When someone stops using marijuana, a common question is: How long will it stay in my system? The answer isn’t always simple. It depends on several factors, from how often someone uses it to their metabolism and overall health.

In this blog, we’ll explore how long marijuana and its compounds linger in the body, what drug tests detect, and what this might mean for someone navigating recovery.

What Your Body Stores?

The primary compound in marijuana that drug tests look for is THC (tetrahydrocannabinol). When you use marijuana, THC gets stored in fat cells and is released slowly over time. That’s why marijuana tends to stay in the system longer than many other substances.

Detection Times: What the Research Shows

Here’s a general breakdown of how long THC might show up on drug tests:

Test Type Detection Window
Urine Test 3 to 30+ days (varies by frequency)
Blood Test Up to 3 days for occasional use
Saliva Test 24 to 72 hours
Hair Test Up to 90 days

Keep in mind, daily or heavy users might test positive for longer than these averages.

What Affects How Long Marijuana Stays in Your System?

  • Frequency of use: More frequent use = longer detection.
  • Body fat percentage: THC is stored in fat cells.
  • Metabolism: Faster metabolism helps process THC more quickly.
  • Hydration & physical activity: These may play a role in how THC is flushed.

There’s no guaranteed way to “flush” THC instantly from your body. Claims about detox drinks or home remedies often don’t hold up to science.

Why Does It Matter for Recovery?

For someone in early recovery or navigating sobriety, knowing how long substances stay in the system can help with planning, accountability, and medical decisions. It also helps reduce anxiety around routine drug screenings, especially if you’re in a workplace or treatment program.
