Cannabis Half Life
Cannabis half-life explained: how long THC and CBD take to clear your body, what changes the timeline, and what it means for detection windows.
If you have ever wondered what the half life of THC actually means for your body and your routine, here is the short answer: THC clears from blood plasma with a half-life of roughly 1.5 to 4 hours, while its metabolites can linger in the body far longer. Knowing that difference helps you dose thoughtfully, plan around any testing, and choose products that match how you like to consume. Below is a plain-language breakdown before you browse our THC lineup.
What Is the Half-Life of THC?
A half-life is simply the time your body takes to eliminate half of a given dose. For THC itself, research generally points to about 1.5 to 4 hours in plasma, though the exact number shifts with dose, tolerance, and how the cannabinoid entered your system.
What Factors Influence the Half-Life of Cannabis?
Key Facts About THC Half-Life at a Glance
- Plasma half-life of THC: roughly 1.5 to 4 hours in most consumers.
- Metabolite half-life: THC-COOH is often reported at around 20 to 50 hours.
- Inhaled THC peaks within minutes and fades within a few hours.
- Edibles and tinctures absorb slowly, with effects lasting 4 to 8 hours or more.
- THC is fat-soluble, so it stores in body tissue and releases gradually.
- Use frequency, body composition, hydration, and metabolism all shift the timeline.
- Urine screening may detect metabolites for days after occasional use and weeks after heavy use.
- A half-life is not a measure of impairment, so never judge driving safety on a clock alone.
How Long Does THC Stay in Your System?
Detection windows depend on the test. Saliva and blood usually clear within hours to a couple of days, while urine can read positive for about three days after a single use and up to 30 days or more for chronic, heavy consumers. Hair testing reaches back much further than any of these.
Does How You Consume THC Change the Timeline?
Yes. Smoked flower, vapes, and concentrates deliver a fast peak and a quick decline, while edibles and tinctures are processed through the liver and produce a slower, longer-lasting curve. Product format matters as much as potency.
What to Look For in THC Products
Potency and format are printed on every label, and third-party lab results confirm cannabinoid content and screen for pesticides, heavy metals, mold, and residual solvents. Store flower and concentrates in a cool, dark, airtight container to protect terpenes and slow degradation, and keep edibles sealed away from heat. Start low with any new batch, since absorption and metabolism vary from person to person.
