Marijuana has been more socially accepted and legalized in many states. Thus, it’s no wonder that many forget about its impact on the body and on recovery.
Whether you’re trying to get clean, preparing for a drug test, or just curious about how long cannabis lingers in your system, the answer isn’t always simple.
The amount of time weed stays in your system depends on several personal and biological factors. Understanding this timeline can be important for your health, especially if you’re starting the journey toward sobriety.
How THC Works in the Body
When you use marijuana, your body absorbs THC (tetrahydrocannabinol), the psychoactive compound responsible for the “high.”
THC quickly breaks down into byproducts called metabolites, particularly THC-COOH. These metabolites are what most drug tests look for, not the active THC itself.
Because THC is fat-soluble, it’s stored in your body’s fat cells. That means it can take much longer to leave your system compared to water-soluble substances like alcohol completely.
Even after the high wears off, traces of THC can remain in your system for days, weeks, or even months.
How Long Can Weed Be Detected?
Detection times vary based on the type of drug test used. Here’s a breakdown of the most common types:
1. Urine Tests
Urine testing is the most widely used method in workplace and treatment settings.
- Occasional users (once a week or less): 3–7 days
- Moderate users (a few times a week): 7–21 days
- Heavy or daily users: 30+ days (in some cases, up to 60 days)
2. Blood Tests
THC only remains in the bloodstream for a short time.
- Occasional users: Up to 1–2 days
- Frequent users: Up to 7 days
3. Saliva Tests
These are less invasive and detect very recent use.
- All users: Up to 24–72 hours
4. Hair Tests
Hair tests can detect THC long after use, making them useful for identifying chronic use patterns.
- All users: Up to 90 days (based on 1.5 inches of hair)
Factors That Affect How Long Weed Stays in Your System
No two people are exactly alike and several factors can influence how quickly THC leaves your body. This includes:
- Frequency of Use: Daily or long-term use means THC builds up in fat cells, taking longer to clear.
- Body Fat: More fat can mean a longer retention time.
- Metabolism: A faster metabolism may help eliminate THC more quickly.
- Hydration & Exercise: Staying hydrated and active can help flush your system—but it won’t drastically shorten detection time.
- Potency: Higher THC levels in the cannabis used can extend how long it stays in your system.
- Method of Use: Smoking and vaping may clear faster than edibles, which take longer to metabolize.
The Truth About Detox Myths
If you search online, you’ll find plenty of advice on how to “flush” THC from your system quickly. Popular suggestions include:
- Drinking cranberry juice or vinegar
- Taking detox pills
- Chugging gallons of water
- Using synthetic urine
The truth?
Most of these “quick fixes” are ineffective, and some can be dangerous. The only proven way to clear THC from your system is time and a healthy lifestyle.
Medical detox, when needed, offers a safe and supervised environment for your body to begin healing naturally.
Why This Matters in Recovery
Even after someone stops using marijuana, THC can remain in the system for weeks. While it’s no longer causing intoxication, its presence can:
- Trigger cravings or mood swings
- Complicate early stages of recovery
- Influence drug test results in treatment or legal settings
