How Long Does CBD Stay in Your System? (2025 Guide)
One of the most common questions before trying CBD is: “How long does CBD stay in your system?” The short answer: it varies based on your weight, metabolism, how often you take it, the product type, and your dose. Below we break it down — and include a free CBD Dosage Calculator so you can find a personalized starting point.
What Affects How Long CBD Stays in Your Body?
- Weight & body fat: CBD is fat-soluble and may linger longer with higher body fat.
- Dosage & frequency: Larger and more frequent doses take longer to clear.
- Product type: Vapes clear fastest; edibles last longer due to digestion.
- Metabolism: Faster metabolisms usually clear CBD sooner.
CBD Half-Life & Elimination Timeline
- Tinctures/Oils: commonly detectable ~2–5 days
- Gummies/Capsules: ~3–7 days
- Vape/Flower: ~1–2 days (fastest onset/clearance)
- Topicals: minimal systemic absorption
Can CBD Show Up on a Drug Test?
Standard tests target THC, not CBD. Full-spectrum products can contain trace THC (<0.3%), which may accumulate with repeated use. If you’re tested, consider broad-spectrum or THC-free options.
