Cannabis Withdrawal Symptoms and How Long They Last

Save

After stopping regular cannabis use, common withdrawal symptoms include irritability, anxiety, restlessness, trouble sleeping, vivid dreams, and reduced appetite. They usually begin within a day or two, peak in the first week, and ease over one to two weeks, though sleep can take longer to settle. Heavier use tends to mean stronger symptoms.

What withdrawal usually feels like

Common symptoms after stopping regular use include irritability, anxiety, restlessness, difficulty sleeping, vivid or unsettling dreams, decreased appetite, headaches, sweating, and low mood. The more frequent and heavy the use, the more noticeable withdrawal tends to be, which is why how often you use is the single most useful question clinicians ask when gauging risk and likely difficulty quitting 1. Symptoms reflect your body adjusting and are not a sign of danger.

A typical timeline

For many people, symptoms begin within one to two days of the last use, peak around days two to six, and largely fade over one to two weeks. Sleep problems and vivid dreams can persist longer. Everyone is different, and heavier or longer-term use can stretch the timeline. Because withdrawal anxiety and insomnia can look like a separate anxiety or sleep condition, a brief screen and conversation with a clinician can help sort out which is which 2.

What helps you get through it

Steady sleep and wake times, daytime light and exercise, hydration, and limiting caffeine and alcohol all ease the rough patch. Plan replacements for your usual triggers, and lean on supportive people. Structured behavioral support, the kind offered within the screening, brief intervention, and referral to treatment (SBIRT) framework, helps people stay the course and is part of established care for substance use 3.

When cannabis withdrawal needs a clinician

Reach out if symptoms are severe, last beyond two weeks, or make it hard to function. A clinician can use a validated screen to gauge whether your use is a cannabis use disorder rather than guessing 2, rule out medical or mental health conditions that mimic or worsen withdrawal, such as an anxiety disorder or a sleep disorder, and offer evidence-based counseling like CBT plus referral to more intensive treatment when needed, within the SBIRT model 34. For a teen, a clinician can also tailor care to that developmental stage and coordinate with family and school 5.

Common questions

Withdrawal is uncomfortable but not medically dangerous for most people. Still, if symptoms are severe or you have thoughts of self-harm, reach out to a clinician or crisis line right away.

Sleep disturbance and vivid dreams are among the most common and longest-lasting withdrawal effects. Steady sleep routines help; if insomnia persists, a clinician can tell withdrawal apart from a sleep disorder 2.

Generally yes. More frequent and heavier use tends to produce more noticeable withdrawal, which is why clinicians ask about frequency when gauging what to expect 1.
