How Long Does Weed Stay in Your System?
When you use weed, also known as cannabis or marijuana, your body absorbs THC (tetrahydrocannabinol), the chemical responsible for the “high.” This THC and its by-products (called metabolites) can stay in your system for a while, even after the effects have worn off. How long they stay depends on how much and how often you use weed, as well as your body’s unique factors.
Types of Drug Tests and Detection Windows
Urine Test: This is the most common method for detecting weed.
- Single use: Detectable for up to 3 days.
- Moderate use: (4 times per week) Detectable for 5–7 days.
- Chronic use: (Daily) Detectable for 10–15 days.
- Heavy use: (Multiple times daily) Detectable for more than 30 days.
Blood Test: Usually detects weed used within the last 2–12 hours, but in heavy users, it can be detected up to 30 days.
Saliva Test: THC can enter your saliva through smoking or ingesting cannabis. It’s usually detectable within a few hours of use, but in frequent smokers, it can be detected up to 72 hours later.
Hair Test: This method can detect weed use for up to 90 days. THC metabolites get into your hair follicles through your bloodstream and sweat.

How THC Moves Through Your Body
When you smoke or ingest weed, THC enters your bloodstream. It’s then broken down in your liver, producing over 100 different metabolites, some of which can stay in your system for a long time. These metabolites are stored in fat cells, making them hard to get rid of quickly.
Factors That Affect THC Detection
Several factors influence how long THC stays in your system:
- Body fat: More fat means THC metabolites stay longer.
- Metabolic rate: A slower metabolism results in a longer detection window.
- Usage habits: Frequent and heavy use extends the detection time.
- Potency: Stronger weed with higher THC content stays in your system longer.
Can You Speed Up THC Metabolism?
Unfortunately, there’s no quick fix to clear THC from your system. Staying hydrated, exercising, and eating a healthy diet might help a little, but your body needs time to naturally metabolize and eliminate THC.
How Quickly Do You Feel Weed’s Effects?
- Smoking: Effects can be felt almost immediately.
- Ingesting: It may take 1–3 hours for effects to peak.
Common effects include altered senses, changes in mood, and difficulty concentrating. In some cases, high doses can cause anxiety, hallucinations, or even psychosis.
How Long Do the Effects Last?
Short-term effects usually wear off after 1–3 hours. However, long-term effects, especially from chronic use, may last days, weeks, or even be permanent.
Remember, It’s a Journey
Marijuana can typically be detected in the blood for up to 2 to 12 hours after use. However, in cases of heavy use, it has been found detectable for up to 30 days later.
Frequently Asked Questions
How long does THC stay in the body? THC metabolites can stay in your body from a few days to several months, depending on usage frequency and your body’s metabolism.
Will one hit of weed show up on a urine test? Yes, even a single use can be detected in a urine test for up to 3 days.

Final Thoughts
THC and its metabolites can linger in your system for a long time, depending on various factors. Different drug tests have different detection windows, so it’s important to understand how your usage habits might affect your test results.
