After longer, regular use, the body often reacts to stopping cannabis with withdrawal symptoms. Typical are sleep problems, irritability, restlessness, less appetite and intense dreams. The symptoms are distressing but usually not physically dangerous and as a rule they ease. If you have other health conditions or strong mental health symptoms, talk to your doctor first.
Whether you want to end a treatment prescribed by a doctor or give up recreational use: here you can find out what happens in which phase and what can help you.
How common are cannabis withdrawal symptoms?
A meta-analysis with data from more than 23,000 people found a withdrawal syndrome in about 47 per cent of people with regular or problematic cannabis use. The risk rises with daily use, high amounts of THC and long duration. People who only use occasionally often notice little when they stop.
What are the typical symptoms?
Mental: irritability, anger, nervousness, anxiety, low mood, craving for cannabis. Sleep: problems falling and staying asleep, very vivid dreams. Physical: less appetite, stomach pain, sweating, shaking, headache, chills.
Medically, this is called cannabis withdrawal syndrome, and it is described in the international diagnostic systems.
How long does cannabis withdrawal last?
The first symptoms usually start 24 to 72 hours after the last use. As a rule they peak in the first week. Most symptoms ease clearly after one to two weeks. Sleep problems and vivid dreams can last a few weeks longer.
At the same time, the endocannabinoid system recovers: the CB1 receptors become more sensitive again within a few weeks.
What helps during this time?
Fixed bedtimes, no screens before sleep, little caffeine in the afternoon. Daily exercise, regular meals even if you have little appetite, enough to drink. Tell people who support you, and avoid situations linked to using.
Do not replace cannabis with alcohol or sleeping pills without medical advice. If your sleep stays poor for weeks, talk to your GP (Hausarzt). What studies say about cannabis and sleep is explained in Cannabis for insomnia.
How do you stop medical cannabis?
A treatment prescribed by a doctor should not be stopped abruptly or on your own. Discuss stopping with your doctor. Often the amount is reduced step by step, which can soften withdrawal symptoms.
Also bear in mind: the symptoms for which treatment was started can come back. Then a plan for further treatment is needed.
When is professional help a good idea?
If stopping does not work despite several attempts, if you notice strong anxiety, low mood or thoughts of self-harm, or if cannabis determines your daily life, work and relationships. In Germany, places to turn to are your GP practice, addiction counselling services (Suchtberatungsstellen) and psychiatric outpatient clinics. If you have suicidal thoughts: TelefonSeelsorge crisis line 0800 111 0 111 or emergency number 112.
