How Long Does THCA Stay in Your System? (2025 Guide)

Plus, use our free Dosage Calculator to see how much hemp extract you should be taking.

What Is THCA?

THCA (tetrahydrocannabinolic acid) is the raw, non-psychoactive form of THC. On its own, it doesn’t make you feel “high.” But when heated through smoking, vaping, or baking, THCA converts into THC — the compound that delivers psychoactive effects.

Detection Times: How Long Does THCA Stay in Your Body?

Like THC, THCA can store in fat cells and exit your body gradually. Here’s how long common tests may detect it:

• Urine: 3–15 days (occasional use), up to 30+ days (heavy use)
• Blood: Up to 36 hours after last use
• Saliva: 1–3 days
• Hair: Up to 90 days

What Affects THCA Detection?

• Dosage & frequency of use
• Metabolism & body fat percentage
• Hydration & physical activity
• Type of drug test (urine vs. hair vs. saliva)

Does THCA Show Up on Drug Tests?

Yes. Even though THCA itself isn’t intoxicating, many drug tests convert THCA to THC during analysis, which can lead to a positive result. If you’re in a tested environment, proceed with caution.
