzodiazepines can be life-threatening and should not be attempted abruptly without medical guidance.
Call 911 for a medical emergency. If you are having thoughts of suicide or feel in crisis, call or text 988 to reach the 988 Suicide and Crisis Lifeline.
