If you stopped a day or two ago and you feel irritable, wired, hot, sick to your stomach and unable to eat, you are not broken and nothing rare is happening to you. That combination is the most commonly described pattern in cannabis withdrawal research, and the first 72 hours is when it shows up.
Here is what studies generally find, roughly hour by hour, plus what people commonly do to get through it. None of this is a treatment plan or a promise. Everybody's body and history are different, and a doctor or a counselor who knows you can say things a web page cannot.
When withdrawal actually starts
Symptoms usually begin sooner than people expect. Reviews of the clinical literature put onset at about 24 to 48 hours after the last use, with most symptoms peaking around days two through six (Connor et al., Addiction, 2022). A 50-day study that tracked daily users through abstinence found onset between days one and three and peak severity between days two and six (Budney et al., Journal of Abnormal Psychology, 2003).
So the first 72 hours are mostly the climb, not the peak. That is worth knowing in advance, because a lot of people quit, feel rough on day two, assume it will keep getting worse forever, and go back.
Withdrawal is also not universal. A meta-analysis pooling 23,518 people found cannabis withdrawal syndrome in about 47 percent overall, but only about 17 percent in general population samples versus much higher rates in people in treatment (Bahji et al., JAMA Network Open, 2020). Heavier and more frequent use is associated with a higher chance of it. If you used daily for years, expect more. If you used on weekends, you may feel very little.
Day 1: mostly quiet, then restless
The first 24 hours are often the mildest part. Many people report feeling fine, even proud, through the first evening. What tends to appear first is restlessness and trouble settling down, and then the first bad night of sleep.
Sleep is usually the earliest thing to go. The first night without cannabis often takes longer to fall asleep than you are used to, and it is common to wake up several times. That is covered in more depth in our articles on sleep and on weed dreams.
Day 2: the irritability day
Day two is when most people notice mood. The symptoms that researchers consistently identify in cannabis withdrawal include irritability, anger or aggression, nervousness or anxiety, restlessness, depressed mood, appetite or weight loss, and physical symptoms such as headaches, sweating, chills, stomach pain and nausea (NIDA, Cannabis (Marijuana)).
The irritability is often out of proportion to whatever set it off. People describe snapping at a partner over dishes, or feeling a flash of rage at traffic that would normally be nothing. It is useful to say out loud to the people around you, in advance: I quit two days ago, I am going to be short with people, it is not about you.
Appetite loss usually shows up around here too. Food tastes like nothing. In the Budney study, measurable decreases in both appetite and body weight were part of the withdrawal pattern. Most people find it comes back over the following one to two weeks.
Day 3: near the top of the curve
By day three you are usually at or near peak severity. Common reports at this point are night sweats, vivid or disturbing dreams if you are sleeping at all, a low flat mood, physical tension, and cravings that arrive in waves rather than constantly.
A study using a daily withdrawal scale found that the symptoms people rated as most disruptive to normal functioning were trouble getting to sleep, angry outbursts, craving, loss of appetite, irritability, and nightmares or strange dreams (Allsop et al., PLOS ONE, 2012). That is a fair description of day three for a lot of heavy users.
What people commonly find helps
There is no medication approved in the United States for cannabis withdrawal. What clinical reviews describe as first-line is unglamorous: supportive counseling, knowing what to expect, sleep support, exercise and nutrition, and coping skills (Connor et al., 2022). In practice, that tends to look like this.
Drink water and eat on a schedule, not on appetite. If nothing sounds good, small and bland and regular beats waiting to feel hungry. Sweating and reduced intake can leave you feeling worse than the withdrawal alone.
Move your body, even a little. Walking, jogging, yoga and strength training all showed benefits for depressed mood in a large network meta-analysis of randomized trials (Noetel et al., BMJ, 2024). A twenty-minute walk is not a cure for withdrawal, but it is one of the few things with real evidence behind it for mood, and it is free.
Keep a fixed wake-up time. Sleep is going to be disrupted for a while no matter what. Getting up at the same time and getting outside into daylight early gives your body clock something steady to hold onto.
Plan for the evening. Most people's habit was attached to a specific time and place. Day three at 9pm in the usual chair is harder than day three at 9pm doing something else.
Expect the waves to pass. Cravings tend to rise, hold and fall over roughly twenty minutes. You do not have to fight one down forever, only ride the one you are in.
When to get someone involved
Reach out if the low mood is not lifting, if you feel hopeless, if you are using other substances to cover the gap, or if you have a mental health condition that is getting worse. Withdrawal is uncomfortable, but a sharp drop in mood deserves a real person, not a search bar.
