Seven days. If you're reading this at some rough hour of the morning wondering whether you're supposed to feel this bad a week in, here's the honest answer: for a lot of people, day seven is close to the worst of it, or just past it.
Not everyone. Cannabis withdrawal varies enormously between people, and there's no fixed schedule you're owed. But the shape researchers have documented is consistent enough to be useful, so here's what it says.
Where you are on the curve
Reviews of the clinical literature put withdrawal onset at roughly 24 to 48 hours after last use, with most symptoms peaking around days two through six (Connor et al., Addiction, 2022). A 50-day study that tracked daily cannabis users through abstinence found essentially the same pattern: onset in the first one to three days, peak severity around days two through six, and most symptoms resolving within about two weeks (Budney et al., Journal of Abnormal Psychology, 2003).
That puts day seven right at the point where the curve is supposed to be bending downward. If the last few days felt like a slow easing rather than a continued climb, that lines up with what the research describes. If it doesn't feel that way yet, that's within the range too — heavier, longer-term daily use is associated with a rougher and sometimes longer course.
It's also worth knowing that withdrawal itself isn't universal. A meta-analysis pooling data on more than 23,000 people found a recognizable cannabis withdrawal syndrome in about 47 percent overall, but only around 17 percent among general-population samples, compared with much higher rates among people in treatment for heavy use (Bahji et al., JAMA Network Open, 2020). If you used daily for years, expect more of this. If your use was lighter or less frequent, you may have felt surprisingly little, and that's normal too.
Why everyone's week one looks different
How rough this week has been depends a lot on how you used before you quit. Severity and duration of withdrawal tend to track with how heavily and how long someone used: daily, long-term, higher-quantity use is associated with a more pronounced course, while lighter or less frequent use is associated with milder or even negligible withdrawal (Bahji et al., JAMA Network Open, 2020). Using tobacco or alcohol alongside cannabis can also complicate the picture, since withdrawal from more than one substance at once doesn't necessarily separate cleanly.
None of that is a competition. If your week has been mild, you don't need to brace for a delayed crash that matches someone else's story. If it's been rough, that's consistent with your history, not a sign you're handling it badly.
What's normal to still feel
Irritability, restlessness, anxiety, low or flat mood, disrupted appetite, and cravings that come in waves are all part of the recognized withdrawal picture (NIDA, Cannabis (Marijuana)). At one week, these often feel less acute than they did around day three, but they don't usually vanish overnight — think fading, not switching off.
It's worth putting the discomfort in context. When researchers compared self-reported withdrawal severity in daily cannabis users and daily cigarette smokers who had recently tried to quit, the two groups scored similarly on overall withdrawal discomfort (Budney et al., Journal of Substance Abuse Treatment, 2008). If anyone has told you quitting weed should be easy because it's "not really addictive," that comparison is a fair answer.
Sleep and dreams
Sleep is usually the slowest thing to recover, and week one is often when it's at its worst: longer to fall asleep, more waking overnight, and vivid or unsettling dreams. That's consistent with what sleep researchers have measured — cannabis use suppresses REM sleep, and stopping produces a rebound, so you can end up with more REM, and more intense REM, than your usual baseline for a while (Angarita et al., Addiction Science & Clinical Practice, 2016). We've written more on both of these specifically: our guides on insomnia after quitting and on the dreams go into the mechanisms and what tends to help.
What usually improves from here
For most people, appetite starts coming back around now, irritability tends to flatten out, and physical symptoms like sweating or stomach upset are usually among the first to fade (Budney et al., 2003).
There's a plausible biological reason the trend keeps moving in your favor. Brain imaging research has found that the CB1 receptors THC acts on are present in lower numbers in people who use cannabis heavily and daily, and that after about four weeks of monitored abstinence, receptor density returns to levels close to those of people who don't use cannabis (Hirvonen et al., Molecular Psychiatry, 2012). You're roughly a quarter of the way through that window. Your brain isn't stuck where it is right now.
The point most people don't reach
Here's a detail worth knowing if you made it to day seven. In a study that tracked withdrawal daily in cannabis-dependent volunteers, the people who relapsed did so after an average of about five days, right around the point where withdrawal was interfering most with daily functioning (Allsop et al., PLOS ONE, 2012). That's a statistically ordinary place to give up, and it's usually right before things start easing. If you're past it, you're past the point where most attempts end.
When it deserves a doctor's attention
Most of what's described here is uncomfortable but expected. A few things are worth a real conversation with a doctor rather than another night of waiting it out: mood that keeps dropping instead of leveling off, a sense of hopelessness, physical symptoms severe enough that you can't keep food or fluids down, or a pre-existing mental health condition that's getting noticeably worse.

If you're deciding whether to keep going
A week without something you used daily is a real thing you did. The research suggests the next stretch tends to be easier than the one behind you, particularly for the symptoms that felt most disruptive.
