🧠 How THC Detox Works
THC, the main psychoactive compound in cannabis, is fat-soluble — meaning it stores in your body’s fat cells. That’s why detoxing isn’t as simple as “wait a few days.”
Several factors affect how long weed stays in your system:
- How often you use
- How long you’ve been using
- Your body fat %
- Your weight
- How much you exercise
- The type of drug test
🔍 What the Weed Detox Calculator Measures
Here’s what our calculator considers:
| Factor | Impact on Detection Time |
|---|---|
| Usage Frequency | Heavy use = longer detection window |
| Usage Duration | Long-term use = more THC stored |
| Body Fat % | Higher fat % = slower THC release |
| Exercise Level | Boosts metabolism = quicker detox |
| Test Type | Hair tests are hardest to pass |
You’ll get a realistic time frame tailored to your situation — no more guesswork.

⚗️ THC Detection Window by Test Type
| Test Type | Typical Detection Time |
|---|---|
| Urine | 3 to 90 days |
| Blood | 1 to 7 days |
| Saliva | 1 to 3 days |
| Hair | Up to 90 days+ |
Urine tests are the most common — and this calculator defaults to them. You can change your test type for more accurate results.
