Cannabis withdrawal doesn't hit hardest on day one. It builds. THC is stored in body fat and released slowly, so the first 24 hours are often quiet, symptoms ramp up over days two and three, and the peak usually lands somewhere in days three to six before easing.
That delay catches people off guard. You get through the first day feeling fine, assume that's the whole thing, and then day four is worse — which reads as "it's getting worse, this isn't working" when it's actually the expected shape.
What lands at the peak
- Sleep. Usually the worst part — long time to fall asleep, waking in the night, and dreams intense enough to be their own disruption. Dreams about using are common and don't mean anything.
- Irritability. A shorter fuse than normal, snapping at things that wouldn't usually register.
- Restlessness and low mood. Physical fidgetiness, difficulty settling, a flat or down feeling.
- Appetite down. Often with some mild stomach unease. It comes back.
- Night sweats. Common and harmless, mostly in the first several days.
Why knowing the timing helps
If you expect days three to six to be the hard stretch, three things change. You don't read the peak as failure. You can clear your schedule a little — fewer commitments, an earlier night, less asked of yourself. And you can set a narrow goal for those specific days: get through them. Not feel good, not be productive, not handle it gracefully. Just get to day seven, where it starts easing.
The withdrawal timeline marks which phase you're in based on how long you've been at zero, so a rough night shows up as "expected for this phase" instead of a mystery.
After the peak
From about day seven, the physical intensity noticeably drops. Cravings become less constant and more like distinct waves with gaps between them. Sleep is usually the last thing to settle — see sleep and the vivid dreams for roughly how long that takes.
