Marijuana Withdrawal

What Is Marijuana Withdrawal?

Marijuana abstinence syndrome, or withdrawal, is characterized by disturbances in mood, sleep, and appetite. An estimated 50% to 96% of those dependent on marijuana will experience withdrawal symptoms when they decide to quit using the drug.1,2

Marijuana Withdrawal Symptoms

Marijuana dependence and withdrawal have been a topic of controversy for years. However, research studies, as well as reports of users in treatment, strongly suggest the presence of withdrawal symptoms in chronic and heavy marijuana users.

The following is a list of symptoms that may be experienced by those going through marijuana withdrawal:2

  • Insomnia or sleep disturbance
  • Loss of appetite or weight loss
  • Irritability
  • Tremors or feeling jittery
  • Restlessness
  • Fever
  • Feelings of depression
  • Headache
  • Sweating
  • Nervousness
  • Anxiety
  • Anger or aggression

Some people who abuse marijuana may also experience:2
  • Yawning.
  • Fatigue.
  • Concentration problems.
  • Increased appetite.
  • Excessive sleep.

Withdrawal effects can make it difficult to quit using and also contribute to relapse. Some individuals report using other substances to alleviate unpleasant withdrawal symptoms.2

The number of symptoms experienced and their severity will depend upon the length of time a person has been using marijuana and the amount used. The symptoms are seldom severe enough to warrant medical care, but therapy may help promote long-term sobriety.2

Marijuana Withdrawal Timeline

The onset of marijuana withdrawal symptoms generally occurs within 1–3 days after cessation of use.2 The symptoms typically peak within 1 week and dissipate within about 2 weeks.2

Each person will react to marijuana intoxication and withdrawal differently. One person may experience severe withdrawal symptoms for weeks, while another may not have any symptoms at all. Therefore, the timeline that follows may vary from person to person.1,2,3,4

  • First 24-48 hours: Increased salivation, restlessness, tremors or feeling jittery, increased body temperature.
  • 2-3 days to a week: Insomnia, loss of appetite, irritability, anger, and/or aggression.

Some symptoms, such as sleep problems, may persist for more than 30 days after quitting marijuana.2

Post-Acute Withdrawal Syndrome

Some users may also experience withdrawal effects after the initial detox period, a phenomenon known as post-acute withdrawal syndrome (PAWS). Symptoms can last for weeks or months and include:

  • Anxiety.
  • Sleep problems.
  • Memory problems.
  • Fatigue.
  • Lack of motivation.
  • Irritability.
  • Depression.
  • Cravings.

A review of 19 studies on marijuana found that some recovering marijuana users had sleep problems and strange dreams 45 days after abstinence.7

Causes of Withdrawal

Chronic marijuana or cannabis users typically develop tolerance,2 meaning that they require increasing amounts of the drug to experience the desired effects. Increased use can also lead to physical dependence. When dependence occurs, the user experiences withdrawal symptoms when they stop taking the drug.6

Although the effects of withdrawal are not severe or life-threatening, more than 50% of users who attempt to quit using marijuana have reported symptoms. In addition, many users find the symptoms uncomfortable and begin using marijuana again to feel better.2

Treatment for Marijuana Withdrawal

If you believe that you or a loved one may have developed a dependence on marijuana, there are various levels of treatment available. One type of treatment isn’t superior to another; it all depends on your needs and life situation.

Seeking professional help can make the detoxification period more comfortable and reduce the likelihood of relapse.

Below is an explanation of each level of care and what you can expect to get from each.

  • Detox center: A residential detox program is a short-term program that provides 24-hour supervision throughout the withdrawal period. The trained staff directly monitor symptoms and provide medications to mitigate uncomfortable symptoms, such as insomnia and anxiety. Once the detox program is completed, people either return home or enroll in an outpatient or inpatient treatment program.
  • Inpatient rehab facility: Inpatient treatment centers also provide 24-hour supervision for the duration of your stay at the facility. The length of the program varies from 28 days to several months. Services usually include detox and individual, family, and group therapy. Additional services, such as nutritional counseling, yoga, art therapy, meditation, and recreational therapy, may also be included.
  • Partial hospitalization programs (PHP): Partial hospitalization programs are intensive outpatient programs that consist of group therapy sessions that are held at hospitals or other facilities that avail access to medical services. The groups are run by therapists who specialize in substance abuse treatment and mental health. These programs also provide medication management, if necessary, and give you the opportunity to live at home while receiving a high level of care. They may provide detox.
  • Intensive outpatient programs (IOP): Intensive outpatient programs are similar to partial hospitalization programs. This form of outpatient treatment will, in general, be conducted over the course of half the day or less, and in most cases will not provide medication management. You will usually need to have a physician manage any medications you may be taking.

Other outpatient programs include individual therapy, group counseling, and support groups.

  • Individual therapy: You meet one-on-one with a therapist who helps uncover issues influencing your marijuana addiction, as well as identify negative thoughts, beliefs, and behaviors. A therapist can also address co-occurring mental health problems, such as anxiety, depression, bipolar disorder, and schizophrenia.
  • Group counseling: A mental health specialist leads a therapy session focused on sober skills and coping strategies. Groups are comprised of other people struggling with addiction.
  • Support groups: Support groups, such as Marijuana Anonymous, use a 12-step approach to recovery, while SMART Recovery is an alternative group that uses evidence-based practices. Support groups provide you with an encouraging and judgment-free environment to share and learn from others.

Facilities may also prescribe medications to manage symptoms such as anxiety and insomnia.
