How Long Does THCA Stay in Your System?
If you’ve been using cannabis products and wondering how long does THCA stay in your system, you’re not alone. As more people turn to hemp-derived products for wellness or recreational reasons, understanding what happens inside your body after use becomes essential — especially when drug testing is a concern.
Let’s break it down clearly, without the fluff.
What Is THCA?
THCA stands for tetrahydrocannabinolic acid, a non-psychoactive cannabinoid naturally found in raw and freshly harvested cannabis plants. It’s the precursor to THC — the compound that gets you high. When heated (by smoking, vaping, or cooking), THCA converts to THC through a process called decarboxylation.
So, while THCA itself doesn’t cause a high, it can still trigger a positive drug test because it turns into THC in the body or during lab testing.
How Long Does THCA Stay in Your System?
The amount of time THCA remains in your body depends on several key factors:
1. Frequency of Use
- Occasional Users: 1–3 days
- Regular Users: 7–14 days
- Heavy Users: 30+ days
Even if you’re consuming THCA raw or in small amounts, frequent use builds up in fat cells, making it stick around longer.
2. Body Fat and Metabolism
THCA and THC are fat-soluble, meaning they’re stored in your body fat. The higher your body fat percentage and the slower your metabolism, the longer THCA might linger.
3. Hydration and Activity Level
Staying hydrated and active helps flush out toxins more quickly. Sedentary lifestyle = slower elimination.
4. Method of Consumption
- Raw consumption (juicing, tinctures) may stay shorter than inhaled THC, but lab tests still detect the THC it can convert into.
- Smoking or vaping THCA-rich products = faster decarboxylation → higher THC levels → longer retention.
Drug Testing and THCA: Can It Show Up?
Yes, THCA can trigger a positive THC test result, especially on urine drug screens (the most common type). While some tests target active THC (delta-9), others look for metabolites — and THCA may indirectly contribute to them if it’s decarboxylated.
Detection Windows by Test Type:
Test Type |
Detection Time |
| Urine Test | 3 to 30+ days |
| Blood Test | Up to 36 hours |
| Saliva Test | 24–72 hours |
| Hair Test | Up to 90 days |
How to Get THCA Out of Your System Faster
If you’re prepping for a drug test or just want to detox, here are some smart tips:
- Hydrate like crazy: Water helps flush metabolites.
- Exercise regularly: Burn fat, release stored THC/THCA.
- Eat clean: High-fiber, antioxidant-rich foods help cleanse the body.
- Avoid more THCA: Sounds obvious, but even small “harmless” amounts can delay detox.
Warning: Detox products and “miracle cleanses” are often scams. Stick to natural methods.

Is THCA Legal?
In many U.S. states, THCA is legal under federal law if derived from hemp (containing <0.3% delta-9 THC). However, state laws vary — and some drug tests don’t care about legal technicalities. Always check your local laws and employer policies before using.
Final Thoughts: Know Before You Dose
While THCA doesn’t get you high in its raw form, it’s not completely off the hook. Once decarboxylated, it becomes THC — and that’s what drug tests look for.
So, how long does THCA stay in your system? It could be a couple of days or a whole month, depending on your habits, body, and lifestyle. If you’re concerned about testing or want to be cautious with your cannabinoid use, it’s best to plan ahead.
FAQs:
1. Does THCA show up on a drug test?
Yes, especially if it turns into THC through heat or digestion.
2. Is THCA legal?
Yes, federally — if it’s hemp-derived. But some states regulate it, so check your local laws.
3. Can you detox from THCA faster?
Hydration, exercise, and a clean diet can help. But there’s no guaranteed “quick fix.”
Bottom line:
THCA may be mild in raw form, but it’s still a player in your body’s chemistry. Be informed, be responsible, and always know what you’re putting into your system.
