Weed Withdrawal Calculator

What does your withdrawal timeline look like?

Enter your usage pattern and quit date and get a personalized forecast built from 30 documented cannabis withdrawal symptoms — what is likely peaking now, what comes next, and what is already behind you.

How this forecast works

Each of the 30 symptoms on this site carries documented onset, peak, and resolution days from published withdrawal research. The calculator scales those windows by your usage intensity and years of use — heavier, longer use stretches the peak and recovery phases — and sorts every symptom into peaking, active, upcoming, or resolved for your current day. It shows documented ranges, not medical predictions: individual experiences vary.

Withdrawal timeline FAQ

What is the hardest day of weed withdrawal?+
For most people, days 2–4. Irritability, anxiety, and cravings peak in that window, while sleep problems often peak slightly later (days 3–7). By the end of week one, most physical symptoms are declining. Heavier, longer use shifts the whole curve later — the calculator above personalizes it.
How long does weed withdrawal last?+
The acute phase typically lasts 1–2 weeks. Sleep disturbances and vivid dreams can persist for 4–6 weeks, and psychological symptoms like low mood or irritability may take up to 8 weeks after heavy long-term use. Most people feel substantially better by day 30.
When does sleep get better after quitting weed?+
Insomnia usually peaks between days 3 and 7, then improves over 2–4 weeks as CB1 receptors recover. REM rebound — unusually vivid dreams — is strongest in weeks 1–3 and fades as your sleep architecture normalizes.
Is cannabis withdrawal dangerous?+
Unlike alcohol or benzodiazepine withdrawal, cannabis withdrawal is not medically dangerous — it is uncomfortable rather than hazardous. That said, if you experience severe depression, thoughts of self-harm, or symptoms that feel unmanageable, seek professional support promptly.
