How Long Does Weed Stay in Your System?

Wondering how long weed lasts in your system? Learn about detection times by method and what affects THC duration in your body.

Whether you’re a regular consumer or an occasional toker, chances are you’ve wondered: how long weed lasts in your system. It’s a common question, especially for those facing drug testing for employment or medical procedures. At Scarlet Reserve Room in Englishtown, we believe in empowering our community with honest, helpful education—so here’s everything you need to know.

🧪 What Affects How Long Weed Stays in Your System?

The answer depends on several factors:

  • Frequency of Use: Daily consumers can retain THC metabolites for weeks.

  • Consumption Method: Smoking, vaping, edibles, or dabs? It matters.

  • Your Body: Metabolism, body fat percentage, hydration, and overall health play a role.

  • Testing Type: Urine, saliva, blood, or hair tests have very different detection windows.

💨 By Method: How Long Weed Lasts in Your System

Let’s break it down by consumption method and average detection times:

1. Smoking or Vaping

THC enters your bloodstream quickly, peaking within minutes.

  • Urine Test: 1–3 days (occasional use), up to 30+ days (frequent use)

  • Saliva Test: Up to 72 hours

  • Blood Test: 1–2 days

  • Hair Test: Up to 90 days

2. Edibles

Since THC is metabolized through your liver, the onset is slower—but the effects (and detection window) tend to last longer.

  • Urine Test: 3–5 days (occasional), up to 30 days (frequent)

  • Saliva: Up to 72 hours

  • Blood: Up to 2 days

3. Concentrates or Dabs

Due to high THC levels, concentrates can stick around longer, especially in chronic users.

  • Urine Test: Up to 30+ days with heavy use

  • Hair Test: Consistently up to 90 days

🔍 What About Detox or Cleansing?

There’s a lot of misinformation around detox drinks and fast cleanses. While hydration, healthy eating, and time can support your body’s natural detox process, no product can guarantee passing a test. The only foolproof method? Abstinence and patience.

🧠 Quick FAQ

Q: Can secondhand smoke cause a positive result?
A: Unlikely in casual exposure. You’d need prolonged, enclosed exposure to reach detectable levels.

Q: Will CBD products show up?
A: Full-spectrum CBD may contain trace THC. Stick with THC-free broad spectrum if you’re concerned about testing.
